The engine crankcase in you car is filled with oil to keep everything lubricated, and to keep the oil inside of the engine, seals are used anywhere there is a seam in the engine, or any place a shaft protrudes from the engine. One such seal is the front main crankshaft seal. This seal is located around the the crankshaft at the front of the engine, and keeps oil from leaking out around the crankshaft. Unfortunately, over time seals will become brittle, crack and begin to leak due to their exposure to heat and oil.

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

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

Every 60-80,000 miles, we recommend replacing your spark plugs and coils 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, we have put together our High-Performance Ignition Service Kits, now featuring our very own Turner Performance Ignition Coils! These kits include our new Turner Performance Ignition Coils, new OEM Bosch Platinum+4 spark plugs, and AGS dielectric grease. The new Turner Performance Ignition Coils are designed with performance and efficiency in mind. An engine needs 3 main components to run (Air, Fuel, and Spark.) Ignition coils are responsible for 1/3 of the operation of your engine and it would be smart to weigh the options when shopping. Turner ignition coils are modified to increase energy output; more energy output results in a faster, more efficient, and consistent burn to make sure your fuel is being utilized to its maximum potential. These coils offered by Turner feature a blue housing that gives your engine the performance and aesthetic you're looking for. Features and Benefits: Increased Performance Direct Fitment Signature Turner Blue finish High Quality Bosch Platinum+4 Replacement Spark Plugs Premium AGS Dielectric Grease Included

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!

The idea of power pulleys is simple. The less effort the engine puts into running accessories such as the water pump, power steering, pump alternator etc., the more of that power can be used elsewhere - your wheels! The way this is done by reducing the rotation of the pulleys by as much as 10-20%! The end result is more horsepower at your disposal. Turner has done extensive testing (on and off the track), to ensure that the accessory systems still function as intended and without failure. These pulleys offer an excellent compromise of power gains, reliability and performance. All Turner pulleys are constructed of high quality T-6061 aluminum for durability and longevity. They are also finished in a black hard anodizing, which is highly resistant to wear including chemical and heat exposure. They have been designed to carry stock-like aesthetics, but with increased strength properties and lighter weight. Because of the durable aluminum construction, you can also put the worries of a serious plastic failure to rest. These pulleys will last, all the while increasing horsepower too! While you're installing your Power Pulley Kit, it makes sense to overhaul your Accessory Belt System as well, so this kit includes our Accessory Belt Kit as well.

Enhanced Durability: The WPC Performance Rod Bearing Replacement Kit is designed with superior materials and manufacturing processes.

This increases power and responsiveness, providing a more exhilarating driving experience. Whether tearing up the track or enjoying a spirited weekend drive, you'll notice a difference in your vehicle's performance. Precision Engineering: Crafted from premium quality materials, these bolts and bearings offer exceptional tensile strength and structural integrity. This guarantees that your connecting rods will stay securely in place, even during high-stress situations. Your engine's components will work in perfect harmony, minimizing the risk of catastrophic engine failure. Preventative Maintenance: The S54 is notorious for rod bearing failure, often necessitating complete short block replacement. Choosing to proactively replace your rod bearings with our WPC offering ensures smooth operation and eliminates potential engine failure. Included in the kit:

Take the guesswork out of S54 ownership. This all-inclusive kit targets the two most notorious failure points on the BMW S54 engine: broken exhaust hub tabs and degraded internal seals.

Turner Motorsport S54 VANOS Exhaust Hub Upgrade

The factory S54 exhaust hub is a ticking time bomb. Excessive play between the drive tabs and the oil pump disk creates a rhythmic rattling that eventually shears the tabs off, risking catastrophic engine failure.

While other kits require deep-engine surgery, our Turner Motorsport Hub Upgrade offers a "work smarter" approach.

Precision Engineering: Developed using 3D scanning and CAD modeling for a perfect, interference-free fit.

Superior Materials: Machined from high-strength 4340 steel and hardened to OEM specifications.

