AIRTEC Motorsport Catch Can - M2 Comp, M3 & M4

BMW S55 Oil Separator Kit for M2 Competition, M3 and M4

Protect your S55 with a proven oil catch tank solution designed for F8x platforms. This crankcase breather upgrade captures blow-by vapour before it reaches the intake tract, helping to prevent intake valve deposits on direct injection engines and keeping airflow consistent for fast road and track-day use.

The system integrates neatly in the engine bay using a CNC billet machined mounting bracket finished in anodised matt black for an OE-style look. The canister is baffled and features an internal micron filter and a dipstick level indicator. It detaches quickly for simple draining and servicing. A comprehensive hardware package and step-by-step installation guide are included for a straightforward, bolt-on fit.

Why fit an oil catch tank on an S55

• Reduces oily residue entering the intake system and inlet valves on DI engines
