Wagner Tuning BMW F-Series N20 EVO2 Competition Intercooler & Decat/Catless Downpipe Package - F20 F21 F22 F23 F30 F31 F34 F32 F33 (125i 220i 228i 320i 328i 420i 428i) Stage 1 & 2 FMIC Kit

Unlock real-world N20 performance with a proven cooling and flow bundle

Looking to sharpen throttle response, control intake air temperatures and free up exhaust flow on your BMW 2.0 turbo petrol? This carefully matched Wagner Tuning upgrade package delivers exactly that. Pairing a high-efficiency front mount charge air cooler with a free-flow cat-delete front pipe, it is a brilliant foundation for remapped cars and a strong upgrade on stock hardware too. Ideal for tuned Stage 1 or Stage 2 setups on F-series 125i, 220i, 228i, 320i, 328i, 420i and 428i models including xDrive variants.

At MJ Modifications we have installed this kit on customer cars and the feedback is consistently positive for cooler IATs, faster spool, repeatable performance and improved driveability in both daily use and hard driving. If you want a bolt-on FMIC and de-cat front pipe combo that works, this is the one.

• Quality Wagner construction and OEM-like fit for a straightforward install
