We designed our Silicone CCV Breather Hose / Vent Pipe as a true BMW silicone CCV hose upgrade for tired, brittle factory plastic. This OE+ BMW crankcase vent hose keeps the original routing on M54 engines while using oil- and heat-resistant silicone that survives years of daily driving and track use. 

As an M54 silicone breather hose replacement, it helps stabilize idle, reduce vacuum leaks, and cut down on CCV-related fault codes.This breather hose replaces BMW part numbers 11611432559 and 11617533398 and is designed specifically for M52TU and M54 engines. It fits E46, E39, E60/E61, E53, E85, and E36/7/8 models equipped with these engines. 

The hose is built from premium oil-resistant 3-ply silicone, paired with 304 stainless Oetiker clamps and new fittings for long-term reliability. During the presale, 25 units are available at $59.99 before moving to the $79.99 retail price. Pre-sale buyers are encouraged to review the included documentation and package contents, and the first 50 customers will also have the chance to participate in prize pack contests, with Bavhaus window decals included as a bonus.
