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
 

Due to weak plastic construction, the factory plastic crankcase ventilation breather hose is known to fail. After years of exposure to piping-hot engine bay temperatures and chemical-laden oil vapors, the corrugated plastic tubing can crack, crumble, or fail altogether.

We set out to bulletproof your M52/S52 CCV system with a durable silicone breather hose, designed to provide a comprehensive upgrade and permanent replacement for the factory plastic hose. By replacing the flimsy, heat-hardened OEM plastic hose with a four-ply fluorosilicone hose, you'll experience peace of mind knowing your M52 or S52 is free from the inevitable return of oil leaks, vacuum leaks, and drivability concerns that would have been.

This breather hose is found at the front of the engine, and is used to connect the cyclone separator to the valve cover. It replaces OEM part number 11151703775.

Features:

Silicone construction ensures a durable replacement that is sure to outlast OE plastic Designed as a direct replacement for the factory breather hose - not too short like many aftermarket alternatives, and does not require cutting to fit Works seamlessly with the OEM OBDII valve cover and cyclone separator, as well as the Turner Motorsport Billet Aluminum Valve Cover (T#26238386) Design:

Three-ply wire-reinforced fluorosilicone hose is designed to resist degradation due to exposure to oil vapors O-rings are pre-installed in OE Norma connectors for a lasting seal Includes pre-installed 430 stainless steel hose clamps for durability and corrosion-resistance Product Development:

Our Silicone CCV Hose Upgrade was designed, engineered, tested, and quality inspected by our Research and Development team in our Wadsworth, Ohio, facility. We strive for the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modelling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

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.
