The VAC Motorsports Crank Seal Guard, made of 6061 Billet Aluminum, prevents your serpentine belt from being pulled into your engine, a common problem amongst BMW N54, N55, and S55 Engines. Without a crank seal guard, the serpentine belt on N54, N55, and S55 engines is commonly sucked into the crank hub area past the crank seal, where it enters your engine and disrupts engine timing. When this occurs, the belt is shredded and clogs engine oil pickup, starving the engine and reducing oil pressure, causing catastrophic engine failure and thousands of dollars worth of damage. VAC Motorsports’ Crank Seal Guards are precision machined for perfect fitment and provide rigidity and maximum protection. We designed our guard with self-locating pilots to perfectly seal the crank hub bore and provide even, minimum clearance around the crank hub. Installation Hardware included. Made in the USA.

The crankshaft position sensor transmits the crankshaft's position to the computer. This helps the computer to calculate proper spark and fuel control. If you're struggling with CELs, hard starts or no starts, stalling, and/or a rough idle, you may need to replace the crank position sensor.

The camshaft position sensor communicates the position of the camshaft to the computer. This helps the computer to calculate proper spark and fuel control. If you're struggling with CELs, hard starts or no starts, stalling, and/or a rough idle, you may need to replace the cam position sensor.

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code, but not always a check engine light. A misfire code may be related to an ignition coil, but could be from other things as well. ometimes, a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.
