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.

BMW N63 4.4L Vent Pipe

The BMW N63 4.4L Vent Pipe addresses common issues with oil separators freezing in cold weather conditions. This problem often occurs if the vehicle is driven before it is fully warmed up, leading to a howling noise and multiple oil leaks. The crankcase breather valve in the vent pipe purges oil vapor from the engine block into the valve cover. However, condensation can sometimes cause the valve to freeze, which may result in the oil separator system failing, cracking, or disintegrating. This replacement vent pipe ensures proper function and prevents costly damage by maintaining the integrity of the oil separator system.

Benefits:

• Prevents Freezing Issues: Reduces the risk of oil separator failure in cold weather conditions.
• Eliminates Oil Leaks: Helps prevent leaks caused by frozen oil separators.
• Ensures Proper Ventilation: Maintains effective purging of oil vapor from the engine block.
• Durable Construction: Built to withstand harsh weather conditions and engine stress.
• Direct Replacement: Designed to fit seamlessly with BMW N63 4.4L engines.
