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. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

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. 

The GENIUS5 is an exceptional addition to our lineup boasting incredible power, top-notch performance, energy efficiency, and a compact design. The GENIUS5 is a versatile 6-volt and 12-volt charger, maintainer, and desulfator with a 5-amp rating. It's engineered for use with lead-acid batteries in automotive, marine, and deep-cycle applications, covering flooded, gel, AGM, maintenance-free variants, and even lithium-ion batteries.

Features:

• Do more with Genius - Designed for 6-volt and 12-volt lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries.
• Enjoy precision charging - An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates.
• Charge dead batteries - Charges dead batteries as low as 1-volt. Or use the all-new Force Mode that allows you to take control and manually begin charging dead batteries down to zero volts.
• Simple to set up and use - Plug-in, connect to the battery, select a charge mode, and start charging your battery. A fully-automatic, worry-free battery charger for year-round use.
• Restore your battery - Detects sulfation and acid stratification and restores lost performance for stronger engine starts and extended battery life.
• Compatible with all types of vehicles - Charge and maintain cars, motorcycles, lawnmowers, ATVs, tractors, trucks, SUVs, boats, classic cars, hot rods, and more - you name it.

The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.

This is a NEW alternator from the OEM manufacturer, Valeo. No core charge applies.

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.
