Automotive → Re: K&N Air Filter

This subject is usually a big can of worms because there are people very strongly on each side. Some are convinced they'll destroy an engine due to particulates they let pass; others are just as sure it'll add 40 horsepower to their Civic.

I have used them for 20 years now. I like them for their serviceability - wash, re-oil, re-install. I think they are more useful on forced-induction cars than naturally aspirated engines when it comes to power gains.

My cars have ranged from 130 horsepower to 500+ and they all did well with K&N. I like them enough that I'll continue to use them in any vehicle I get in the future.

Wait a second. You mean it didn't give me a 25% horsepower increase?

Only if you paired it with at least 2 stickers.

Too bad they only include one with the package, I had to get my second sticker used.

Heh heh -- I practiced this psychology in reverse. I put the K&N sticker on the side hatch window of my stock-appearing Dodge Stealth. I hoped that its presence would make others assume that was all I knew about performance.

The drawer full of 12.5 sec quarter mile time slips proved otherwise. I did my best to make it a sleeper
