Check out the E90Post forums but I highly recommend Active Autowerke and Riss Racing for performance upgrades. We have a full performance section on our website just for the 335. You will want to consider the aFe Dual Cone Air Intake as well as the Active Autowerke Blow Off Valve, Active Autowerke Proceed Software, Active Autowerke Exhaust and Riss Racing Down pipes.
