Newsletter No 82

17 January, 2018

Maybe you should skip back to my last Newsletter, from a year back, and see how scarily correct I was with my prediction for last year.
Seeing how many tenders were advertised over the holiday season I am led to believe something foul is afoot.
Namibia is Bankrupt, right ? And now we have money again ?
This means the money is lent, and not given to us ?    And that means it has to be repaid ! With what ?

 The below is what was developed for your Revo Hilux/Fortuner 2.8 GDi:

As you can see it is a unit you can connect up yourself and is fully tunable.

We are busy on a separate development on the 2.4 GDi Hilux (only with manual trans) for 5000 N$, which is soldered in (as opposed to the plug-in unit picture above) and has no separate injector driver.

Here is a nice independent article on Unichip tuning


With the flooding of the market of light systems, including the debated light-bars, I had to make the decision to discontinue spot-lights in the future.
For now I still stock the following:

Light Force     Btw the last 3 items are rail mounted (rail for mounting on sling swivel included) bipods

KC Daylighter pricelist

And for the old Hilux, with the square headlamps we still have a set of the famous PIAA replacement driving lights:

I wish people would behave civilised, so this would not be necessary :(


Daily I get about 40+ requests on K&N air filters, via phone, Email Faceboook and WhatsApp.
I do not use WhatsApp as a business medium, due to my mechanics fingers being too fat to work such a tiny keyboard.

Ask The Experts at K&N How To Use K&N Air Filter Oil – How Much Oil Do I use?

K&N air filter oil has been developed to remain suspended within the thousands of microscopic cotton fibers found in a K&N high-flow air filter

A typical disposable automotive air filter uses a paper filtration media efficient at trapping dust, yet they are also a significant source of airflow restriction. This is why K&N’s traditional high-flow air filters are designed with 4-6 layers of cotton gauze media pleated between a wire screen mesh. Cotton naturally breathes easier than paper which in turn increases airflow, reduces intake tract restriction, and can help your car run better. Even at home there is a very low-tech and simple way to demonstrate the advantage of K&N cotton air filters versus paper air filters. Hold a piece of notebook paper against your mouth and try taking a deep breath. You will immediately notice how much effort is required to breathe through this piece of notebook paper. Repeat the same test, only, instead of using a sheet of paper, try it again with a cotton t-shirt.

K&N lists the factory prescribed amount of K&N air filter oil for each K&N air filter on under the product specifications

No degree in engineering is required to observe how much easier cotton breathes compared to paper. Yet, K&N uses much more scientific methods of proving that K&N replacement air filters outperform their disposable equivalents. K&N Engineering performs all its airflow testing on a SuperFlow Corporation SF-1020 flow bench. The SF-1020 is a computerized flow bench capable of measuring airflow rates up to 1020 cubic feet per minute (cfm) at test pressures of up to 65 inches of water. K&N has developed procedures for measuring airflow and pressure differential (restriction) of the various size and shaped filter elements that we manufacture. These procedures are followed to ensure a consistent comparison of airflows between filters that are of differing material or manufacture.

K&N automotive replacement air filters can go up to 50,000 miles, under normal driving conditions, before cleaning and re-oiling

High airflow isn’t the only point of consideration when developing a K&N performance air filter. K&N places the utmost importance on our air filters’ dirt retention and filtration efficiencies. The secret to increased airflow without sacrificing engine protection lies in K&N’s specially designed air filter oil. K&N air filter oil has been developed to remain suspended within the thousands of microscopic cotton fibers found in a K&N high-flow air filter. K&N air filter oil acts as a tacking agent designed to grab fine particles of dirt and hold onto it until the K&N air filter is cleaned. K&N operates an in-house filtration test lab with two different testing machines built in consultation with Southwest Research Institute. K&N performs tests of filters both in the factory air box and in SAE/ISO recommended test housing fixtures. K&N’s goal is to design filters with the maximum possible airflow achievable while providing guaranteed engine protection. Our actual air filters when tested generally demonstrate a cumulative filtration efficiency of between 96% and 99%.

When using the air filter oil squeeze bottle, apply K&N air filter oil evenly along the crown of each pleat, allow the oil to wick for 20 minutes then touch up any light areas on either side of filter

Through the years there has been much debate concerning the use of air filter oil as a tacking agent on air filters. K&N isn’t the only company to use an oil treatment on its air filters. As a matter of fact, several original equipment (OE) and aftermarket disposable paper air filters use air filter oil to ensure air filtration efficiency. K&N is very aware of the "urban myth" created by a few dealerships that a vehicle's MAF sensor can be contaminated by K&N filter oil. The fact is that K&N air filter oil does not come off K&N air filters. In house testing of an over-oiled K&N air filter under extreme airflow conditions, and the use of an absolute test filter, has confirmed that no oil came off the K&N replacement air filter. Furthermore, in the last 7 years, K&N has had more than 300 actual sensors sent to us by consumers with documents showing dealerships claimed our product had caused them to fail. Microscopic, electronic, and chemical testing revealed that none of these sensors were contaminated by K&N filter oil.

