If you've ever bled the clutch hydraulic system on your BMW, you know how frustrating it can be. Designed with both DIY enthusiasts and professional technicians in mind, our clever tool simplifies one of the most notoriously annoying steps in clutch service.

Crafted from high-quality aluminum and finished in a durable black anodized coating, our clutch slave cylinder bleeder tool is built to last. Its function is simple: the adjustable piston rod applies controlled pressure directly to the clutch slave cylinder’s piston, compressing it and reducing its internal volume. By minimizing the amount of air trapped inside the cylinder, bleeding becomes faster, cleaner, and far more effective—no more endless pedal pumping or inconsistent clutch feel. The result is firm, consistent clutch pedal engagement and a smoother overall driving experience, all achieved with less time and effort underneath the car.

Hub Extenders are the solution that no one else has! BMW wheels must fit on a hubcentric lip to be securely (and safely) mounted to the hub. But with a 3, 5, 8, or some 10mm spacers on a lip measuring no more than 11mm that presented a huge problem - there would be no lip left over for the wheel to rest on! As one of the world's leading BMW tuners and race teams, we came up with a way to extend the lip and get back the lost surface area for the wheel to safely mount on. Our Hub Extenders are the first of their kind.

Hub Extenders fit where the stock dust cap is usually fitted on the front wheel hub. Pop out the dust cap and tap the Hub Extender into its place. It becomes an extension of the original lip. These will only work on the front hubs of the cars listed below because the rear hub is tapered inside (narrows down). These will not work with Xi AWD models because the front axle shaft protrudes through the hub. With Hub Extenders in place you can use nearly any flat wheel spacer - 3mm, 5mm, 7.5mm, 10mm, or possibly more without worrying that the wheel will not be securely seated. This is perfect for wheels that have chamfers on the back of the wheel that don't match up to existing spacers (Kosei K1 spacers for example).

Turner Hub Extender Features --

+ hub extension makes flat spacers a true hubcentric fitment
+ precise tolerance fitment thanks to CAD process and CNC mill machine
+ aerospace grade aluminum  light weight but very strong with a high resistance to corrosion
+ additional military-spec hardcoat for further corrosion resistance
+ stealthy black color with laser engrave Turner logo
+ Turner Motorsport track and street tested!
+ Made in the USA

Wheel Limitations. Special consideration needs to be taken since wheel design and manufacture differ from brand to brand. The key dimension is the dept of the center bore. Some wheels won't work with larger spacers and a Hub Extender because of the additional protrusion into the center bore. Please measure your wheel to make sure it can accommodate an extra 2.5-5mm of hub extending into the center bore. Click here for a diagram.

Hub Limitations. BMW has multiple hub designs but not all are compatible with our Hub Extenders. The inside lip of the hub must be flat and smooth for at least 13mm (the depth our Extender fits into the hub). Some BMW hubs have a bowl shape or have tapered inside walls which will prevent the Hub Extender from seating all the way. Remove the hub dust cap to check before opening your Turner Hub Extenders.

Flexible silicone smooths the intake tract while allowing for a range of performance intakes fitments. The ultimate in durability!

In most vehicle applications, the rubber intake elbow found in the intake system is not designed for performance or modification. They were designed to get the job done but when you add a performance filter, intake or tune, the stock elbow will start to show it weakness. The stock rubber elbows disrupt air flow as it passes over the accordion sections causing unwanted turbulence and negating the effects of intake modifications.

With high quality 4 ply construction, the Turner intake boot is strong but flexible, ensuring a secure fit on an OEM or aftermarket intake system. A smooth interior ensures unimpeded airflow, while a smooth, unassuming exterior adds to any engine bay.

Benefits:

Improved throttle response,
Increase induction sound
Increased power output - and power output, Best when paired with an ECS drop-in air filter.(ES4461001 or ES4460965)

All vehicles will lose some degree of performance due to heat soak under the right operating conditions.  Engine management systems constantly monitor operating conditions and modifying parameters based on sensor inputs. BMW integrated the intake air temp sensor in the MAF housing on models such as the E39 M5, and, being sandwiched behind a hot radiator and in some applications next to an even hotter valve cover, this is less than ideal for performance applications. Absorbing excess heat from its surroundings, the MAF can’t shed it fast enough, and the ECU reads an inaccurately high intake air temperature. Compensating for this false hot air measurement, the ECU pulls timing and runs a richer fuel mixture, resulting in a significant loss of torque.

