Every 60-80,000 miles, we recommend replacing your spark plugs to ensure your ignition system is running optimally. Over time carbon can build up around the head of the spark plug and decrease spark strength and effectiveness, leading to weaker fuel mixture detonation, misfires, and potential check engine lights. To prevent this, have put together our High-Performance Ignition Service Kits. These kits include new Bav Auto High-Performance Ignition Coils, new spark plugs, dielectric grease, and a BMW spark plug service label to keep track of when your spark plugs were replaced.
Bav Auto's Ignition coils feature core windings that have been modified to increase firepower and promote a faster, more efficient burn. This gives your BMW/MINI increased torque in the lower range of RPM and more horsepower in the upper range. Exact improvements depend on the current condition of your engine, but you'll definitely feel the difference. They'll also improve your fuel economy.
From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.
As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

Often an oversight in maintenance, ignition components are also susceptible to wear and tear. Spark Plugs can accumulate carbon, reducing the spark intensity and it's ability to properly ignite the air/fuel mixture, leading to misfires and generally declining performance. Other ignition components, such as coils, boots, wires, caps, and rotors, can also wear out over time due to factors like heat and contamination, preventing the current from reaching the spark plug.
To start over fresh with all new components, we now offer these Ignition Service Kits. Each kit comes with brand new OE quality components, replacing any potential fault points in your ignition system for peak performance!

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.
Bosch is one of the largest OEM producers of Genuine BMW and aftermarket parts in the world, providing parts for almost every major automotive manufacturer. Bosch has likely supplied many of the original electrical (and mechanical) parts for your BMW. Thanks to their quality, high durability, and reliability, you should expect a long service life from Bosch products.

By the early 1990s, BMW had phased out its canister-style ignition coil in favor of an individual coil-on-plug system. The venerable M50 was one of the first engines to receive this update, which boasts greater overall efficiency through increased ignition control and spark energy. Unfortunately, over two decades later, the ignition coils used on the M50, M52, S50, and S52 engines are antiquated at best. Our team of engineers and BMW enthusiasts realized the need for an ignition system upgrade and set out to modernize the M5X ignition system with performance ignition coils pulled from the B58 parts bin.
WHY UPGRADE?
B58 ignition coils provide up to 2.5 times more spark energy than OE M5X ignition coils, effectively eliminating misfires even on high-performance setups. Whether your vehicle is heavily modified or completely stock, these ignition coils deliver unparalleled performance with zero downsides! For tuners, the Turner Motorsport kit also allows for precise adjustments to ignition dwell time through standalone engine management, giving you complete control over your engine’s performance.
Our kit utilizes the factory mounting locations and includes a proprietary boot design with a built-in 1k OHM resistor. Unlike many aftermarket options, our design prevents electrical contact springs from burning out, ensuring long-term reliability and durability. The included ignition coil bracket and cover plate are manufactured from durable 5052 aluminum, combining rugged durability with a premium aesthetic. Designed and optimized in-house using cutting-edge 3D scanning hardware and CAD software, our kit ensures a perfect fit and a clean, factory-like appearance. Installation is a breeze with the included adapter harness, allowing you to add modern ignition coils to your M5X with ease!
Eliminate misfires and unleash the full potential of your M5X-equipped BMW with our industry-leading B58 ignition coil upgrade. Designed for easy installation and unparalleled reliability, it’s the ultimate plug-and-play solution for performance enthusiasts.
FEATURES:
B58 ignition coils offer upwards of 2.5x more spark energy than the OE M5X ignition coils Eliminates common ignition system defects - no more chasing misfires or swapping around coil packs! The included brackets, cover plates, wiring harness adapters, and proprietary boots make for an easy installation Confirmed functionality with factory M3.3.1 (OBDI) and MS41 (OBDII) DME software PART DESIGN:
Bolt-on ignition coil brackets are manufactured from 5052 aluminum and feature a black anodized coating for superior durability, ensuring a lasting finish 5052 brushed aluminum cover plates ensure a cohesive, OEM+ aesthetic Utilizes factory ignition coil mounting locations and corresponding hardware for easy installation Our proprietary rubber boot design incorporates the factory B58 1K OHM resistor, preventing the electrical contact failure commonly associated with other aftermarket kits Coil adapter harnesses feature durable Weatherpack connectors, safeguarding each wire from exposure to water Compact design allows for retaining the factory beauty cover and/or clearance with aftermarket top-mount turbocharger kits KIT CONTENTS:
