For JDM tizightness!!!
No, actually the engine clip came that way. I do like it though, it perplexed me at 1st. But it doesnt stall at all on decell. The bov's release at slightly different pressures so you get a nice pshh accompanied by that unique HKS super sound almost like an echo. Made it a pain to make my cold air box, but I like it and I dont plan on changing it.
