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!

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.

Underdrive Power Pulleys work to 'free up' horsepower. Any accessory that spins from the main drive belt is using up power. That's power that could otherwise be used to move the car. By giving some of that power back to the engine, you can make the car faster! It's like FREE HORSEPOWER! We measured 10.7 whp at 6960 rpm and 8.1 lb-ft of torque at 5550 on a 1995 M3.

Underdrive pulleys for your BMW will slow down engine-mounted accessories - the water pump, power steering pump, and alternator*. These systems contribute to 'parasitic losses' - power lost from what the engine could produce if it did not have these systems. Since less energy is used to move them, that power is transferred back to the engine and used to propel the car. Our pulleys give a 10-20% reduction in rotation, releasing up to 11hp on most BMW six-cylinder engines. There's also a small but noticeable improvement in throttle response too! We have done extensive testing and development work, both on and off the track, to ensure that the accessory systems function as they should. On our Racing pulley kits we actually underdrive certain components more so we feel our Street pulleys are an ideal compromise between power/torque gains, reliability, and system performance. Our pulley kits have been on the market for over ten years, and used in all of our own cars, with zero component failures related to their use.

Our pulleys are made from T-6061 aluminum and finished in a durable black hard anodize that is very resistant to wear, chemical exposure, and heat. We designed our pulleys to look similar to the factory parts but also to be stronger and, in most cases, slightly lighter too. For example, a Turner alternator pulley is less than half the weight of the stock steel pulley! With our hardcoat aluminum you will never have to worry about a serious failure of a stock plastic pulley. A 'stealth' approach to aesthetics was our goal and we let the results speak for the pulley design. Installation is straight forward and easy with simple hand tools. Removal of the fan is required for access to the front of the engine. Total install time for a 3-piece pulley set should be around 1.5 hours. A new longer belt is included and we also recommend replacing the separate A/C belt, belt tensioners, and the guide and deflection pulleys at the same time.

Alternator Pulley Options
(click to expand)
Bosch or Valeo? BMW built your car with either a Bosch or Valeo brand alternator. Unfortunately, the pulley is not the same for both brands. The brand is usually printed on the black plastic cover of the alternator but may be facing the frame rail or the ground. If you know which brand you have, select your option below and we'll send you the correct alternator pulley for your BMW. Don't know which you have? NO PROBLEM! We can send you both. The 2nd pulley costs $40 but you will receive a refund once we get the un-used pulley back (return shipping not included).
Aftermarket Stereo Systems
(click to expand)
We offer our kits in two different ways: the full Power Pulley Kit with all 3 pulleys or a 2 pulley kit if you do not wish to underdrive your alternator (for large stereo systems or other battery-draining modifications). Our kits have been tested for compatability with the factory premium stereo systems (Harmon Kardon, etc). But any major alterations or upgrades from the factory system will work best with our 2 pulley kit and no underdriving of the alternator. For all stock stereo systems the 3 pulley set is recommended because the Turner alternator pulley will help make more power and is also much lighter than the stock pulley.

WPC Treated Genuine BMW Rod Bearings Set - S54
Turner Motorsport - Corporate Logo
T#:556240
Part#: 11247835439KT01
In Stock
$573.95
Free Shipping on orders $49 and up

These WPC-treated bearings are the best we have seen for the S54. WPC is a shot-peening treatment at a microscopic level. It's perfect for sensitive surfaces like bearings. The WPC treatment removes imperfections and high spots, while creating a surface that retains oil better than the original surface. This greatly reduces friction. The bearings in this kit are factory BMW bearings that are sent to WPC for treatment. The treated bearings are stronger with less metal fatigue and less friction than buying off-the-shelf bearings from the dealer.

Price is for a complete set of S54 upgraded rod bearings.
