Re: KandN=Bad For Engine??
It seems to me that a good paper filter works better, but K&N filters are effective at increasing air flow. I have used them for many years.
They do wear out, after many cleanings, the cotton fibers seem to open up and have larger 'holes' between them. I have had 3 Chevy 2.8 V6 engines, and a friend had one. Using paper filters we got between 265,000 to 411,000 km with the engines running fine.
My one K&N filter equipped 2.8 V6 (since 1988) got 110,000 km before the cylinder walls showed such drastic wear, it needed a rebuild with an .80 rebore to clean up the wear. The only real difference was the air filter.
