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.

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 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.

Rogue Engineering has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This allows for perfect operation in daily driven vehicles without a hiccup or stutter. However, when the demand for power is requested, the power pulley kit allows for the freed power to become apparent. The term "power" pulley is a bit of a misnomer. Underdrive pulleys actually free up power by reducing the drag caused by the accessories. These pulleys are based off a calculated percentage from factory dimensions, so that particular component speeds are safely reduced without affecting their true purpose.

Rogue Engineering has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This allows for perfect operation in daily driven vehicles without a hiccup or stutter. However, when the demand for power is requested, the power pulley kit allows for the freed power to become apparent. The term "power" pulley is a bit of a misnomer. Underdrive pulleys actually free up power by reducing the drag caused by the accessories. These pulleys are based off a calculated percentage from factory dimensions, so that particular component speeds are safely reduced without affecting their true purpose.

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.
