Hmmm Monza aye... I pushed my previous car BF XR6T to 313rwkw with monza and other bits plus tune... I just replaced my factory BF F6 intercooler with a Monza, and the difference is very noticeable! Monza is about 30% bigger than BF F6 factory cooler and it flows twice as much.. Compared to factory BA/BF intercooler, Monza is God! Not bad for $207 from eBay!!! Free shipping included!