No Re-Timing Required: This bolt-on fix eliminates the failure point without the need to disassemble the VANOS unit or disturb engine timing, saving hours of labor.

ECS Tuning VANOS Seal Kit

The original BMW seals are made of Buna-N rubber, which quickly hardens and loses its sealing properties when exposed to synthetic oil and high heat. Our ECS engineering team has corrected this flaw.

Viton™ Upgrade: We utilize high-performance Viton O-rings for the internal seals, seal plate, and solenoid.

Chemical Resistance: These seals are designed to remain pliable and effective for the life of the engine, restoring lost low-end torque and smoothness.

ECS Tuning Rattle Repair Kit

Eliminate the dreaded "marbles in a can" sound. This kit addresses the axial play in the VANOS helical gears.

Hardened Steel: Our rings and washers are precision-ground to resist the wear and deformation that lead to engine rattle.

Silent Operation: Restores the refined sound and feel of your S54 across the entire RPM range.

The factory VANOS exhaust hub on the S54 engine is known to develop excessive play where the drive tabs interface with the oil pump disk. Over time, this imprecise fitment causes a back-and-forth rattling motion that can result in the tabs shearing off inside the engine, risking catastrophic damage or complete engine failure. Unlike other aftermarket solutions that require full VANOS disassembly, retiming, or replacement of the oil pump disk, the Turner Motorsport S54 VANOS Hub Upgrade offers a smarter approach. Our bolt-on fix eliminates the common failure point without opening the VANOS unit or disturbing engine timing.

Our solution involves removing the worn tabs from your stock exhaust hub and installing our precision-fit replacement, which is precision-machined from 4340 steel and hardened to meet OEM specifications.

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 used in M52, S52, M52TU, M54, M56, M62, M62TU, S62, and M73 engines (but may be split into specific model years, see below). 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 12131748018 replaces previous BMW part number 12139067830 and 12137599219.

Sold per coil. Connecting boot sold separately.

E46 ignition coil boot

We recommend replacing the rubber boot that connects the ignition coil to the spark plug. Sometimes a bad coil may just be a broken or damaged connector boot. This is especially true on cars with a leaking valve cover gasket where the oil has contamintated the rubber boot and the electrical parts inside. This boot can be replaced on its own without having to buy a whole new coil. This part is also useful if you purchased a coil that did not come with a new boot.

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. BE Bearings, in conjunction with Clevite, an OE bearing manufacturer, have redesigned and manufactured the bearings for greater clearance and have changed the original material composition from tin-aluminum to lead-copper. This upgrade incorporated the state-of-the-art Clevite Tri-Metal design and featured a Tri-Armor™ coating. This allows for the additional lubrication for wear prevention, plus, the softer bearings are better for your engine and are more tolerant of foreign particles suspended in your oil. Another benefit from this is that the oil can now be sent for testing to accurately gauge the amount of wear occurring in the engine. Kit includes Upper and lower BE Bearings upgraded rod bearings for extra protection against wear Hardware Oil filter Castrol TWS Edge Professional Oil pan gasket Oil pan cover gasket RedLine assembly lube

Keeping the oil inside your engine is extremely important to performance. Between oil change intervals, your oil can dip to dangerous levels if there is a leak you may not be aware of. The valve cover is an extremely common place for this to happen. Years of exposure to extreme temperature change degrades the cover and the gaskets and causes failure. Replace yours to keep your engine oil in your vehicle.

Replace all the components of the oil separator system together 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. 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. ur Level 1 kit includes the following; Oil separator Hose from oil separator to dipstick tube Hose from oil separator to valve cover Hose from intake manifold back to the connector hose Hose from oil separator up to the intake manifold

A bad DISA valve can cause a variety of issues, from a loud racket in the engine bay, hesitation at low rpm and a rough idle with lean codes. If the valve is making a loud noise, we recommend replacing it as soon as possible. It is possible for the pin holding the flap to be sucked into the motor causing serious damage. Very easy to replace, just need to undo the 4 bolts holding it to the intake manifold. Includes new mounting hardware
