I just got my N54 135i. Which Intercooler do you guys recomend? I was thinking of Burgers Tuning with a oil cooler also. I am thinking of also adding up some other upgrades, like,downpipes( Burger or AA?) Charge pipe(Burger) with BOV, maybe Burgers Catback exhaust. Also AA has Plasma Direct ignition coils which they sell for like a grand. My car already has a KN filter and reflash.
