HKS or K&N drop in filter?

At $15-$20 a pop it doesn't take long to overcome the price of the K&N.

Oh yeah, I don't have the info handy but there have been several studies and comparos made of the K&N and other filters vs. the stock filter in many cars. I remember the results were clearly in favor of the stock or other similar paper filters as far as filtration and flow as long as they are replaced as needed. For sure they are hella cheaper than the K&N plus the oil and cleaning kits, etc. I've tried the K&N and it did not work well for me. YMMV, etc.

The stock filter does not flow well at all, but if you can show me proof, I'd gladly take heed. K&N has had a much higher flower capacity than stock filters for many years on many cars. Are you saying the stock OEM Evo filter is suddenly better than any stock filter before?

filter.However, air flow is not the only factor to consider when choosing an air filter. Looking into the more important factor which is effective filtration and longevity (time between replacing/cleaning filters) there is an interesting article to look at.

Very interesting............

I've got the works filter. Didn't feel any real hp difference, but crisper throttle response is definately appearent. all in all a good replacement @ 9000 miles of city driving. More surface area generally means more air flow.
