[1]Close your eyes, and picture an aftermarket performance air filter. Chances are it’s made from red oiled cotton gauze and has K&N [2] stamped on it. Whether it’s a round filter for a carbed setup, a barrel filter for EFI, or a complete performance intake system, chances are it’s in the K&N catalog. One thing that you might not fully appreciate, though, is what else the K&N engineering staff is up to when they’re not coming up with new applications for their familiar air filter technology.
K&N is a company staffed by enthusiasts, and it’s clear from all the cool stuff sitting around their booth at this year’s PRI show that when somebody has a good idea for something they should make, it doesn’t get round-filed. A perfect example are oil filters – you’ve probably seen K&N’s premium disposable spin-on filters with their heavy-gauge white shell and trademark wrench nut on the end. Not content to leave well enough alone, they’ve come up with new oil filter designs that add both features and value.
Shown above is their reusable spin on filter that is perfect for racers (or even street enthusiasts) looking for an oil filter they can disassemble and inspect. If you’ve ever cut open a conventional disposable spin on filter to check for contaminants or bearing shell wear, you know it’s an unpleasant process. This new design makes that task considerably easier while also offering outstanding filtration.

Another thing you may have noticed upon cutting open an auto parts store (or even OEM) oil filter is that they’re often questionably designed and constructed with components like glued cardboard end caps and iffy drainback valves. Even well known brands suffer these cost-cutting flaws, and while the existing white K&N oil filter is better in every respect than these cheapies, it comes at a price. While racers will have no problem seeing that a top-quality $15 oil filter is cheap insurance in protecting their investment, for some reason people will buy a $50,000 new car but not want to spend more than $7-$8 for a filter.

It’s K&N to the rescue for the “value conscious” DIY’er, with their new line of inexpensive oil filters, which feature quality internal construction and materials at a suggested retail price that makes them competitive with lesser brands. That’s just the way they roll at K&N – Better ideas brought to market all the time.
