I live in michigan so no emission test's or nothing...and my engine bay is so clutered yuck!! i want to remove everything i dont need i want ps and ac though, what all can be removed? egr valve? i was told it could be blocked off with a plate?? my air pump i want out ...it has a o/r h on it...i did not install so im guessing the one end at that pipe is probley already blocked off...what else can come out to get the cluter out?
