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.

Maintaining proper oil levels in your engine is crucial for peak performance. Undetected leaks can cause your oil to drop to dangerously low levels between oil changes, leading to severe engine damage.

One common culprit for oil leaks is the valve cover. Over time, exposure to extreme temperature fluctuations can wear down the gaskets, causing them to fail. Prevent oil leaks and protect your engine by replacing these vital components.

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.

Proper valve lash adjustment is critical for longevity and performance. If your S54 is due for valve adjustment maintenance you can do it yourself with this kit, saving hundreds of dollars in labor charges. 

Includes

• Shim set 
• Installation tool #83300493743
• 16 Blade Feeler gauge set 

BMW recommends S54 valve inspection and adjustment every 30k miles.

The N54 suffers from a weak point in its crankshaft. It has been reported that when increasing the power to the engine, the crank hub can move or spin slightly under an extreme load. This is most apparent under high-rev downshifts or in the case of increased boost pressure which creates more stress on the engines rotating assembly. In order to keep this from happening, the crank bolt must be secured to the hub to keep it from backing off, but this can be a tricky solution since a simple dab of Loctite will not suffice. 

Here is an easy, and cost-effective way to secure the situation; The VTT N54 crank bolt capture. This lightweight and durable ring slips over the head of the crank bolt fully encapsulating it, and locks it to the crank hub and eliminating its ability to spin. The VTT-CBC is 100% Billet Aircraft Grade Aluminum, Anodized black to protect it from the elements, and give it a stealth look. What's more is that it weighs only 1.3 Oz's meaning you aren't adding excess mass to the crankshaft which will avoid any imbalance or vibration issues.

While this is not a full fix for all crank hub spinning issues, the engineers at Vargas have found most issues have stemmed from the bolt itself backing out, and this is a great way to keep that from happening. Extremely lightweight at only 1.3 Oz's it adds virtually no weight to the crank which is important for balance and vibration.

Kit Includes:

• 1x Aluminum Crank Bolt Capture
• 8x Fasteners Gr. 12.9

This part fits the following BMWs:

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem. 

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking.
