Turner S54 Baffled Oil Catch Can System
Modern day emissions regulations require the use of a closed crankcase ventilation (PCV) system to recirculate combustion blow-by gases from the crankcase back in to the intake to be burned. Unfortunately, these blow by gases contain water vapor (which is a byproduct of combustion) and pick up oil mist from and the windage cloud and cam lubrication system as they travel through the crank case. Due to less than 100% effective air/oil separation in the stock PCV system, some oil mist and water vapor gets carried back to the intake tract and over time cause oil deposits in the intake manifold, intake ports, and on the back of intake valves. All will eventually lead to poor performance and reduced fuel economy, and the presence of this oil mist in the intake charge may even increase the risk of engine-damaging detonation.
With forced induction, track use, and/or extended high RPM usage, these symptoms increase as the factory PCV system is overwhelmed, and a catch can becomes a must for your E46 M3. This kit is a direct fit making this an easy reversal if desired as well as maintaining a clean appearance by utilizing the open "smuggler's compartment" on the passenger side of the engine bay.

Features:
- 6061-T6 billet machined body, anodized black for lasting protection and appearance
- Strategically positioned 4 chamber baffle system maximizes oil / air separation
- Knurled and black anodized oil dipstick makes inspecting oil volume of reservoir clean and simple
- Sealed with a pre-installed viton o-Ring
- Includes 2.5mm allen key to remove baffle plates for cleaning
- Engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can
- Closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation
- Valved drainage system - no removal of can necessary to empty
