K & N air filter

[w261w261]

I've run a K&N filter for a few years in an '89 Honda, and have experienced no problems. However, recently I did send off an oil sample to one of the analysis companies, and the report came back that the oil had an unusually high level of silica. I'm thinking that the filter is not working as well as the standard paper filter, and that I'm not doing my engine any favors by leaving in the K&N. I'll send off another sample to see, and then if it's high, go back to paper, then send a 3rd and see if the silica has come down.

The late 80's Honda engines are famous for going 3 or 400k. Mine has 225k, and I'd hate to think I'm compromising it for the sake of a couple of extra hp.

And if you look @ the dyno numbers, in most cases the horsepower gains from air filters like that are usually AFTER your peak HP, so they're pretty much useless. Just some numbers to make the Johnny Andretti Eclipse/Civic owners think that $100 "cold air" intake, $80 fart pipe and $120 Erector set wing really make their car faster
