AIRTEC Motorsport Twin Oil Catch Can/Catch Tank & Oil Separator Kit + CNC Billet PCV Baffle Plate for Ford Focus RS Mk3 2.3 EcoBoost (2016-2018) & Focus ST Mk3 2.0 EcoBoost (2012-2018) - Crankcase Breather Upgrade - UK Made

AIRTEC Motorsport Dual Catch Tank and Crankcase Vent System for Focus RS Mk3 and Focus ST Mk3

Keep your turbo Ford running crisp and clean with this UK engineered oil separator and ventilation upgrade. AIRTEC’s CNC machined alloy replacement plate and twin external catch tanks help manage blow-by, reduce oil mist entering the intake path and keep valve deposits to a minimum on both tuned and standard cars. Ideal for fast road and track use, it is a proven way to protect your 2.3 turbo RS Mk3 and 2.0 turbo ST Mk3 from oily build-up and inconsistency caused by crankcase vapours.

What makes it a must-have

• Precision CNC aluminium baffle plate replaces the factory cover with an improved internal labyrinth to separate vapour more effectively
• Twin external catch tanks give the crankcase an easier route to breathe, which helps limit oil carryover into boost pipes and inlet tracts
• Cleaner intake plumbing and manifold, which supports consistent performance and helps reduce carbon on direct injection valves
• Anodised tanks include dipsticks for quick checks, so maintenance is simple
• Quality fittings and correctly sized pre-cut hose for a tidy, reliable installation
• Smart anodised finish with the AIRTEC logo for an OEM plus look

Why enthusiasts choose this setup

The standard system can let oily vapour coat pipework, intercooler cores and inlet valves. Over time that residue can hurt throttle response and long-term efficiency. This upgrade separates and stores the oil in dedicated tanks, keeping the intake path cleaner and helping the engine breathe properly. It is a cost-effective preventative measure that supports stable performance on spirited drives and track days.
