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.

For the 2007 model year BMW switched to a plastic valve cover on the N51 and N52 engines. As we have seen over time the plastic can crack which leads to oil leaks, vacuum leaks, poor running, and other issues. Unfortunately, it's not just the gasket that needs periodic replacement but the entire valve cover itself. This kit includes a new valve cover, gaskets, eccentric shaft seal, and hardware. The valve cover also incorporates the oil separator which is not a replaceable item on its own. So a complete valve cover replacement will tackle multiple problem areas at once. The valve cover is the same for N51 SULEV and N52 engines.
Cracked Valve Cover. The plastic used for the N52 valve cover is thin and weak in certain spots. This makes it prone to hairline or larger cracks that will leak oil and cause vacuum leaks. You might also notice rough running, especially at idle. Often a technician will go looking for a failed ignition coil, spark plug, or failed vacuum hose on the engine. And without a fault code to assist in diagnosis this can often mean wasted time and money. A cracked valve cover is a new problem area that many techs don't think to check.
Oil Separator/Crankcase Vent. BMW integrated the oil separator system into the valve cover on these later engines. An internal manifold creates a cyclone effect and centrifugal force separates vapor from the liquid oil. The liquid oil is supposed to drain through the valve cover and back to the oil pan while the remaining vapor is burned up during combustion. It's a very efficient and environmentally-friendly design with very few moving parts. Unfortunately it's not perfect and eventually the internal passageways will become clogged. This problem is made worse in cars that have short drive cycles, sit for long periods of time, do not have frequent oil changes, do not see regular runs to redline, and cars in freezing climates. If the engine never reaches optimal operating temp the oil remains in liquid form or becomes sludge. This is bad news for the entire engine, leading to fouled spark plugs, rough running and misfires and even premature failure of catalytic converters and oxygen sensors. Since the oil separator system in the valve cover is not available on its own, and cleaning it is nearly impossible, the complete replacement of the valve cover is the only option. Other oil vent tubes and vacuum hoses are also recommended to get replaced at the same time.
Valve Cover Gaskets. As with any rubber part, failures occur when the rubber becomes dry and brittle. The pliable rubber no longer forms a seal between the cylinder head and valve cover where it will develop an oil leak. Valve cover gaskets that leak can allow oil to seep into the spark plug holes and contaminate ignition coil boots and plugs. That can lead to rough running and misfires. A new valve cover includes new gaskets.
Eccentric Shaft Seal. The seal for the eccentric shaft sensor is a known spot for oil leaks. When the seal to the valve cover fails oil can end up in the sensor itself and ruin the sensor (an unecessary $300 expense). Usually a new seal (o-ring) will stop the leaks but sometimes the valve cover is at fault too. A new eccentric shaft seal is included.
All new hardware is included to avoid re-using and over-tightening the original bolts (they have a very low torque rating).
Replacement requires accessing the rear of the engine with a lot of the upper plastic shrouding removed. The vent hose on the valve cover should be replaced as it is almost always broken anyway (#11157559528). The metal fuel line must also be removed and disconnected from the fuel injectors. Professional installation is encouraged if you have never done this kind of work before. Serious DIY types should have a Bentley Service Manual to use which greatly explains the process. You may also want to combine this work with the oil filter housing gasket replacement.
There is no maintenance or replacement interval for the N52 valve cover. However, we have seen cracks and other failures in the 50,000-90,000 mile range. Our best advice is to plan on a major top end overhaul around the 70-80,000 mile mark. There's no mechanical downside to replacing it as prevention and it will make the engine run better and last longer.
