Volumetric efficiency of an engine changes very little if at all with a K & N or other cotton media type air filters unless you have done extensive modifications to your ports, exhaust system and cam specs. Also while these oiled cotton gauze filters may "flow" a little better, then also let in more dirt and a big part of engine wear in street engines is caused by dirt particles 5 to 30 microns is size. Unless you're running a highly modified engine or one with forced induction, then all an aftermarket oil-type filter is going to do your stock motor is cause slightly faster cylinder wall wear.

 

Yes, I am aware but that would probably mean that the engine would need work at 200k instead of 300k or so, I don't intend to keep the car that long anyways, so till the time its with me, I should be good

 

I've seen engines which used crap low restriction filters ruin the engine bearings in as little as fifty to sixty thousand miles. Like it or don't, for a daily driver there really is no replacement for an OEM spec air filter.

 

^So far I've run the K&N filter for at least 160K miles.

 

Louisville, KY doesn't exactly qualify as a dusty environment; you could probably do as well with no airfilter at all.

 

Its not a daily driver but it is my only car.

If not the Typhoon, I would surely go for stock replacement filter from K&N. Have had a good experience before with a K&N replacement filter on a much smaller car & in a much Dusty environment.

 

How do you know you had a good experience with your previous K&N; did you have your oil analyzed before and after you started using it so you can confirm contaminates like silicone (aka. sand) remained low?

 

I love your F4U Corsair, it's my favorite aircraft of all time.

 

Thanks, mine too.

 

Its THE most important filter on the the whole car, dont go cheap. I'd buy from Honda.
