I just picked up a CP products air intake for my 98 EX. It is your typical polished tube but has the stainless-steel filter instead of the K&N style or foam filter. I've always used K&Ns on my previous cars, but got a good deal on the CP.

Are these any good? Are they crap? How do the filtration levels compare to a K&N-stlye filter? I know that an intake is an intake (unless hooked up to a turbo/supercharger), but I just wanted to make sure that these aren't going to hurt engine performane.

 

Most intakes use like a cotton gauze that is saturated with oil. This is how the intake gets most out of the filtration by using the oil so that little particles stick to it.

Then there is the foam type like weapon-r. Not sure if the same method is used. I don't think that oil is involved with those filters.

If you still have your older K&N filter, couldn't you just use that filter on the piping of the CP?

 

I have a foam filter from Jackson Racing. It is a biatch finding cleaner and oil for it.

 

my filter fell off my CAI,and i ran it over.
