AIRTEC Motorsport BMW S55 Oil Catch Can Kit / PCV Breather Tank – F87 M2 Competition, F80 M3, F82/F83 M4 GTS/CS – Direct-Fit Crankcase Ventilation Vapour Separator, Blow-By Oil Separator – ATMSBMW2

S55 PCV vapour separator and breather catch tank upgrade for M2 Competition, M3 and M4

Keep your S55 running clean and consistent with this bolt-on breather catch tank system designed for the BMW M2 Competition, M3 and M4 platforms. By controlling crankcase vapours and blow-by mist, it helps minimise valve deposit build-up found on direct-injection engines, supports reliable performance on fast road and track days, and keeps the inlet tract noticeably cleaner over time.

We have installed this unit on multiple customer cars and our own builds; feedback has been superb. The kit fits neatly in the factory bay, looks OEM-like with its black anodised bracket, and delivers the tidy, low-maintenance solution S55 owners want for long-term engine protection.

Why enthusiasts choose this catch tank on the S55

• Controls blow-by and oily vapour that would otherwise coat intake runners and charge pipes
• Helps reduce valve deposit build-up common to direct-injection petrol engines
