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.

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 have an M3 engine and want to use the 21.5 lb/hr injectors (pink top, stock on the 2.8 M52 and 3.2 S52) we have the perfect chip for you. Instead of changing to the smaller 17lb injectors or upgrading to the full 24lb, you can use the injectors from the stock 3.2 M3. They are in-between 17lb and 24lb, allowing a little more fuel to compensate for intake and/or exhaust upgrades.Perfect for running headers with an intake! There are plenty of surplus 21.5lb injectors out there (we sometimes have them too, check out Used Parts section).

It's usually not necessary to use bigger injectors but this gives you another option in your engine planning. This software covers almost all of the popular bolt-on upgrades, including the larger HFM (Euro or 540). Choose the mods/upgrades from the list below.Turner Performance Chips provide the ultimate in performance advantage!

Note: we will not be offering this software for use with cams. More aggressive camshafts require the use of the Bosch 24lb injectors. The 21.5lb injectors are maxed out when used with cams.

Additional Options:

• EWS-delete: required when using the silver 413 ECU in a car that does not have EWS (all chassis manufactured before 12/94). If you will be using this chip in an EWS car (1/95-later) you do not need EWS-delete as nothing EWS related should be changing.
• Speed sensor delete: for an E30 with an M50 engine conversion, the signal from speed sensor does not make it to the DME, causing a low rev limit. We remove the need for the speed sensor signal to reach the DME.

This S52 OBD-I Performance Chip applies to the following BMWs:
Any S52 engine converted to OBD-I electronics
1985-1992 E30 S52 conversion

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.

• Cylinder Head Washer
• BMW Coolant / Antifreeze - 1 gallon
• Copper Exhaust Lock Nut

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 Redline D4 ATF, the transmission filter, gasket and bolts. This filter fits A4S 270R/310R automatic transmissions on BMW E36 318i 318is 318ic 318it 323is 323ic 325i 325is 325ic 328i 328is 328ic. E34 525i M50. E39 528i Z3 2.3 2.8.
