in the new Honda Tuning magazine, they benchtest and dynotest a bunch of popular aftermarket intakes. they were tested for both air flow efficiency and horsepower (dyno tests were done on an RSX). the results were surprising. first of all, the AEM CAI did not place first or second! Injen came out on top, followed by DC sports! they tested about 8 different intakes. it says they were surprised when the injen boosted whp by 20 horses at the peak of the curve!! holy shit!
