PRODUCT DESCRIPTION
COMPATIBILITY: 2000-2006 BMW E46 M3 (LHD only) & 2003-2004 BMW E46 M3 CSL (LHD only). GENERAL INFORMATION: The oil catch can mounts to the right hand engine compartment near the firewall. Therefore, it is not compatible with right hand drive models. It is compatible with early models where the ABS module is mounted in this compartment. It is also compatible with later models which feature a secondary PCV system.
Radium Engineering's closed-loop system does NOT vent-to-atmosphere (VTA), so it is emissions compliant and track legal. Instead, clean, filtered air is routed back into the engine for combustion and to promote negative crankcase pressure which optimizes performance. Furthermore, a closed system prevents unwanted oil vapors from entering the cabin. FEATURES: - Effectively raises fuel octane and increases performance with cleaner inlet air. - Prevents oil buildup in the throttle body, intake tract, manifold, etc. - Excessive oil accumulation can signify a damaged engine. - Stainless steel filter media is washable and re-useable. - Reduces hydrocarbon emissions. - Capacity: 200mL (7 fluid ounces). - Height (without fittings): 12.7cm (5 inches). - Outside Diameter: 6.2cm (2.45 inches).
