Anyone with a modified N55/S55 knows the risks involved with the OEM Crank Hub. When the engine simply can't handle the stresses its put under or the design is such that it simply does not support extreme conditions, issues can arise. Under certain conditions, the N55/S55 crank hub likes to spin, without warning and even when the engine is in perfect health. MMR has produced a EN36 machined billet one-piece crank hub heat treated with a 0.75mm case hardening which makes it extremely durable. Due to the one-piece design, it ensures that the friction plates cannot slip. This offers a huge jump in reliability when paired with a new properly torques crank bolt. Installation is requires no drilling or modification to the OEM crankshaft ensuring a perfect fit! Included in this kit is MMR's T-6061 machined billet aluminum capture plate anodized in their trademark finish. The MMR Performance capture plate secures the head of the OE crank bolt and prevents it from turning or being able to loosen. *Installation recommended by a professional shop or technician.

MMX's high-flow charge pipe kit includes everything needed to improve the performance, reliability, and aesthetics of your N55-powered E8x/E9x. Smooth bore pipework improves airflow over stock and due to reducing deformation of the hoses under load or vacuum, the MMR charge pipes also improve throttle response and power output. Increased boost pressure can cause the stock pipework to split or crack and cause drivability issues. MMR's charge pipes are made of lightweight aluminum which fit right in place of OEM charge pipes. Includes a 1/8” bung for easy addition of either methanol or water injection. Features: Replacement high-flow aluminum charge pipe with CNC leak-free connection Silicone coupler hose and two stub hoses Replacement c-clip Jubilee clips o-ring

Both the N55 and S55 engines are plagued by the same issue when chasing high horsepower numbers... the dreaded crankhub failure. Fortunately MMR Performance has released an upgraded version of their already stout single-piece crankhub, but this time offering a 4-pin dowelled location that locks onto the front of the crankshaft. This configuration eliminates the multi-piece crankhub with friction discs in favor of a more robust single piece crankhub. Recommended for high-powered cars over 700 Horsepower

N54 and N55 powered BMW's are infamous for their accessibility to easy power gains, and addressing the amount of heat that the engine puts out goes hand in hand towards reaching those numbers. MMX's Performance intercooler is a step up from the stock intercooler which now delivers even better cooling and provides rom for more power to the wheels. This intercooler possesses a larger core and more surface area than the stock intercooler which both reduces pressure drop and improves cooling. This results in a 20ºC temp drop for the intake and about a 20bhp increase to the wheels. This is a direct replacement for the factory intercooler and fully reversible. All required hardware is included. Precision TIG-welded throughout 20%+ larger core volume Efficient bar and plate core Typical intake temperature reduction of 20ºC over OE Increases power and torque, even with standard boost pressure OE-style charge pipe connections for easy installation Anti-corrosive thermal black finish MMR logo Can be installed in under an hour
