Batteries

Is your BMW slow to crank or suffering from other electric issues? Oftentimes it is as simple as replacing the battery. Additionally, we have all other battery related components available if you need replacements.

Camshafts

BMW engines are tuned for top-end power - over 4,500 RPM. If you want to maximize the power available you need to change the camshafts. We offer only high quality brands of camshafts, including Schrick and Catcams. Schrick is a German performance cam manufacturer renowned for their camshaft tuning and engineering. These are top-of-the-line camshafts from a supplier to some of the world's top automotive brands. AVL-Schrick provides tuning and prototyping to some of the most potent and exclusive performance cars in the world and they have long been the source for BMW performance cams. Installing higher lift/longer duration cams improves engine breathing at higher RPM ranges. By opening the valves faster and for longer periods of time you can let more air in. With the proper fuel and timing you can gain a lot more horsepower. Special tuning and setup is generally required to take advantage of the new dynamics. Schrick cams are direct replacements for the stock cams and usually bolt-in with no additional modification or parts required. In some cases, valvetrain upgrades such as springs and retainers are recommended. Turner Motorsport is a direct Schrick distributor for the North American market.

Cam Sprockets & Gears

Prior to the use of the VANOS self-adjusting cam sprockets all BMWs used a fixed cam sprocket/gear and in some cases, performance versions were available to retard or advance timing depending on the need. We offer factory BMW cam gear upgrades as well as our own adjustable units for proper setup and dialing in of intake and exhaust cams.

Crankcase Vent, PCV, and Oil Separator Systems

Every car has a crankcase vent system that is supposed to suppress oil from making it into the intake ports and combustion chamber. A good functioning system will separate oil from the atmosphere and return it to the oil pan (or collect it in a catch can) while allowing the leftover vapors to burn in the combustion chamber or recirculate through the system. This has always been known as a PCV system (Positive Crankcase Ventilation) but BMW has several other names for it - oil separator, crankcase vent (CCV), and cyclonic separator. Failures in the system will allow raw oil to enter the intake and eventually into the engine itself which can have disastrous effects on engine performance and longevity. As emissions regulations on oil and gas venting have gotten more stringent the PCV systems have gotten more complex and failure prone. And because the CCV is intertwined with other systems you could have rough running, loss of power, higher oil consumption, misfiring, stalling, or other annoying issues. There is no replacement interval for these so we recommend inspecting your crankcase vent system as part of your regular maintenance routines. Symptoms of a bad crankcase vent are: whitish or yellowish film on the underside of the oil cap, whistling/squealing noises (not caused by a belt), suction on the oil cap that makes it hard to unscrew, large amounts of white smoke from the exhaust, and excessive oil consumption.

Cylinder Head Parts & Head Bolts

Cylinder head parts include all of the pieces of the valvetrain, lifters, rocker arms, head studs, and head bolts. We sell the original BMW or OEM head parts as well as performance upgrades such as titanium valve retainers, upgraded springs, and head studs. We also sell valve shim kits which are perfect for DIY E30 M3 S14 and E46 M3 S54 valve adjustments.
