Nick’s Racing on air filters, performance and biltong

K&N ’s are still the world leaders

Most people buy K&N air filters because they are very effective at retaining dust. You need to ill-treat them to get them to pass dust, such as over oiling. Ill-treating anything will make it fail. “Fit it and forget it” is the motto. On a farm it should last 50 000 to 100 000 km’s before cleaning, and it has a 1 million miles warranty.

Think about it the next time you want to fit an air filter to your bakkie, quad, stationary engine, welder, genset… Nick’s Racing not only stock K&N air filters, but also carry K&N oil filters for motorbikes and quads as well as in-line oil and fuel filters.

 

Look out for counterfeit filters

Lately, we have run into the problem of counterfeit K&N’s being sold. The packaging looks nearly identical to the genuine product. The part number is different though. The filter is poorly made. So, if you suspect you have a counterfeit K&N, you can bring it to Nick’s Racing for inspection.

There are a lot of filters out there that get sold as “K&N ”, which are definitely not that!

If it does not say K&N on the packaging and filter, then it is a cheap knock off. You need to decide what is better; a genuine K&N or an engine rebuild.

 

Clamp-on or replacement unit

A lot of people are buying clamp-on filters, as they give the engine a rorty sound, are easy to fit and usually cost under N$500. These you would fit on stationary engines and  pipe-cars. Though on most modern vehicles the stock airbox is well designed to get loads of clean air, giving you the most power. Here you remove the stock air filter element and in goes the K&N replacement unit, costing about N$750. Cheap if you consider it is the last filter you will ever buy. Plus you need not worry about the dealer having an issue with it, as K&N guarantees the filter to exceed all manufacturers’ specifications.

 

Benefits of K&N over stock air filter

The K&N cotton high-flow air filter is somewhat more complex then a disposable paper air filter or a typical foam air filter. The unique design of the K&N air filter features multiple layers of oiled cotton fabric which captures the airborne dirt particles. These dirt particles cling to the fibers of the filter and actually become part of the filtering media. This process, known as depth loading, allows the K&N air filter to retain significantly more dirt per square inch than a paper filter. The cotton fabric is sandwiched between pleated aluminum screen. Pleating increases surface area which in turn prolongs service intervals. Pleating exposes substantially more surface area compared to a flat element like foam.

 

The dirt particles collected on the surface of a K&N element have little effect on air flow during much of its service life because there are no small holes to clog. Particles are stopped by layers of crisscrossed cotton fibers and held in suspension by the oil. As the filter begins to collect debris, an additional form of filter action begins to take place because air must first pass through the dirt particles trapped on the surface. That means a K&N air filter continues to exhibit high air flow throughout the life of the filter while it is accumulating dirt. At the same time, the air flow for an average paper air filter can decrease dramatically as the paper element gets dirty. So as dirt accumulates, the performance advantages of a K&N air filter can increase! Tests performed by an independent laboratory commonly known as the Frazier Permeability Test have shown that the Medium used in K&N air filters flows more than 300% more air than paper air filter medium when compared on a square inch per square inch basis. So, be assured a K&N air filter will provide dramatically more air flow which can enhance engine performance and decrease fuel consumption.

 

Committed to performance

In the last 12 months we have tuned over 300 cars, successfully. Since nobody took me on, my “money back guarantee” it must have been successful. I treat your car, as if it was my own. And I drive my car for 20 years or so.

 

After having run 1000’s of cars on my Dyno over the past 10 years, I recently had the rotating assembly overhauled and balanced. A Dyno only measures power, as a torque wrench only measures torque. With further instrumentation, such as exhaust gas analysers, boost gauges etc., we can set-up nearly any diesel or petrol engine to perform at its optimum efficiency.

 

Unichip tuning

I often get asked what the Unichip advantage is over flash-tuning or other software upgrades. Firstly we tune your car on our Dyno. Looking at every car as an individual entity to be set-up perfectly.

A Unichip can be removed. This comes in handy if you want to do fault-finding or have bought another vehicle where you might want your old Uni-Q to be fitted to.

Considering that you will not only pick up power and throttle response, but also a reduction in fuel consumption making a tune pay for itself! An engine set up for maximum efficiency should also last longer than one in a bad state of tune.

 

Quite a few customers opt for a stage 2 conversion (K&N, Unichip, tuned-header free flow exhaust) on their new vehicles. These we can make soft for hunting cars or give a rumble vir die spog motors. Head-porting and cam grinding is less asked for these days.

 

Brakes and suspension

All this ties in well with our HD brake kits that not only last longer, but also significantly enhance brake performance. The same company also manufacturers the top DAKAR and other race vehicles. If you load your vehicle heavily, you will appreciate the enhanced stopping power.

 

We have also been selling and installing suspension systems and snorkels from Iron Man for the past 10+ years. Even longer than that we have represented Camil coil over shock absorber systems, which greatly enhance gravel-road driving.

 

Since we do all the work ourselves, as well as direct importing, we can offer realistic prices. I believe in value for money. This is far removed from goedkoop!

 

Other lines of interest

As some of you might know, Nick is fond of being outdoors, one of the main reasons he returned from overseas in 1993. Therefore he has added a lot of items to his selling list, that fall outside the realm of tuning.

 

Everything we do is aimed at the utility market where things have to be tough to survive.

Take our free flow exhausts that are made from 2mm wall-thickness boiler tubing, to our MileMarker hydraulic winches. MileMarker hydraulic winches compare well in price with their US-made electric winches, whilst being far more reliable and quieter.

LightForce spotlights shine further whilst being close to unbreakable. These performance lights come in handy when driving at night on our roads frequented by animals.

 

Nick’s Racing also stocks rifle scopes and kitchen knives in steel and ceramic. These are not high end fancy units, but tools for the working man who has an affinity to biltong. Much more can be found on www.nicksracing.com
