Contrary to popular belief the multi-piece metal mafs are prone to leaking and these one place plastic ones are not. We know of a high powered 3000GT that is running over 30 PSI on this maf without issue. It will work fine in blow through or draw through applications and will be approximately 3.5"
Will require a MAFT (we are an exclusive dealer for them and stock them) and tuning and the appropriate intercooler or intake piping modifications
