Transmission fluid is responsible for both cooling and lubricating sensitive transmission components. Over time, this fluid becomes contaminated by particulate from clutch and gear components wearing down. This contamination reduces the fluid's ability to act as a lubricant, eventually leading to increased wear and tear within the transmission. To prevent excess wear and keep your transmission in top shape, the fluid and filter should be replaced regularly. As per ZF's recommendations, we suggest performing a full service on your 8HP automatic transmission every 50,000 miles. If your vehicle has been modified to produce more power than stock or if it is regularly track-driven, we recommend shorter 30,000-mile service intervals. This will ensure your transmission's fluid is free from contamination, which will help extend the life of internal transmission components, such as clutch packs and solenoids.

Plastic thermostat housing cracked on your M50?

Here are your choices: you can wait for the plastic factory thermostat housing cover to break and cause major overheating. (Even with a new stock cover, it won’t take long.) Or you can install a thoughtfully engineered all-aluminum thermostat housing cover from Active Autowerke and never experience this type of failure again. Currently there is no factory upgraded part to this problem. This is an aluminum extruded part that has all of the openings machine properly to fit like factory; from the mounting bolt holes, the seating of the thermostat to the sealing opening for the ORANGE gasket. Forged to exact factory tolerances, everything fits and this unit is a true easy bolt-on – especially suited for racing or load conditions like heavy traffic, where engine temp can rise rapidly. The housing is guaranteed never to break from overheating or over-tightening, and its CNC machined surface ensures a precise seat.

Unit comes complete with a new ORANGE sealing gasket; a new thermostat is recommended but not included.
For hotter climates, a 71 degree thermostat is recommended over the 82 degree unit.

Anything and everything BMW is the mantra at Active Autowerke. Since 1981 they have been serving the BMW community with custom turbocharger kits to a myriad of other innovative and inspiring performance parts.

For Alternator / Water Pump Belt

Hydraulic Belt Tensioner for E36, E46, E39 6-cyl models. This is the oil-filled tensioner that keeps the main drive belt in the proper tension. Over time the piston seals inside allow fluid to leak out. The tensioner becomes frozen or inoperable. Replacement is the best corrective action to take. This can be done during any belt or pulley service or anytime the fan is off the engine.

This weighted shift knob makes shifts faster and the extra-large globe shape encourages over-palm shifting. The Black Forest Industries Billet Knob weighs in at 8.8oz (250g), about twice as much as a stock knob and a little heaver than the BMW ZHP knob. The heavier knob amplifies the pendulum motion of the shift lever resulting in smoother and faster shift times. BFI has designed this knob for BMW and VW fitments to fit snug on the shift lever and be secured with Allen set screws. They were careful to reduce tolerances compared to universal knobs. The overall height of the BFI knob is the same as stock anatomic knobs (some BMW M/Performance models have a stock knob that is shorter than this one).

Included with the BFI Billet knob is a matching BFI crest shift emblem. A 5 or 6-speed pattern emblem is available separately.

Choose from soft alcantara or perforated air leather with either a silver or black anodized base.

This is an OEM INA tensioner pulley, also known as the adjusting pulley and lower pulley. This pulley is mounted on the belt tensioner near the center of the belt assembly. The upper and lower pulleys are known to be the primary sources for 'belt squealing'. This pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).

This pulley is mounted along with the hydraulic belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-M54 family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines). This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time. If you have a mechanical belt tensioner, the pulley can only be replaced with a new tensioner.

OEM Schaeffler (INA, LuK, & FAG) is an engineering company that focuses on high-performance, precision manufacturing. With their individual brands INA, Luk, and FAG providing exceptionally high quality parts directly to BMW, as well as countless other automotive companies, their history of reliability and variety of offered parts makes Schaeffler a go-to replacement parts provider for all of us here at Turner Motorsport.

As a leading source of high performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts.  All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

This is an OEM INA Upper Idler Pulley, also known as the roller pulley or deflection pulley. The upper and lower idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).

These lifter buckets can last 150,000+ miles but then they no longer fit on the valve stem correctly and a ticking or knocking noise can result.

1995-1998 E36 BMW 323is 323ic 328i 328is 328ic M3
