BMW Intake Parts for BMW Z3 (1996-2002)

The F-connector is located on the air intake boot and provides a connection point for the vacuum lines that run to the brake booster and fuel pressure regulator. The factory connector is made of plastic and with heat and exposure to the elements the connector becomes brittle and potentially cracks. As a result, a vacuum leak occurs which can cause poor idling issues, evap fault codes, and poor performance. 

This aluminum version from ECS Tuning is impervious to these issues, and will easy outlast the rest of your plastic and rubber vacuum system components. 

This item fits the following BMWs: 
E39 525i 530i 

E46 325i 325xi 330i 330xi

Z3 2.5i 3.0i
 

BMW S54 Silicone Throttle Body Boot Set - With Clamps is an essential upgrade for any BMW S54 engine, designed to replace aging and deteriorating rubber intake boots. Engineered by Turner Motorsport, these silicone throttle body boots provide superior durability and reliability under both street and race conditions, including boosted applications. Unlike simple silicone reducers, these boots are meticulously designed with the same internal features as the originals, ensuring a perfect factory fitment. The three-ply construction offers enhanced strength and longevity, making them slightly thicker than the factory boots. This set includes six boots and compatible clamps, providing a complete solution at a fraction of the cost of OEM replacements.

• Enhanced Durability: Three-ply construction withstands heat cycling, vibrations, and oil exposure.
• Perfect Fit: Designed with factory fitment in mind, including all internal features of the originals.
• Complete Set: Includes six boots and compatible clamps for a full replacement.
• Cost-Effective: Less than half the price of OEM replacement boots.
• Versatile Compatibility: Fits all intake plenums, including US, CSL, and replicas using OE-style boots.

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.

Flexible silicone smooths the intake tract while allowing for a range of performance intakes fitments. The ultimate in durability!

In most vehicle applications, the rubber intake elbow found in the intake system is not designed for performance or modification. They were designed to get the job done but when you add a performance filter, intake or tune, the stock elbow will start to show it weakness. The stock rubber elbows disrupt air flow as it passes over the accordion sections causing unwanted turbulence and negating the effects of intake modifications.

With high quality 4 ply construction, the Turner intake boot is strong but flexible, ensuring a secure fit on an OEM or aftermarket intake system. A smooth interior ensures unimpeded airflow, while a smooth, unassuming exterior adds to any engine bay.

Benefits:

Improved throttle response,
Increase induction sound
Increased power output - and power output, Best when paired with an ECS drop-in air filter.(ES4461001 or ES4460965)

Introduced in the late 1990s, the DISA (Differenzierte Sauganlage or differentiated intake system) valve plays a crucial role in adjusting the intake manifold's effective length. This mechanism incorporates a flap that opens and closes in response to DME inputs, optimizing airflow for both high and low RPM use.

Although the DISA system marked a significant leap in engine efficiency, it has become a common point of failure in older BMW models. The flap is secured to the body using a plastic pin, prone to degradation over time due to heat exposure. A malfunctioning DISA valve can lead to various issues, ranging from power loss to severe engine damage.

Signs of DISA valve failure include:

Audible rattling from the upper intake manifold. Power loss during different RPM/load conditions. Decreased fuel efficiency due to improper flap operation or valve failure. Illuminated SES/Service Engine Soon light, indicating lean/rich conditions or misfires (common DTCs include: P1083, P1084, P1347, P1348). Potential valvetrain damage as a result of flap pin failure, leading to plastic and metal debris circulating in the engine. If you notice any of these symptoms, it's crucial to replace the DISA valve promptly to avoid further engine complications. Continued use with a faulty DISA valve can escalate to extensive engine repairs or replacement.

Fortunately, Febi-Bilstein offers a high-quality OE DISA valve designed for seamless integration, ensuring optimal fit, finish, and functionality. Installing this valve is straightforward, requiring basic hand tools and less than an hour of your time. Restore your engine's performance and safeguard against major damage by upgrading to a new DISA valve from Febi-Bilstein.
