I have a blitz SUS induction kit, ive got a 6" cold air feed going to it though. Its in the original location but the cold air feed helps alot. i have it located underneath the radiator so some nice cold air flow. Ive heard the a'pexi and its a bit too "roar'ish" for me..The blitz filter screams at higher revs and sounds insane.Plus i cant be hassled with cotton types any more , the last one i had, had a hole appear in it somehow?! and well yeah, you can guess what kinda problems that led to.
