Yeah it ain't cheap. I'd probably keep the stock airbox setup otherwise go with the Stillen. Skip the Z1 plenum, you'll not see any gains down low or i the midrange.

 

So question, with the jet cam set up, will it throw any codes or cause you to fail inspection? Since you will have to get a tune, like say either uprev or ecteck, what issue come with passing inspection. I have camed a few honda motors and you are not passing inspection with hondata lmao.