What can you do?  Locate an intake air temp sensor in a location where it can properly measure incoming air temps and where it's less prone to heat soak. Mounting the sensor further away from the heat source and isolating it from the MAF housing, it can both resist the effects of heat soak longer and respond to temperature changes more quickly.  The result is you’ll experience reduced torque loss and more consistent power output when you’re pushing your engine hard. 

The Turner engineering team was initially skeptical of the claimed performance benefits of this modification. They first set out validate the functionality and performance benefit of a temp sensor relocation. Replicating stop-and-go traffic heat soak in a 2001 540i was a simple task in a controlled environment - their dynometer. First the car was heat soaked to simulate being stuck in traffic or moving at low speeds by running the car four times on the dyno with the dyno's cooling fans disabled. The fans were then turned on for three more runs to observe the recovery rate once air flow was reintroduced. The test: following this procedure once with a stock IAT, and once with their relocation kit in place. 

The result? Turner recovered 11lb-ft torque at 2500rpm through use of their relocation kit, with even greater recovery to be found for M5 owners. Here are the heat soak-related torque losses Turner experienced:

Stock IAT location:
18rwtq at 2500rpm
10rwtq at 3000rpm
9rwtq at 3700rpm

Turner IAT Relocation:
7rwtq at 2500rpm
5rwtq at 3000rpm
5rwtq at 3700rpm

The Turner engineering team designed a complete plug and play kit (unlike all other options on the market) that makes for quick, easy, and reversible installation. Weather-sealed connectors keep out the elements, while sheathed wiring offers a clean appearance underhood. With a harness nearly 3 feet long - the Turner IAT relocation kit offers flexibility in positioning, but not too long that you're left with unsightly excess wiring. Turner recommends positioning the sensor in a location away from engine heat, but still within the intake ducting to achieve accurate intake temp readings - such as the far side of the base of the airbox. Vehicles with cold air intakes with cone-style filters can even position the sensor in the end of the filter. Simply drill a hole in your (cool) location of choice and plug in the harness. More information including installation instructions and some good examples of sensor mounting locations can be found in our DIY PDF. 

We include everything you need to relocate your IAT, just select your desired sensor brand below - Genuine BMW or original equipment Beru.

Also the perfect plug-n-play option for anyone looking to upgrade their intake to utilize an Alpha-N tune!

Note for vehicles with M62 engine: applicable to 1999 and up

Unlock the full potential of your S54’s valvetrain with our High Performance Cam Followers/Rocker Arms, built for precision, durability, and reliability in high-revving performance engines.

Crafted from forged chromoly steel and finished with a diamond-like carbon coating, these cam followers are engineered to deliver exceptional strength, reduced friction, and outstanding wear resistance, ideal for demanding street or track use. Each unit is precision-ground for consistent clearances and smooth, stable valvetrain motion at all RPMs. Despite heavy-duty construction, our design retains the same weight as the factory rocker arm, preserving OE valvetrain geometry and balance while offering superior longevity and performance.

Rocker arms wear in conjunction with the camshafts, meaning the two must be replaced simultaneously. Aftermarket and performance camshaft options (Schrick, CAT-Cams, etc.) are typically ground from softer blanks and, as a result, cannot be used with factory rocker arms. We tested our performance cam followers with aftermarket camshafts to validate compatibility, ensuring smooth, reliable, and safe operation under demanding conditions.

Features:

Forged chromoly construction for maximum strength and durability Diamond-like carbon-coated surface reduces friction, extends service life, and permits compatibility with aftermarket and performance camshaft options Precision-ground tolerances ensure consistent and quiet operation OEM weight match maintains valvetrain balance and reliability Superior wear resistance for performance and endurance applications NOTE: Rocker arms are wear items and must be replaced alongside a new set of camshafts, regardless of profile or manufacturer. Installing a new set of rocker arms onto a used set of camshafts is NOT recommended.

Kit Contents:

One set of 12 DLC-Coated Rocker Arms (services intake OR exhaust camshaft) 24 Rocker Arms / 2 Sets of 12 Rocker Arms required to complete both intake and exhaust camshafts. Product Development: Our Turner Performance Rocker Arms are the result of advanced engineering, testing, and quality assurance by Turner’s Research & Development team. Every stage of development employs FARO laser scanning, SolidWorks 3D CAD modeling, and in-house rapid prototyping for precise fitment and design validation. Performance and durability are proven through Mustang AWD 500 SE dyno testing and Superflow SF-750 Flowbench analysis, ensuring each component meets Turner’s uncompromising standards for performance and quality.
