BMW M5 Z8 S62 Solid Lifter Bucket - Priced Each is the ideal upgrade for enthusiasts looking to push the performance limits of their BMW M5 or Z8 with the S62 engine. Hydraulic lifters, while effective at reducing noise and maintenance, can become a bottleneck at higher RPMs due to their reliance on oil, which can slow movement and increase stored weight. By upgrading to solid lifter buckets from Turner Motorsport, you can achieve higher revs and unlock more power from your engine without the drawbacks associated with hydraulic lifters. This upgrade is crucial for those seeking peak performance and reliability.

  • Enhanced Performance: Allows for higher revs by eliminating the limitations of hydraulic lifters.
  • Improved Durability: Solid design reduces the risk of failure at high RPMs.
  • Precision Engineering: Turner Motorsport quality ensures a perfect fit for BMW M5 and Z8 S62 engines.
  • Optimal Power: Maximize your engine's potential with this essential upgrade.
  • Priced Per Unit: Allows for customized upgrades based on your specific needs.

Don't neglect your motor mounts! Most stock BMW motor mounts are fluid filled and the stiffness of the mount depends on this fluid. But over time the fluid leaks out and the strength of the mount is greatly reduced. A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. As the engine is moving around it can contact other parts in the engine bay - usually cooling related. The mechanical fan can hit the radiator; the A/C compressor can hit a radiator hose, the exhaust will flex and may break. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).

This mount is for the right/passenger's side.

This is a direct replacement for the factory motor mount for M62 V8 engines and M73N V12 engines.

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.

This air pump check valve prevents exhaust gases from entering the air injection system. If the air injection check valve develops issues, then the check engine light can illuminate. This issue will cause your vehicle to release more emissions and potentially damage the AIR system. Replace your old malfunctioning valve to get your car emissions compliant again.

This is the replacement for the troublesome oil filter profile gasket on the M50, S50US, M52, S52, M52TU, M54, and S54 engines. The housing is separate from the engine block and in between there is this small profile gasket. The gasket shrinks over time which allows oil to seep out. In our own service shop, it's one of the most common service jobs we perform. One of the other common leak points is the VAN0S oil line and its seals. Since the line comes out with the oil filter housing anyway you might as well replace the line itself or at least the seals. On S54 engines (E46 M3, MZ3, Z4 M) there is a flanged head bolt going into the cylinder head, behind the thermostat cover. This holds the left side timing chain guide rail in place and if it's loose or falls out you could have a very serious engine failure to deal with. Make sure to check this bolt while you're replacing the oil filter housing seal. You only need to make sure it's tight. But if it's come loose you may want to replace the seal ring and use a small touch of oil-resistant thread sealer.

The aFE intake is made from high-quality materials, reducing underhood temperatures and not contributing to heat soak of the air filter. aFe's Stage 2 Intake uses an oiled cotton air filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, ABS plastic intake tube, sealing materials, hardware, and install instructions.

The software is tuned by BMW tuning whiz Jim Conforti and supplied with the Shark Injector. The Shark Injector is a do-it-yourself reflash tool that plugs into the OBD diagnostic plug in your dash. With the push of a button, it will copy your stock software and reflash your computer with the performance tune. You can set it back to stock at any time by following the same procedure.

Both of these items work together to bring up huge torque increases and much improved driveability. They provide a solid performance boost with a low upfront cost. For an excellent 'bang for the buck' upgrade, the software and intake are a great choice.

1999-2003 E39 M5 Stage 1 Engine Upgrade includes:
aFe Cold Air Intake
Shark Injector performance software

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.

BMW vehicles are prone to oil separators freezing in cold weather if driven before the engine is fully warmed up. This can lead to a howling noise followed by multiple oil leaks. The crankcase breather valve vents oil vapor from the engine block to the valve cover, but condensation can sometimes cause it to freeze, leading to a failure of the entire oil separator system, causing it to crack and break down. To prevent damage to your engine, it’s best to replace all components of the oil separator system at once. Replacing everything ensures reliable performance and durability. Remember to also order a valve cover gasket to make the replacement process easier.

This is an OEM Ruville Idler Pulley, also known as the roller pulley or deflection pulley. The idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).

With their individual brands INA, Luk, and FAG providing exceptionally high quality parts directly to BMW, as well as countless other automotive companies, their history of reliability and variety of offered parts makes Schaeffler a go-to replacement parts provider for all of us here at Turner Motorsport.
