What is the best paper air filter?
I can't believe some of you guys go back and forth so much about this. A different filter is not going to pick you up any more horsepower or make a difference at the track.
Go with what's easy, cheap, and simple: just get a paper Fram filter and be done with it. Leave your time worrying about power and speed to other, more important parts that you'll put on the car.

ive tried K&N, fram, purolator and stp.
and my conclusion is that as long as its paper, u cant go wrong.
and for those who wine about power increases.
its so marginal its practically unmeasurable.....
ill sacrifice 1-2hp for better filtration...

Guess im a believer that they work now.
Only real way to test that would be with both filters being 100% fresh.
Problem is, many people have run the same test you did an seen 0 gains, so there is really no solid proof that the gains are due only to the filter, just not enough consistancy in the results from test to test.
