have u guys seen or felt a difference in filter choice. some people i've talked to say the sponge filters are better, and i've seen where a blitz filter has given hp gains on a supra (only filter). can u guys add anything-ity time i get a new one so help me out

 

a drop in filter provides 1-2hp at most...at times more at times less...but nothing special....ie. the cotton k&N vs. a foam monster sport, both seem to feel the same on my butt dyno...

 

IM talking for an intake...cone filter not drop in

 

Same thing...a couple of horses at most. I know DC Sports and AEM have all those fancy dyno sheets, but I doubt if you'll see 3 HP.