If using the aerosol bottle, spray the oil evenly along the crown of each pleat holding the spray nozzle about 3" away from the filter, allow the oil to wick and touch up any light areas on either side of the filter

The oil treatment on K&N cotton gauze air filters is very small (usually less than 2 ounces) and is a critical component of K&N’s legendary air filtration technology. Once K&N filter oil is properly and evenly absorbed through the cotton, no oil will come off, even under extreme engine conditions. Most K&N air filters come pre-oiled from the factory using automated oiling machines. These machines are programmed to apply the precise amount of K&N air filter oil specific to each K&N air filter. K&N automotive replacement air filters can go up to 50,000 miles, under normal driving conditions, before air filter cleaning and re-oiling is necessary. The oversized conical air filters used on K&N performance air intake systems can go even longer, sometimes up to 100,000 miles before it’s time to service the air filter.

K&N offers two versions of the K&N Recharger air filter service kit. The two air filter service kits both contain specially formulated K&N PowerKleen degreaser and K&N air filter oil necessary to restore airflow efficiency and bring a K&N oiled cotton air filter performance to like new condition. The difference between each kit is the style of bottle used to apply the K&N air filter oil. K&N Recharger part number 99-5000 includes a 6.5 ounce aerosol can of K&N air filter oil for a quick and easy application of filter oil. K&N Recharger part number 99-5050 includes an 8 ounce squeeze bottle of oil for a clean and precise application of filter oil. Both Recharger kits work equally well, and the decision between the two is based on personal preference. However, the use of a squeeze bottle of K&N air filter oil will aid K&N users looking to more accurately measure the amount of oil applied to their filter. K&N lists the factory prescribed amount of air filter oil for each K&N air filter on under the product specifications.

K&N replacement air filters undergo multiple durability and performance tests that allow K&N the confidence to back them with a 10-year/million mile limited warranty

The actual act of re-oiling a K&N air filter is pretty simple and can be accomplished in almost no-time flat. When using the air filter oil squeeze bottle found in K&N filter cleaning kit 99-5050, apply K&N air filter oil evenly along the crown of each pleat. Allow the oil to wick for approximately 20 minutes then touch up any light areas on either side of filter until there is a uniform red color in all areas. Oiling a K&N air filter using the air filter oil aerosol spray found in K&N filter cleaning kit 99-5000 is similar to the squeeze bottle oiling. Spray the oil evenly along the crown of each pleat holding the spray nozzle about 3" away from the filter. Allow the oil to wick for approximately 20 minutes. Touch up any light areas on either side of the filter until there is a uniform red color in all areas. K&N offers air filter oil in 1/2 ounce pillow packs for small jobs up to a 5 gallon pail of air filter oil for individuals who require a large supply of K&N filter oil on hand.

K&N replacement air filters are designed and manufactured in the United States. K&N replacement air filters undergo multiple durability and performance tests that allow K&N the confidence to back them with a 10-year/million mile limited warranty. Additionally, K&N warrants that using its products will not result in a vehicle warranty denial. If you experience difficulties with a dealership repair department, K&N will step-in and resolve the issue, so you won't have to. Use the K&N search by vehicle tool to find a K&N air filter, or other performance upgrades, for your car, truck, SUV, or motorcycle. To find an authorized K&N dealer use the K&N dealer search to find a dealer in your part of the world.

 Clients comments:
Very happy with the K&N filters here at the coast with all this fine mica dust. You wouldn’t believe all the crap that comes out when washing out the filters.
I used K&N in all my cars and all my bikes in the past.  Very satisfied

If you are busy with a project vehicle for which you want a closed Air box-type intake that also makes performance, then we have:
Orion Intake system, good for over 500 Bhp
Whilst the well known Apollo is still available

We also carry a whole bunch of K&N Inline Fuel Filter & Inline Oil Filter Products


I recently received this in email form from Australia:

Public Service Announcement: BMW N47/N57 Engines

As many of you know, we have a couple of very large dogs (a Great Dane & a Bull Arab), who like to travel with us wherever we go.  To satisfy their prima-donna needs, we bought a brand new X5 30d almost exactly 5 years ago and the back seats are permanently folded down, with a furry, double mattress in the back so they can relax in to the journeys!  The car has been serviced by the supplying dealer, in line with the "smart" service indicator and has racked up close to 150k km in that time.  Anything that has worn out has been replaced without question on our part, paying full BMW dealer prices for everything, including tyres. 

