BMW Engine Parts for BMW 3 Series E93 (2007-2013)

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 current replacement for some BMW 6 and 8-cylinder engines built in the late 2000s and after. 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. It's listed as a replacement coil for N20, N55, and S55 engines. In March 2015 BMW approved it for N51/N52 engines. This part number replaces the previous BMW part number 12137594937 for the cars listed below.

Sold per coil. Includes boot and connector.

Upgrade your stock oil cooler thermostat for improved performance. Swap your factory 110-degree Celsius thermostat for a new 70-degree Celsius version for faster oil flow and extended temperature control. With oil temperatures reaching 230 degrees Fahrenheit by the time your factory thermostat opens, initiating oil flow at lower temperatures proves more effective than attempting to cool down already elevated temperatures.

Utilizing a factory-style thermostat, this upgrade can be used in all weather conditions and allows your engine to warm up properly, unlike thermostat bypass kits.

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.

The factory magnesium valve covers on the S65 engine are known for developing micro-porosity, corrosion, and persistent oil leaks over time. This material is highly susceptible to oxidation, leading to unsightly surface imperfections, weakened gasket channels, and sealing issues that a simple gasket replacement won't fix.

Upgrade to this high-strength aluminum valve cover set, engineered as a direct-fit replacement for your aging OEM covers. Unlike magnesium, aircraft-grade aluminum offers superior durability, enhanced heat resistance, and complete immunity to the corrosion issues that plague factory covers. Whether you're refreshing a high-mileage M3 or seeking long-term reliability, this upgrade ensures a leak-free, worry-free solution for your S65.

This valve cover set includes gaskets, bolts, and oil separators for a comprehensive replacement.

Features:

Eliminates the common porosity and corrosion issues found in factory magnesium covers.

Helps maintain optimal engine temperatures and enhances long-term reliability.

Gloss red finish provides a much-needed boost in engine bay aesthetic.

Designed for an OEM-like installation without modifications.

Reduces the risk of oil leaks, ensuring a proper seal.

Resistant to oxidation and chemical exposure for a long-lasting clean look.

This is an OEM INA Idler Pulley, also known as the roller pulley or deflection pulley. The idler pulley is known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).

OEM Schaeffler (INA, LuK, & FAG) is an engineering company that focuses on high-performance, precision manufacturing. With their individual brands INA, Luk, and FAG providing exceptionally high quality parts directly to BMW, as well as countless other automotive companies, their history of reliability and variety of offered parts makes Schaeffler a go-to replacement parts provider for all of us here at Turner Motorsport.

The valve cover gasket seals the valve cover to the cylinder head, preventing oil leaks and maintaining engine integrity. Over time, exposure to high engine temperatures causes the gasket's rubber construction to degrade, leading to significant oil leaks. This often presents as a noticeable "burning oil" smell at idle, caused by oil dripping from the valve cover onto the hot exhaust manifolds.

If your valve cover gasket is failing, restore proper sealing and prevent further leaks with this premium OE replacement from Bremmen Parts.

Note: This gasket is designed for the left-side cylinder bank (cylinders 1-4). For the right-side cylinder bank (cylinders 5-8), see T#36913369.
