When we designed this catch we wanted to have the most function options available, the best separation method, and the easiest to service. The Turner engineered catch cans offer a pre-setup design based ion desired flow direction, however, this does not limit you to this flow. The inner baffle orientation can be easily adjusted to flow in both directions in case you decide to move this catch can to a different vehicle. A 4 chamber system baffle system inside the catch can was engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can. Having a closed/recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation.

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.

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. Level 1 kit includes the following; Oil separator Hose from oil separator to dipstick tube Hose from oil separator to valve cover Hose from intake manifold back to the connector hose Hose from oil separator up to the intake manifold

This secondary air shut off valve helps to reduce emissions by mixing fresh air with the exhaust. When this part fails cause a engine fault code and it will trigger a "service engine soon" light.

This is also one of the main causes of carbon build-up in the E39 M5 secondary air system. This shut-off valve can allow exhaust gas to blow back into the system where it accumulates. Regular replacement of this part will help prevent that build-up.

This item fits the following BMWs:
1996-1998 E36 BMW 318i 318is 318ti 318ic with M44 engine
1997-2003 E39 BMW M5
