Free additional power to your M3’s rear wheels without sacrificing or compromising your BMW’s reliability. Machined from 6061-T6 aerospace aluminum, Macht Schnell Performance Underdrive Pulleys are strong as well as lightweight to limit parasitic drag from the accessories within a moderate level for maximum performance on or off the track. After machining and engraving, pulleys are then T3 hard anodized for additional strength, anti-corrosion & wear resistance. Our DualDrive design replaces the Crank Accessory & Power Steering Pulleys, resulting in an additional 9-14 HP and 7-9ft. lbs TQ gain for the M3. Gains are due to a reduction in power required to turn accessories; an increase in accessories lifespan due to lower speed will also result. All factory harmonics/balancing are undisturbed. Macht Schnell Performance Underdrive Pulleys have no negative effect on accessory operation and comes fully equipped with new belts. Already have this kit and need new belts? See T#14491 and T#14489 Performance Underdrive Pulleys Features: DualDrive design allows maximum performance, with minor effect on accessory speed Proper cooling temperatures are retained at proper levels on or off the track Maintains proper alternator speed, allowing sustained levels to sensitive control modules Machined from 6061-T6 aerospace aluminum T3 Hard-Anodized for maximum strength and corrosion/wear resistance No affects to crankshaft dampening or harmonics Simple bolt-on installation

The N54 engine is no stranger to oil cooling problems, that’s why we recommend installing the MSL Oil Thermostat. The standard oil thermostat will reach around 120 degrees Celsius with a normal driving style. The MSL Oil Thermostat will open at a lower temperature than the standard oil thermostat (at 85 degrees Celsius) and will keep the temperature stable between 95 and 105 degrees Celsius. Installing the MSL thermostat ensures a cooler oil temperature which will result in more stable performance, but above all this improves the reliability of the engine. It is recommended to install the thermostat, especially for cars that are tuned.

MSD Performance Coil Pack for MINI

Before ordering, check whether you need round or flat pin connectors for your MINI's coil pack. The type of pin is determined by the connectors that link the coil to the wiring harness. To check, slide the red locking tab to the right, press down on the tab, and pull the connector off the coil. Examine the pins to see if they are flat or round. Reattach the connector by pushing it back on until it clicks, then slide the red locking tab back to the locked position.

This high-performance coil pack is a popular upgrade among MINI owners looking to enhance their vehicle's performance over the stock coil. The installation requires removing the factory bolts from the old coil and modifying the MSD factory sleeves by drilling out 1/16" to fit the stock bolts.

Kits Include:

MSD Coil Pack
MSD Wire Set - Red
Inductance: 7mH
Maximum Voltage: 36,000 Volts
Primary Resistance: 0.51 OHMs
Secondary Resistance: 12K OHMs
Turns Ratio: 77:1

Key Benefits:

Upgraded performance over stock coil pack
Enhances ignition efficiency and engine performance
High voltage output of 36,000 volts for stronger sparks
Low primary resistance of 0.51 OHMs for efficient energy transfer
High secondary resistance of 12K OHMs for improved performance
Durable construction for long-lasting use
