Turner Motorsport Silicone PCV Hose for BMW M57

Upgrade your BMW M57 engine with our Silicone PCV Hose, a premium replacement for the fragile, failure-prone factory hose. Over time, the stock rubber hose deteriorates due to constant exposure to heat and oil, leading to cracks and leaks. Our solution? A high-quality silicone hose engineered for superior durability and long-term reliability.

To further enhance performance, we’ve lined the hose with fluorosilicone, providing exceptional resistance to oil and chemical degradation. Designed in-house using advanced CAD modeling and 3D scanning, this hose offers a precise OEM fit while eliminating the common weaknesses of rubber construction.

Each kit includes stainless steel hose clamps for a secure, hassle-free installation. Whether you’re replacing a worn-out PCV hose or upgrading for added peace of mind, this premium solution ensures your BMW M57 runs smoothly and efficiently for years to come.

Features:

Direct OEM Fit – Retains factory hose dimensions while eliminating reliability issues.
High-Performance Silicone – Resists heat-related wear for long-lasting durability.
4-Ply Fluorosilicone Lining – Superior protection against oil and chemical exposure.
Stainless Steel Clamps Included – Secure installation and extended service life.

The factory rubber/plastic hoses become brittle and crack over time. Brittle and cracked hoses can cause multiple vacuum leaks that are impossible to repair without hose replacement. Vacuum leaks can cause many problems including rough running, missing, stalling at idle, and even a no-start condition.

The factory hoses offered through BMW are plastic and will yield the same results of becoming brittle and damaged over time. Our solution is a premium replacement that will outlast everyone of the OEM replacements. Our Silicone Crankcase Vent Hose can be used to replace the factory brittle hose to ensure your S54 is free from vacuum leaks and performing properly.

CSL Vent Hose (11157833649) - Silicone Crankcase Vent hose is a direct replacement

Key benefits:

Lifetime replacement of the brittle OEM plastic crankcase breather hose that is susceptible to cracking overtime from constant heat cycling

Design:

Retains OEM hose end fittings to ensure proper seal

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.

Our catch can was also designed with the idea that the cans fill level can easily be checked with a top mounted dipstick and an optional use bottom drain hole. The drain system comes complete with a valve and hose to be mounted at a lower area of the vehicle so when you're doing an oil change you can drain the catch can.

Features:

  • 6061-T6 billet machined body, anodized black for lasting protection and appearance
  • Strategically positioned 4 chamber baffle system maximizes oil / air separation 
  • Knurled and black anodized oil dipstick makes inspecting oil volume of reservoir clean and simple
  • Sealed with a pre-installed viton O-Ring
  • Includes 2.5mm allen key to remove baffle plates for cleaning
  • 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
  • Closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation
  • Optional use drain hole - drain kit included!
  • Universal mounting kit

The factory rubber/plastic hoses become brittle and crack over time. Brittle and cracked hoses can cause multiple vacuum leaks that are impossible to repair without hose replacement. Vacuum leaks can cause many problems including rough running, missing, stalling at idle, and even a no-start condition. Replace the brittle or broken line that attaches between the oil separator and air box. Our Turner Silicone Crankcase Hose can be used in place of both the standard and CSL intake boxes.

Our engineers at Turner sought out to solve the degrading issues that happens with the factory crankcase vent hose and found the best solution is a silicone replacement. Our Turner Silicone Crankcase Vent Hose can be used to replace the factory brittle hose to prevent vacuum leaks and lackluster performance. Simply take your factory crankcase vent hose and remove the ends; the factory ends can be installed on the new Silicone Vent Hose with the supplied clamps for a tight seal.

- Design:

Turner logo forward facing when hood is open
