The ARM Motorsports S55 Oil Catch Can is engineered to prevent harmful oil vapors from entering your engine’s intake system, protecting performance and long-term reliability. Equipped with a precision double-baffled filtration system, it efficiently separates oil particles from PCV air before they can accumulate in the charge piping, intercooler, or intake valves. This maintains cleaner airflow, promotes healthier VANOS operation, and helps sustain effective octane levels—especially valuable on tuned or high-boost S55 applications.

Designed specifically for the S55 engine, this system installs without cutting or modifying any factory PCV lines, maintaining full closed-loop functionality. The stealth-mounted design integrates seamlessly into the engine bay, offering a discreet yet highly effective solution.

Constructed from CNC-machined T606 aluminum and anodized in Stealth Black, the catch can offers exceptional durability and heat resistance. The kit includes 6-layer reinforced hoses for long-term reliability. Maintenance is simple and quick: just unscrew the bottom of the canister or use the drain plug during routine oil service intervals.

The ARM S55 Oil Catch Can is a fully bolt-on upgrade, delivering clean and efficient engine operation while preserving OEM-like fitment and appearance.
