I've just picked up a ST220 air box which has the 2nd air feed to it, would I notice any difference if it was fitted to a 1.8 engine ? I know the reasons why the ST220 had this design on the early models but not on the later ones.
That's what I would think, but the question has to be asked 1st before I fit. I already have a 2.3l tb on the motor as it was meant for the US focuswould imagine it'll flow better than a 1.8 one, but as you prob know, would need 2.0 maf and 2.0 tb for any benefits.

I take it, that you never seen or heard about the ST220 airbox ?pics please?
