The BMW N63 rear cover is a metal plate that covers the rear of the BMW N63 V8 engine. It helps to seal the engine and prevent oil leaks. Over time, the original sealing gasket becomes brittle and does not seal, causing leaks between the engine and transmission bell housing. This repair can be very expensive and is usually misdiagnosed for a rear main seal. The AGA Updated N63 Rear Cover is an inexpensive alternative, made of 6061 billet aluminum. This kit includes the rear cover, viton o-ring, alcohol wipe, scotch-brite pad and o-ring grease. BMW Part # 11142446298 & 11148483799 BMW Service Bulletin (SIB) 11 09 16

For engine builders pushing the absolute limits of high-performance engineering, the ARP Custom Age 625+ Cylinder Head Stud Kit represents the pinnacle of fastening technology. While standard aircraft-quality steels and even the renowned ARP2000 alloy are impressive, the proprietary Custom Age 625+ super-alloy provides a massive leap in capability by increasing tensile strength by an additional 40,000 to 60,000 psi. This specialized hardware is engineered specifically for ultra-high-boost applications, offering superior fatigue resistance and the unique ability to maintain its structural integrity under extreme temperatures that would cause lesser materials to weaken.
