Wagner Tuning BMW N55 EVO2 Competition Intercooler (FMIC) & 200 CPI Catted Downpipe Package - F20/F21 M135i, F30/F31/F34 335i (2012-06/2013 PWG), F32/F33 435i (from 06/2013)

Serious cooling and freer-flowing exhaust in one proven bundle for early F-series N55. This charge air cooler upgrade paired with a 200 cell sports cat downpipe gives lower intake temps, reduced exhaust restriction, stronger mid-range and repeatable performance on fast road and track. Ideal hardware for remapped Stage 1 and Stage 2 N55 cars looking for a reliable bolt-on solution that keeps OEM-style fit and finish.

We have fitted this package in-house and on customer vehicles, and the feedback is consistently positive. Intake temperatures drop quickly compared with the factory setup, throttle response feels sharper and the car pulls harder through the revs. If you want a durable front mount cooler and a high-flow catalytic downpipe you can trust, this is the combo our customers come back for.

Why this bundle stands out

• Large stepped performance core for excellent heat rejection and stable intake air temps
• 200 cell metallic sport catalyst reduces exhaust back pressure for more usable torque
