BMW 5 Series E34 (1987-1995)

Upgrade to wheel studs from bolts for an enhanced connection and easier wheel installation. Racing entities often require wheel studs for better wheel-to-hub contact, offering improved confidence during high-speed performance. Turner Motorsport's wheel studs are designed to accommodate various spacer widths effortlessly, simplifying the setup process. Discover why this switch from bolts to studs can make a significant difference:

• Simplifies spacer usage with a single application designed for various spacer widths
• Wheel studs act as a wheel hanger, easing wheel installation
• Reduces constant wheel bolt removal, minimizing wear on wheel hubs
• Facilitates quick and easy tire changes as the studs stay in the hub
• Recommended torque of 15Nm with thread-locking compound during installation
• Compatible with spacers up to 20mm in size

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!

The fuel pump is held into the tank with a retaining lock ring. Most people would take an extension or punch and tap out the ring with a hammer. But that's the wrong way to do it. You could damage the lock ring, or worse, the tank itself. This handy tool is toothed to match the lock ring and takes a standard 1/2 drive ratchet or small extension. Twist the ratchet and the lock ring comes un-done cleanly and smoothly. A hefty tool that pays for itself over and over. Fits most BMWs from 1988-2013. Also has application for MINI and Porsche.

This metal screw ring tightens down to old the top of the fuel pump or fuel filter assembly dependent on model of vehicle.

Together they make this job simple and easy and ensure a tight fit with a new ring. 

Adding a Turner Performance Chip gives you the biggest bang for your buck! Jim Conforti tuned these chips on the dyno to boost mid range torque and increase horsepower in the upper RPM range. While not exactly producing V8-levels of torque you will definitely like the 38ft-lb increase at 3500 RPM - right at the start of the power band. The best thing is that there is NO downside to installing a TMS Performance Chip. Turner Motorsport has been in the BMW chip business for close to 10 years and all chips are dyno-tuned to achieve optimum performance and safety. As an added feature, the top speed limiter is removed. Premium 91+ octane fuel is required.

If you're looking for a significant bump in power you need not look any further than a TMS Performance Chip. Designed to maximize the advantage of premium fuel, Performance Chips safely alter the fuel and timing maps which results in more power and a smoother engine. These chips were tuned by Jim Conforti on the dyno with fantastic results. What you feel is more power starting at 3500 RPM and continuing up to the new rev limit of 7000. There is no downside - only an awakened engine and a car with new life!

Performance software is the key to unlocking the power that BMW left on the table. For the US market the factory software is set for 87 octane fuel. But the engine is capable of producing so much more! We make adjustments to the fuel, ignition, and camshaft timing data at part throttle and full throttle to take advantage of premium 91+ octane fuel. We dial in the settings so that more power is made at all RPM. What you'll notice is more power and torque at wide open throttle and even when driving around town. The engine will run smoother with better throttle response and less hesitation. We keep the factory safeguards in place so there is no long term engine damage or negative side effects. It's not just gaining power back - it's better than when it left the factory!

We're also able to tune for all of the popular M50 engine upgrades -

• lightweight flywheel - adds 100 RPM to idle
• stock E36 M3 camshafts - these work GREAT for producing more top end power. We adjust the maps to take advantage of higher lift and duration
• sport exhaust - additional tuning for cat-back exhausts​

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

See kit contents below for a complete list of included components.

Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. This kit includes Pentosin ATF-1, the transmission filter, gasket and bolts. 

Kit Includes:

• Automatic transmission filter with associated hardware
• Oil pan gasket
• Drain plug with sealing washer
• Fill plug with sealing washer
• 5 liters Pentosin ATF-1 automatic transmission fluid
