ECS Tuning N55 Baffled Oil Catch Can Kit for BMW F30 3 Series 335i/335i xDrive (2012-2015, 3.0L N55) - PCV Oil Separator, Billet, OE-Style Mount

Keep your N55 running cleaner for longer

Cut down on blow-by and keep oil mist out of your intake with this premium, multi-stage baffled catch tank designed specifically for the BMW F30 3 Series 335i and 335i xDrive with the turbocharged 3.0 straight-six. This crankcase breather upgrade helps reduce intake valve contamination on direct-injection engines, supports consistent performance, and gives your engine bay a tidy, factory-style finish.

We have run this setup on our own cars and customers love the results. Fit and finish are superb, the installation looks OEM, and the canister actually traps oil vapour and moisture rather than sending it back through the intake tract. Daily drivers and mapped cars alike benefit from cleaner charge pipes, a fresher intercooler core, and less oily residue in the turbo inlet.

Why enthusiasts choose this oil mist separator

• Helps slow carbon build-up on intake valves on direct-injection N55 engines
• Captures vapour and condensation from the crankcase ventilation system before it reaches the intake
• Keeps charge pipes, intercooler and throttle body cleaner for longer
• Assists cold weather protection by collecting moisture that can otherwise freeze
• Supports stable performance on stock and tuned vehicles

Engineered for efficiency and serviceability

• Multi-chamber internal baffle design that forces several direction changes to drop oil droplets out of suspension
• Integrated knurled dipstick for quick level checks
• Fully rebuildable body with removable plates for easy cleaning using the included 2.5 mm Allen key
• -10AN ORB ports for secure, leak resistant connections
• CNC machined 6061-T6 aluminium canister with black anodised finish
