I learned all about intakes with hondas...they dont really do squat. It made my honda cars louder when you mash the gas...In fact I always ran stock airboxs when possible but with my last engine swap the stock aib box inlet tube was to small for the throttle body so I had to use a cai...I painted black so I didnt get the "ricer bling" Im sure you gain a few hp but honestly on a stock engine it usualy doesnt make 1/4 times much different in my expierences....id rather spend money on a of road h pipe sinces its about the same price as a good H pipe
