"A note from the author:
The reason I started this crusade was that I was seeing people spend a lot of money on aftermarket filters based on the word of a salesperson or based on the misleading, incomplete or outright deceiving information printed on boxes and in sales literature. Gentlemen and Ladies, marketing and the lure of profit is VERY POWERFUL! It is amazing how many people believe that better airflow = more power! Unless you have modifications out the wazoo, a more porous filter will just dirty your oil! Some will say, I have used aftermarket brand X for XXX # years with no problems. The PROBLEM is you spent a chunk of change on a product that not only DID NOT increase your horsepower, but also let in a lot of dirt while doing it! Now how much is a lot? ANY MORE THAN NECESSARY is TOO MUCH!"
By the way, I'm not on one or the other side of the argument, but I'm not sure if enough dust/dirt is accumulated over the lifetime of a street car to justify using the paper filter over the lifetime filter, however, oems do put the paper filters in for a reason.
