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.

This Bremi coil was used in M42, M50, M50tu, and M60 engines.

MINI B38/B36 JMTC Refurbished Turbocharger offers a complete overhaul to restore turbocharger performance to a like-new condition. JMTC's refurbishment process includes a thorough cleaning and replacement of all internal components that may have been worn or damaged, such as turbine shaft bearings, thrust bearings, pressure seals, cartridges, and end housings. Components not meeting stringent standards are replaced, ensuring optimal performance.

• Thorough Overhaul: Includes cleaning and replacement of all internal components to ensure reliable functionality.
• High-Quality Parts: Only components meeting strict quality standards are used, with damaged parts replaced.
• Extended Warranty: Refurbished units retain JMTC's full warranty for added peace of mind.

Additional Recommendations:

• Pre-Installation Tips: For optimal results, JMTC recommends refurbishing the OEM catalytic converter or using a high-flow downpipe and installing a new oil line. This helps prevent recurrence of previous issues and ensures the turbo operates at its best.

JM Turbo Cooper - Extreme GTD47 K04 Turbocharger Upgrade

JM Turbo Cooper offers the Extreme GTD47 K04 turbocharger upgrade designed to deliver outstanding reliability and high-performance gains for the 2007+ MINI Cooper. This upgrade is a top choice for Mini and Peugeot owners, providing exceptional power output for applications exceeding 280hp.

Update: The improved gasket design on the back side now features a seamless gasket inset, and the package includes a new gasket for your convenience.

The JMTC Extreme GTD47 upgrade boasts a high-pressure, high-flow, dual-scrolling turbo that features a substantial 50mm compressor wheel. This design ensures maximum boost at the top end of the RPM range, making it ideal for track, off-road, and extreme street applications. The large GTX exhaust turbine complements the setup, delivering extra boost at high RPMs and preventing torque loss compared to the stock K03 turbine.

Whether you seek extreme track performance, drag strip dominance, or unrivaled street upgrades, this turbocharger is the perfect choice. It offers impressive torque and durability, outperforming many other options on the market. To fully unleash its potential, we recommend pairing it with one of our aftermarket exhaust systems.

It's important to note that to harness the additional power, a custom tune is required. Running without a tune will result in minimal to no HP gain.

Estimated Power Gains:

• Approximately 60hp with a tune, intercooler, downpipe, cold air intake, new plugs, basic maintenance, and carbon blasting/cleaning.
• 120hp or more with all the above modifications, plus a ported head, larger valves, ICE pipe, intercooler, and a 3"+ or larger exhaust system.

Extreme GTD Upgrade Features:

• Brand new turbo!
• 47mm billet compressor
• High-flow GTX exhaust turbine
• High-strength K04 internals
• Upgraded 360-degree bearing
• Designed for higher pressure
• High-temperature alloy turbine housing
• Dual-scrolling turbine housing
• Water-cooled bearing housing

For engine and turbocharger reliability, JMTC recommends a 3.0" or larger downpipe/exhaust size for the GTD turbochargers. Please avoid using the stock downpipe or stock-sized catalytic converter.

The OEM intake boot can be used with the removal of the inner sleeve for N14 engines. For N18 engines, the OEM boot at the turbo connection will need to be heated and expanded slightly, which can be done with a heat gun. This turbocharger also fits AEM intake, NM Eng intake, and Forge Intake (Boot). Please note that the hose might need to be warmed and stretched over with a hose expander.
