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.

Replacing the rod bearings requires mechanical knowledge and skill, a clean workspace, and several specialist tools. Our preferred procedure is to leave the engine in the car but remove the front subframe. The engine must be supported from above with an engine brace. Removing the front subframe involves disconnecting the control arms and steering rack and steering column. The oil pan can then be removed and you can access the connecting rods and bearings. Replacing the rod bearings themselves is straightforward but patience and forethought will be extremely helpful. In addition to analyzing the severity of the rod bearing wear, the crankshaft must also be inspected closely for damage. Rod bearings that have been severely worn may have damaged the crankshaft (requiring replacement or machining).

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.

Now that BMWs popular S54 engine (found in the 2001-06 BMW M3, 2001-02 MZ3 and 2007-08 MZ4) are getting older, it's important to keep an eye on particular items. One such point is the S54 Vanos oil line. Normally thought of as a worry-free item, it has proven to put the damper on many track days. Rogue's stainless steel braided VANOS line replaces the factory BMW part number 11367837614 (current MSRP from BMW is $128.08!) The high pressure (1200psi) control system of the S54 vanos system is used to ensure responsive and accurate camshaft adjustments. The added complexity of the high oil pressure used on the S54 vanos means more opportunities for failures. Some customers have encountered the high pressure hardline fail at the track, spraying oil all over their engine compartment, ending their day. Rogue Engineering's S54 Vanos Oil Line is built in their Upper Saddle River, NJ facility, and tested to over 3000psi. Using their stainless steel braided hose with the proper banjo fittings, this a direct replacement for the factory line. Like the factory line, the lower portion of the line uses a heat sleeve from additional heat from the VANOS pump itself. Fits the following BMWs: 2001-06 BMW E46 M3 2001-02 BMW MZ3, including coupe and convertible 2007-08 BMW MZ4, including coupe and convertible

The S54 engine has a known history of rod bearing failure, and if your engine is higher mileage, don't let this catastrophic failure happen to you. Replace your rod bearings and prevent a spun bearing which can trash your crankshaft. WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both. Kit includes Upper and lower WPC treated rod bearings for extra protection against wear Hardware Oil filter Castrol TWS Edge Professional Oil pan gasket Oil pan cover gasket RedLine assembly lube Connecting rod bolts

Not only will this kit stop most E90 oil leaks, it's the perfect addition for ignition coil or spark plug replacement! Oil leaks - and the damage they can cause - seem to be the worst annoyances on these cars. The biggest source of an oil leak is from the valve cover, followed by the oil filter housing, Valvetronic seal, camshaft seals, and the eccentric shaft sensor seal. Once the oil leaks, and if ignored for an extended time, the oil will contaminate vital electrical sensors. This is especially the case with ignition coils and also the eccentric shaft sensor on the Valvetronic shaft at the top of the cylinder head. During any ignition coil and spark plug replacement take a close look inside for any oil pooling at the bottom. We have been seeing valve cover oil leaks as soon as 40,000 miles. We look for oil leaks on every E90 that comes into our shop.

We have put together this package of valve cover gaskets and other related gaskets and seals for you to fully overhaul the N52 valve cover and put a stop to those pesky oil leaks. This package has the replacement parts for N52 engines built from the 2007 model year and includes:

  • 11127582245 - N52 valve cover gasket set
  • 11127552280 - N52 eccentric shaft sensor seal
  • 11127559699 - N52 Valvetronic gasket

2007 and later N51/N52 engines do not need replacement valve cover bolts, unless the bolts are actually broken off or missing. Unlike the 2006 aluminum hardware, the later parts are steel and not 1-time use.

These are all OEM or OE parts. Replacement of these gaskets and seals is straight-forward but a long process. BMW dealers typically charge for over eight hours of labor. If you have replaced spark plugs before you should be capable of this repair. In addition, there are several other parts to replace while you're in the vicinity: camshaft sensor o-rings, oil filter housing profile gasket, VAN0S solenoids, and the eccentric shaft sensor. These other parts, except the eccentric shaft sensor (see below), are replaceable without removing the valve cover but are more easily accessed during the valve cover work.

Eccentric Shaft Sensor: This is the position sensor that relays the eccentric shaft's position back to the DME. It's located at the front of the engine and is only accessible with the valve cover off . The seal around the sensor can fail and allow oil to blow out from under the cam cover. Oil can then leak into the sensor itself and cause it to fail. Without a functioning sensor your E90 can experience poor running, hesitation, poor performance, jerky shifts, and sluggish response. It's easy to check and see if oil has accumulated inside the sensor: unbolt the engine trim cover (the outer cover with the BMW roundel), unplug the sensor, and look inside. If oil is present inside or even around the sensor itself, plan on replacing this sensor during your next ignition coil, spark plug, and/or valve cover gasket work.

This valve cover kit fits the following BMWs:

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace this and all the other components of the oil separator system to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable. 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.

Over time, your engine timing components begin to wear out. Tensioners weaken, chains can stretch, and timing chain guides can wear down. All of these lead to the possibility of the timing chain jumping teeth on the sprockets, causing your timing to shift. This could result in rough idle and reduced engine power, or even complete engine failure. Prevent damage to your engine with new timing components, such as this IWIS timing chain tensioner. Note, we recommend replacing timing components every 100K miles, or sooner, depending on the condition of the timing components.

When these gaskets leak you'll start to smell oil burning when the engine is hot. Also everything downward from the top of the engine becomes coated in a greasy film. The valve cover gasket keeps all of the motor oil inside your engine. Your valve train and lifters get soaked with oil to keep everything lubricated. If the valve cover fails, engine oil seeps and leaks out, running down and burning on the block or cylinder head. Replace it and keep your engine compartment clean and tidy with all the engine oil in the motor. If you are removing your S54 valve cover for valve adjustment, inspection or repairs, you can now get all the gaskets you need in one box. Included are Valve cover gasket Spark plug seals Nut seals Grommets Copper sealing washers

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.

Rogue Engineering has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This allows for perfect operation in daily driven vehicles without a hiccup or stutter. However, when the demand for power is requested, the power pulley kit allows for the freed power to become apparent.  The term "power" pulley is a bit of a misnomer. Underdrive pulleys actually free up power by reducing the drag caused by the accessories.  These pulleys are based off a calculated percentage from factory dimensions, so that particular component speeds are safely reduced without affecting their true purpose.

Rogue Engineering Power Pullies are CNC machined from 6061-T6, heat treated aluminum and specially coated with a MIL-A-8625 Type III hard coat anodize finish. This kind of anodizing is not to be confused with a Type II cosmetic anodize finish (typical colors such as red, blue, silver, green, etc.). The hard coat anodize finish actually builds a small surface layer on top of the aluminum, preventing wear.

This part fits the following BMW engines:
S54

This part fits the following chassis:
E46, Z3, Z4

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 OEM quality components, replacing any potential fault points in your ignition system for peak performance!
