I would say it is pretty accurate.

I'm getting the BLITZ SUS intake system on my car... they run like $235.00! They claim 13HP? On which car?

That test kinda makes me wanna buy the Apex'i filter...

cool... I guess I shoulda read the whole article instead of just skimming, huh?

Man that megaflow filter sucks.Oh,and the test seems to be fair & accurate.

K&N IS PROBABLY THE MOST RELIABLE, i think, theyre american made, and all the v8 heads use em, and trust me, its not for no reason, its cause they know

to be fair all the makes have lots of experience and also perform well in numerous race categories so all companies have proper research like it says in the article its probably all down to preference.
