The ZERONINE DESIGN oil catch can kit for the Mk8/8.5 Fiesta ST and Puma ST, is an extensively developed system that helps ensure your direct-injection engine is working at peak efficiency, helping to remove any unburnt oil vapour from the intake system, preventing build-up on valves and ensuring efficient combustion.

The complete kit requires no drilling, is fully serviceable and uses pre-formed plastic lines with OE-style connectors, for quick and easy installation.

Features and Benefits:

Reduces oil vapour entering the intake: Less oily residue means reduced intake sludge, keeping the throttle body, MAP sensor, and intercooler cores cleaner for years.

Slows intake-valve carbon build-up (DI engines don’t wash the valves with fuel): Maintains smoother idle and more stable low-rpm response as deposits accumulate more slowly and improves airflow and compression efficiency.

Lowers knock tendency from oil vapour in the combustion mix: More stable ignition timing (less knock correction) can make the car feel sharper in hot weather or on track. Reduced detonation events protect pistons, rings, and spark plugs, supporting consistent power over the life of the engine.

Reduces oil contamination and dilution pathways: Less blow-by oil recirculated into the intake means fewer fuel-rich, sooty deposits, which helps keep the PCV tract healthier.
