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.

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 properlymeasure 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? Turnerrecovered 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
What can you do to get rid of this heat soak? Turner designed an IAT relocation kit that moves the intake air temp sensor to a cooler location. 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 Motorsport Oil Temperature Sensor Flange was designed to get your oil temperature from the best possible location: the sump. Most of the factory and aftermarket sensors are located after the oil pump, which does not give you an accurate temp reading of the oil that is actually lubricating the engine. At the factory temp sensor location the sensor picks up heat not only from the oil stream, but also from the oil pump and housing which will skew the reading. Other aftermarket adapters can be give inaccurate readings from their location and/or design limitations. And may require making unnecessary modifications. By relocating the sensor to the oil sump it reduces clutter and sits flush against the bottom of the oil pan to avoid potential clearance issues. Testing that we have done on and off the track shows that the sump location is the most accurate. We accomplish this by removing the factory oil level sensor or block off plate and using the existing hole and bolt pattern on the oil pan with no additional modifications. Any sensor with an M12 x 1.50mm thread can be used in the flange.
Note that removing the factory oil level sensor will trigger the low oil fault/warning light. There's no elegant way around this but since the Temp Flange is considered a race-only part we assume you will be checking your own oil level anyway or be using a stand-alone dash/engine management system that does not track oil level. And having the most accurate oil temp is more important.

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!
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.

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).
Stereo Systems. We offer our kits in two different ways: the full Power Pulley Kit with all 3 pulleys or as a 2 pulley kit if you do not wish to underdrive your alternator (for large stereo systems or other critical-charging modifications). Our kits have been tested for compatability with the factory premium stereo systems (Harmon Kardon, etc). But any major upgrades from the factory premium systems will work best with our 2 pulley kit and no underdriving of the alternator. For all stock stereo systems the full 3-piece set is recommended because the Turner alternator pulley will help make more power and is also much lighter than the stock pulley.

Through experimentation and data acquired from our E36 World Challenge Touring Cars, it was discovered that in long corners and under heavy braking that there was an oil starvation problem in the M50 and M52 engines. This system was developed to keep oil in the sump and eliminate the starvation problem. After several iterations, further testing and data acquisition in the Touring Cars showed that this system eliminates the problem of oil starvation. This is a less expensive alternative to replacing the stock oil pan with the factory BMW M3 Lightweight oil pan, while still achieving the similar results.

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors).

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code but not always a check engine light. A misfire code may be related to an ignition coil but could be from other things as well. Sometimes a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.