Over the past few months it has developed a worrying noise, most noticeable in the morning but still there through the day.  I thought it was a propshaft or similar as it seemed to be coming from around the gearbox.  The last service was completed by a dealer in Melbourne and they had the car for 3 days.  They said yes they could hear it and it might be the timing chain but that I should just leave it for a while longer to see if it got worse and that would make it easier to diagnose.  If I wanted them to check the timing chain there and then, it would be $2500.  Yes that's right, $2.5k just to diagnose.  It was our first time using this dealer, so I thought they were having a lend and decided to get our regular dealer to check it when we returned to Qld. 

Last Monday the car was left with our regular dealer overnight so that they could hear the problem at it's worst.  They called at about 9:30 the next morning and confirmed that it was indeed the timing chain and... wait for it... it would be $10000 (count the zeros) to replace.  Even from a "prestige brand" dealer, that sounded expensive to me.  So I got on Google and YouTube to see if I could change it myself.  And that's when my hear sank. 

BMW 4 cylinder and 6 cylinder diesel engines built between 2008 & 2011 (the N47 and N57 families respectively) have a known timing chain issue.  In fact the 4 cylinder one is so bad, there is a recall in some (presumably litigious) regions but timing chain failure is very frequent with the 6 cylinder too.  By all accounts we were very lucky ours didn't let go.  The chain is at the back of the engine (so clearly not designed to be a service item) and changing it is an engine out job of 30+ hours, hence the cost. 

Now we all make mistakes but it's what happens after the mistake comes to light that determines how we feel about it.  After 18 years of continuous BMW ownership and 8 different cars in that time (only one of which cost less than 6 figures), BMW were quite happy to let us pay full price for parts (which they know to be of poor design) and full labour rate to fix the problem.  That's not what I expected.  Nor did I expect to be offered only $12k trade-in value on a 5 year old car (albeit high mileage and with trashed rear doors), when we explored the save-as-you-spend option of buying a new X5. 

Until a week ago, I would have confidently predicted to anyone who asked (and some that didn't) that we would have a BMW in our lives until we were no longer able to drive.  Today we bought a Range Rover Sport (frying pan and fire: I know!) and had the X5 towed to a local specialist who will fix it for less than $5k.  He has it down pat because he does them all the time... 

Sorry to rant but thought you might want to know what to expect if you have that age of diesel engined BMW.

I only need to think of exchanging the starter on a V8 Land cruiser petrol L
Why complicate motors to the extent that they do not even carry a dipstick anymore

Or the known oil consumption issues on:
N46N Bimmer motor- which I am porting right now.
the Toyota 3S type motors
As well as the Nikasil sleeved M52-bimmer motors, as I have transplanted into my E30 Bimmer

Gone are the days of serviceable motors.
Gooi weg en koop nuwe.
To which a friend replied:

I remember when I was in my 20’s somebody said to me that as electronics progressed those that bought the old cars for taxis etc would struggle with fixing them – often on the side of the road.  Now today we also can’t fix anything irrespective of how much we earn.  Only the dealer (or other specialist) can work out what’s going on and even then they can’t figure it out either, particularly if it has not logged an error code.

Aircraft have become the same as well.  Just change components and send them away to the specialist repair shop.  As an example the Nissan Tiida I had you could change the electric steering computer for a few hundred bucks.  The Nissan Pulsar which is essentially a remake of the Tiida you have to buy the whole steering column at about US$2800.  However the computer can still be physically unbolted and removed.  It’s just that the parts catalogue does not offer just the computer.

The further problem with all the electronics is that in a split second you can be faced with a $5000 or more bill just because one tiny electronic component inside a computer box (probably only worth a few dollars) packed up.  Disastrous when the car is a few years old and the component is worth the value of the car or more.

As a result (and luckily I am in a position to do so) I buy a new car which will give me the longest factory warranty.  Many here are 3 years with an option to purchase an extension to 6 years (about $1000 worth).  Kia offer a 7 year warranty unlimited mileage.  Many manufacturers now have capped price servicing for life (about 500 000km).  When the car passes the end of warranty I consider myself as at huge financial risk and so replace it with another new one.

The above ties in to new vehicles with a Diesel Particle Filter that does not necessarily fail, but just get's blocked by constant city driving. a new one mostly costs more than the car is worth.
Luckily we can fix this with the Unichip.
