Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. When you’re racing with an M54 and you want to control oil burn, installing an external catch tank is a great way to do it. The stock oil separator allows oil into the intake at sustained high RPM. This causes the intake runners, piping, and throttle body to be contaminated with oil and carbon build up. Excessive carbon build-up on valves, piston crowns, combustion chambers and spark plugs. This also increases the chance of detonation and power loss. Includes all hardware and parts to make installation easy!

In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. AAF's own M54 E46 Oil Pan Baffle. Under racing and track conditions, oil can move in the oil pan enough to cause extended moments of oil starvation. This can cause premature, and in some cases immediate, engine failure. This baffle keeps the oil at the pick up better than others on the market. This pan features a tight fit with an extra tab on the front to keep oil from exiting under braking. Six gated holes control oil slosh in the sump. A must have for all track cars. Features and Benefits Track-proven to prevent oil starvation Directional trap door baffling completely that closes off the oil pump pickup for maximum protection against oil starvation during turning or acceleration Baffle plate with drain-back slots help accelerate return of oil to the bottom of the sump while also preventing oil slosh and reducing oil consumption Reduces the risk of oil starvation when oil levels are low Works with the factory cast aluminum oil pan, which is considered a structural member of the engine block and is less prone to failure or leaking than aftermarket sheet metal pans Light-weight aluminum construction Made In the USA **Note: Requires welding to install.
