just installed the hps tube to my stock box, must say..... i was effin pissed when it didnt fit!:cornmad: tube was about half inch too long! had to cut it, now the side for the air box looks like sh**. after all was finnished, i am impressed with the overall outcome paired with a kn filter. smoother acceleration, louder throttle growl n vtec:vtec:. guess ill have to get used to the fact the tube looks bad.
