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

Get MORE HORSEPOWER and TORQUE on your 2006 and newer M5 sedan or M6 coupe/convertible by replacing the stock crank pulley with this specially designed performance version. The Power Pulley reduces rotational mass and safely under drives your belt driven auxiliaries for reduced parasitic power loss. The end result: More power to your M5 or M6's rear wheels! Designed to give the best performance benefit with no sacrifices or compromises to your BMW's reliability. These have been tested on hundreds of cars before public release and there are simply NO DOWNSIDES to this upgrade.
Limited time introductory offer: FREE GROUND shipping on all orders shipped within the 48 contiguous states shipping on this V10 pulley kit.
CNC machined using aircraft grade 6061 aluminum billet, and anodized with a stealthy black coating. Others may advertise "their" crank pulley boasting higher numbers (using a smaller pulley profile), but we have concluded that for street and track driven M5 and M6, this is the best size and design to ensure proper engine temp and auxiliary functionality. As the S85 V10 engine doesn't use a traditional harmonic balancer, all factory harmonics and dampening are fully and properly retained. We've found this pulley alone adds 18 to 22 HP and 17 to 21 Ft/lbs Torque on a stock M5 or M6 with no other mods(!!).
The E60 M5 / E63 M6 Power Pulley Kit includes:
(1) Underdrive Crank Pulley
(1) Correctly Sized Drive Belt
(6) Allen Head Bolts
(1) Installation instructions
This underdrive pulley fits the following BMWs:
2006-2010 E60 M5 sedan
2006-2010 E63/E64 M6 coupe & convertible

Designed and manufactured by Clevite to BE Bearing specifications.
These bearings replace the factory BMW rod bearings. The original BMW bearings have too little clearance, which leads to premature bearing wear and can cause early engine failure. Furthermore, the factory BMW bearings are made from tin-aluminum which are 5-times harder than a softer lead-copper bearing design. A softer bearing is better for your engine and more tolerant of foreign particles suspended in your oil.
These BE Bearings feature a state-of-the-art Clevite Tri-Metal design with the Clevite Tri-Armor(tm) coating.
Fits the following BMWs:
2005-2010 E60 BMW M5
2005-2010 E63/64 BMW M6
Designed by BE Bearings, manufactured by ARP. These custom made rod bolts are designed to be used on BMW factory connecting rods. BE Bearings worked with ARP to come up with custom rod bolt torque specifications to ensure minimal rod big end bore distortion. Their bolts have been measured and verified to guarantee minimal bore distortion, and stay within the ARP torque specification.

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: bank 1, before the catalytic converter (pre-cat).
This item fits the following BMWs:
