Ignition Service for BMW 3 Series E91 (2006-2012)

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!

See kit contents below for a complete list of included components.

For BMW M54 applications, coil styles vary between M or N depending on the vehicle's production date. Models produced up to September 2002 require the M series style coil, while those manufactured after September 2002 use N series style coils. It's crucial to visually compare and verify the correct coil needed for your vehicle before making a purchase.

Benefits:

• Specific coil styles for different BMW M54 application dates
• Helps ensure the right replacement part for your vehicle's coil
• Visual verification recommended prior to purchase for compatibility

Revitalize your BMW's performance by addressing poor idle, fuel inefficiency, and engine misfire issues caused by worn-out spark plugs. NGK offers the ultimate solution with their high-quality aftermarket spark plugs. Over time, electrode wear leads to increased gaps and weakened sparks, while carbon buildup can impair performance. These upgraded plugs are designed to restore power, fuel efficiency, and smooth out an irregular idle, ensuring optimal engine functionality.

• Solves poor idle, low fuel efficiency, and engine misfire problems
• Enhances engine power and fuel efficiency
• Addresses electrode wear and carbon buildup issues
• Ensures quality NGK replacement for improved 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.

This is the OEM Bosch ignition coil for the N52 engine used in cars up to 4/2006 production date. You can find your car's production date on the driver's door pillar in MM/YY format. BMW has made numerous changes to ignition coil part numbers in recent years but has approved this part number to work in the vehicles listed below. This part number replaces previous BMW part number 12137548553.
