Upgraded valves designed for high horsepower applications! Our valves are not finished from generic blanks rather they are specifically designed for each and every application. We work relentlessly, testing and researching every aspect trying to improve the air flow of our designs. With every valve design, we strive to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc. It’s unlikely you will find any of our competitor’s valves with stricter dimensional tolerances than our Supertech valves. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere! Optimum high flow rates are achieved by ensuring that our valves are manufactured with the best angles for each application. We consider back cut, under cut and valve head angles for each application to produce the optimum high flow rates for each application. In 2006 we introduced our stem Superfinishing as a standard addition to all of our valves at no additional cost. When our Superfinish is combined with our Black Nitrided valve, it reduces the surface roughness to 1/3 of our chrome coated valve. The end result… unsurpassed performance and durability. Our exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for greater strength at higher temperatures. Black Nitride Coating: This is a hardening treatment that has been steadily growing in popularity over the last several years. These black Nitride coated valves feature harder surfaces and smoother finishes, providing less friction and subsequently longer life. Please see below for more benefits of our Black Nitride valves. Black Nitride Coating Head Diam: 30.50mm Material: Black Nitride Groove Type: Triple Groove Length: 105.65mm Stem Diam: 5.95mm Size: Std

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. 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. Photos of installed baffle for reference.

The S54 is an incredible feat of engineering. Smooth power delivery, individual throttle bodies, and an 8,000 rpm redline make for an unforgettable driving experience. As with any BMW, maintaining optimal oil temperatures is key to extending the life of your vehicle and ensuring that you're getting an unparalleled driving experience. As many of these vehicles see frequent track time, the team at Mishimoto decided to develop a performance oil cooler kit that would provide improved durability and deliver the power needed for track driving. The result: an extremely efficient core with a proven 30°F (16.7°C) drop in oil temperature. With an increase in core thickness of 110%, this oil cooler kit raises your oil capacity by 0.44 qt. The oil cooler end tanks, cast from a single piece of aluminum and TIG-welded to the core, have been designed for maximum reliability, giving you the confidence you need to push your E46 M3 to the limits.
