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

A new power steering pulley is key to keeping your steering system smooth and reliable. Over time, pulleys can warp, crack, or wear, causing belt slippage, whining noises, or even pump failure. Installing a fresh pulley restores correct belt alignment, eliminates noise, and maintains consistent hydraulic pressure for precise, effortless steering. Why choose a new pulley? Smooth operation – Ensures proper belt tension for dependable pump performance. Noise reduction – Eliminates squealing, whining, or vibration from worn pulleys. System protection – Protects the pump and steering components from damage. Install a new pulley and keep your steering system running quietly, efficiently, and confidently.

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

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!

This VAC exhaust hub is the perfect upgrade or replacement for your already broken hub. The larger engagement tabs fit the holes on the pump disk for a more secure fit to avoid the hammering of the factory hub faces that cause the broken tabs.

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. Designed using 3D scanning and CAD modeling, the Turner Motorsport VANOS Exhaust Hub Upgrade provides a tight, interference-free fit into the oil pump disc, completely resolving the issue without unnecessary labor.

Features & Benefits:

Direct bolt-on solution for S54 VANOS oil pump drive tab failure, preventing potentially catastrophic damage to engine internals Precision-machined from high-strength 4340 steel and heat-treated to match OEM specifications Designed using 3D scanning and CAD modeling to ensure precise fitment within the OEM oil pump disc Engineered to eliminate the play that exists between the exhaust hub and oil pump disc from factory Backed by extensive real-world testing and our lifetime replacement program!

Schrick has been dedicated to engine performance through the development of only the highest quality camshafts for more than 40 years. They've created a bond with BMW enthusiasts nearly the entire time, offering options for both the street and track using top materials for strength and accuracy. Schrick has grown into a technology center offering one of the most advanced locations for engine testing and manufacturing.

These cams are a direct replacement for the stock cams and give a solid 15+ horsepower boost at the top end and great midrange torque increases too! More gains can be expected with intake and header upgrades and custom software tuning. A slightly lumpy idle is expected at cold start, but will be smooth once at operating temperature.

These Schrick cams were initially developed for the M3 CSL, but they also work well on the US and other non-CSL S54 engines. With more duration, they are a great match to high-flow headers and CSL intake plenum upgrades.

KIT INCLUDES

Schrick 280-Degree Exhaust Camshaft Schrick 288-Degree Intake Camshaft 24 Turner Motorsport DLC-Coated Performance Rocker Arms NOTE: Camshaft replacement requires multiple special tools. We offer the Genuine BMW Camshaft Press (T#171829) and a Schwaben Camshaft Alignment Tool Set (T#395239) to aid in installation.

Schrick has grown into a technology center offering one of the most advanced locations for engine testing and manufacturing.

These are a direct replacement for the stock camshafts and offer increased flow at mid and higher RPMs, thanks to 12.5mm of valve lift. Unlike 288/280 camshafts, this 280/272 set does not require upgraded valvetrain parts. The profile of these camshafts is quite close to stock CSL specs.
