This is a must-have for ALL BMWs, and simply installs in place of your existing drain plug. With every oil change you perform on your BMW, you'll be able to inspect for metal shavings and debris. Many times, if something is going wrong on your BMW's engine, the magnetic drain plug can give you an early warning. Our championship race team uses this info all the time (Ever find a piece of a valve spring in your oil? We have!) Be sure to get one now, and make the swap next oil change!

When we designed this catch we wanted to have the most function options available, the best separation method, and the easiest to service. The Turner engineered catch cans offer a pre-setup design based ion desired flow direction, however, this does not limit you to this flow. The inner baffle orientation can be easily adjusted to flow in both directions in case you decide to move this catch can to a different vehicle. A 4 chamber system baffle system inside the catch can was engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can. Having a closed/recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation.

Turner E9x Cowl Delete Harness Mounting Bracket mounts to factory bolt holes; it is an easy no-drill install that creates a solid location to tie back your engine harness. However, removing the cowl introduces the possibility of dirt and debris entering your cabin. To solve this issue we suggest pairing it with Burger's Cabin/Cowl Delete Filters. These are small, dry, and maintenance-free filters that both add a finished look to your engine bay and prevent debris from entering the cabin.

Upgrade your engine build with Turner's WPC-treated Race Series Bearings, engineered for serious performance enthusiasts. Starting with ACL’s high-performance bearing shells, these Race Series bearings are built to withstand extreme RPMs and stress. Utilizing a "Duraglide" tri-metal construction and a high-strength overlay plate, these bearings offer superior oiling and heat resistance for high-RPM operation.

Our WPC-treated bearings take ACL’s already impressive design and enhance it even further.

This advanced surface treatment ensures smoother operation and improved heat dissipation, which are critical for any high-performance engine.

Key Features:

Duraglide Tri-Metal Construction: ACL's Race Series bearings feature a high-strength overlay for enhanced performance. Optimized Oiling: Designed to promote better oil flow during high-RPM conditions. Precise Fitment: Manufactured with OEM-level precision using micron tolerance machining. WPC-Treated for Strength: Surface treatment adds strength and reduces friction for improved engine performance. No Flash Plating: Allows for better heat transfer and bearing retention. Thermal Discharge Process: Smoother, stronger components through WPC’s unique thermal discharge technology. Enhanced Heat and Friction Resistance: Built to combat the biggest enemies of high-performance engines. Don’t settle for standard bearings—choose Turner Motorsport WPC-treated Race Series Bearings for the ultimate engine performance upgrade. Perfect for your next engine rebuild or rod bearing service!

We know if a soft mount offers a sloppy connection it doesn't work on the track, and a solid mount isn't acceptable as a daily driver (for most!) and set out to engineer a mount that would meet the needs for both. At the core of our enclosed design is a partially-constrained, multi-piece polyurethane bushing with precisely-set preload. This architecture absorbs and disperses resonant engine frequencies as opposed to amplifying them (like some other designs do), which results in a positive-connection, enthusiast-feel mount with the vibration.

The inner baffle orientation can be easily adjusted to flow in both directions in case you decide to move this catch can to a different vehicle.

The idea of power pulleys is simple. The less effort the engine puts into running accessories such as the water pump, power steering, pump alternator etc., the more of that power can be used elsewhere - your wheels! The way this is done by reducing the rotation of the pulleys by as much as 10-20%! The end result is more horsepower at your disposal. Turner has done extensive testing (on and off the track), to ensure that the accessory systems still function as intended and without failure. These pulleys offer an excellent compromise of power gains, reliability, and performance.

The oxygen sensor is vital to the performance and drivability of your car. The engine computer relies on data from the sensor to make adjustments in engine efficiency and performance. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance.

This is a Bosch O2 sensor - also known as a Lambda probe. Bosch is an OEM supplier to BMW.

Position: after the catalytic converter (post-cat).

This item fits the following BMWs:
2008-2013 E90 E92 E93 BMW M3 Sedan, Coupe, Convertible

Having your oil pressure light come on can mean very serious problems. Or it could just be this switch that fails several times over a car's lifespan. By no means should you ignore the warning light but replacing this sensor could be the actual culprit. The other problem with this switch is that oil can leak past its seal. With the oil under a lot of pressure at this point, the oil loss can be a serious concern. It's a simple replacement when doing most oil change work.

This Oil Pressure Switch fits the following BMWs:

Free Up Real S65 Power — Engineered the Turner Way Your S65 is already making the power. This kit simply lets you keep more of it. The Active Autowerke Power Pulley Kit for the BMW E9X M3 reduces parasitic drag at the crankshaft, trimming rotational mass and freeing up horsepower that would otherwise be consumed by accessory drive load. The result is a measurable increase in rear-wheel output without sacrificing the balance, cooling capacity, or long-term durability expected from a properly engineered BMW upgrade. The crank pulley is CNC-machined from billet 6061 aluminum and finished with a hard-coat anodize for durability under sustained high-RPM operation. Unlike undersized pulleys that compromise system function, this design maintains proper operating characteristics while delivering real-world gains. Late-2007 production E9X M3 models transitioned to a double-sided (DPK) A/C belt configuration. Rather than forcing a workaround, Active Autowerke developed a proper DPK-compatible solution — including the correct matched belt. Applicable kits also include a spare DPK belt for added insurance. Dyno testing on a Mustang chassis dyno confirms gains of 10–12+ rear-wheel horsepower on an otherwise stock vehicle. Installation is fully reversible and requires no permanent modification. Product Highlights 10–12+ RWHP gain verified on stock S65 engines Complete bolt-on system CNC-machined 6061 billet aluminum crank pulley Hard-coat anodized finish for durability Includes correct replacement drive and A/C belts Spare DPK belt included where applicable Compatible with manual and DCT-equipped E9X M3 Reduces parasitic drag and rotational mass Designed to maintain proper operating temperatures Works in conjunction with Active Autowerke performance software Available for single-sided and double-sided (DPK) belt configurations Fitment Information Confirm whether your E9X M3 is equipped with a single-sided or double-sided (DPK) A/C belt prior to ordering to ensure correct application. A properly engineered solution for enthusiasts who want measurable gains while preserving OEM-level refinement and reliability.
