BMW Intake Parts for BMW Z3 (1996-2002)

This kit includes everything to fit an OBDI M50 manifold to an OBDII M52 or S52 engine (1996-1999). It takes the guesswork out of adding the M50 manifold to your engine. The kit includes a CNC machined adapter, with all hardware and gaskets, that allows the freer flowing M50 manifold to be installed while maintaining full function of M52/S52 components including factory PCV cyclone / oil seperator valve. No vacuum leaks, no check engine lights. And the entire kit is completely reversible. Turner Motorsport has dealt with the problems from other kits and this adapter block is by far the best solution.

The base price of this kit does not include the M50 manifold. You can pick up a used manifold from a 1992-1995 E36 325i or a 1995 M3 3.0 liter. You can find them in local junk or scrap yards, online at Craigslist or eBay, or from various forums. If you would rather not deal with the potential pitfalls of a used part, we can offer a new Original BMW manifold to go with the adapter. While expensive, the new manifold is guaranteed to be in perfect condition with no cracks, warping, or foreign objects hidden inside. A new factory BMW manifold can be added to your order by selecting the option above.

With the introduction of the 1996 model year came the OBDII emissions compliant engine. Among the many changes the OBDII engines received was a more restrictive air intake manifold. Where the older M50/S50 engines continued to make power up in the higher RPMs, the newer M52/S52 ran out of breath, limiting high-end horsepower, but boosting low-end torque. Converting the OBDII cars to the 1995 and earlier OBDI manifold is a popular modification to remove this high-rpm restriction.

To best maximize the horsepower gains of this modification, you should be using the M50 manifold with bigger cams, HFM, injectors, and software. We have found this combination of upgrades and software to yield the best results for producing top-end power. Note: using the M50 manifold shifts the power band higher in the RPM range. This is GREAT for track cars but not well-suited for street cars where the OBDII manifold works best to produce torque at lower RPM. Presently, we do not have software tuned for only the M50 manifold without cams or the HFM upgrade. Check our website again for future product releases. We currently offer custom mapped Shark Injectors for these packages:
E36 M3 - 3.5" HFM/24lb injectors/Schrick cams/stock OBDII manifold
E36 M3 - 3.5" HFM/24lb injectors/Schrick cams/M50 manifold

Optional fuel rail cover. The standard M52/S52 fuel rail cover is too tall for the M50 manifold and does not have the proper brackets for securing it in place over the fuel rail. We can correctly modify the stock M52 fuel rail cover for you to complete the factory appearance.

BMW E46 Crankcase Pressure Regulator Valve | S54 3.2L Engine is a crucial component that ensures proper crankcase ventilation by regulating oil vapor flow into the intake manifold, preventing excessive oil consumption and buildup. Designed specifically for BMW E46 models with the S54 3.2L engine, this valve helps maintain engine efficiency and performance. BMW engines are known to experience oil separator freezing in cold weather if not fully warmed up, which can lead to howling noises and oil leaks. To ensure a thorough repair, replacing the valve cover gasket when changing the separator is highly recommended.

• Regulates crankcase pressure to prevent excessive oil consumption
• Helps maintain proper engine ventilation for peak performance
• Reduces the risk of oil separator freezing and associated leaks
• Direct-fit replacement for BMW E46 models with S54 3.2L engine
• High-quality materials ensure durability and long-lasting performance
• Recommended to replace the valve cover gasket for a complete repair

Protect your BMW's engine from excessive oil consumption and leaks by replacing a failing crankcase pressure regulator valve with this premium-quality replacement.

A bad DISA valve can cause a variety of issues, from a loud racket in the engine bay, hesitation at low rpm and a rough idle with lean codes.

If the valve is making a loud noise, we recommend replacing it as soon as possible. It is possible for the pin holding the flap to be sucked into the motor causing serious damage.

Very easy to replace, just need to undo the 4 bolts holding it to the intake manifold.

Suction Pump is a crucial component for maintaining optimal vacuum pressure within the engine and brake systems of BMW models.

Designed to meet or exceed OEM standards, the Suction Pump provides a precise fit and dependable performance for long-term durability. Available through Turner Motorsport, this pump is an ideal replacement part for BMW owners looking to restore the reliability and performance of their vehicle.

• Designed specifically for BMW models to ensure a perfect fit
• Maintains proper vacuum pressure for engine and brake system efficiency
• Improves overall vehicle performance and brake response
• Manufactured from durable, high-quality materials for long-lasting use
• Direct-fit replacement for easy installation
• Meets or exceeds OEM specifications for reliable performance

The TMS E36/Z3 6cyl Intake Tube Plug is intended to be used in a variety of applications ranging from ASC delete, deleting the idle control valve in a car with a aftermarket engine management system, re-routing the PCV hose to a catch can, aftermarket supercharged engines, or simply plugging one of the hose provisions in the E36 6cyl intake tubes. It also works great as a coolant hose plug. The diameter of the tip is 20mm (just over 3/4"). A low profile Oetker compression clamp is included. The plug can be drilled and tapped for a small air temp/water temp sensor, pre throttle body vacuum/boost/MAP sensor barb, or water alcohol/nitrous/methanol injector or barb. Works with M50, M50TU S52, M52, S52 throttle boots and may work in other applications with a 20mm hose.
