Forge Motorsport Multi-Ply Silicone Engine Breather Hose

Secure your commercial vehicle's engine breathing circuit and prevent oil mist saturation with this premium replacement silicone breather hose from Forge Motorsport. Tailored exclusively for the Volkswagen Transporter T5 equipped with the popular 1.9 TDI diesel engine, this hose replaces the weak factory rubber component. The original factory breather lines are subjected to intense mechanical stress, hot oil vapor saturation, and cyclic under-bonnet heat. Over extended mileage, this environment causes the stock factory rubber to soften, sweat oil, swell, and eventually split apart, resulting in messy oil leaks and unmetered crankcase ventilation tracking.

Advanced Fluorosilicone Core Shielding Matrix

To eliminate this common factory weak spot, this high-performance replacement hose is engineered with an advanced multi-ply high-density fabric reinforcement weave matrix. The defining technical feature is the integrated inner lining made from premium modified Fluorosilicone. This high-end layer provides absolute chemical immunity against hot oil mist, aerosolized diesel fuel vapors, and aggressive crankcase blow-by gases. By preventing these contaminants from attacking the structural layers, the hose maintains its flexibility and wall density over decades, outlasting original rubber parts.

Generic Aesthetic Configurations & Style Finish

This uprated engine oil breather hose is manufactured to complement any custom under-bonnet design, subtle stealth Black. Optimised structural designs, technical wall densities, and high temperature thresholds, enhancing your engine bay technically and aesthetically while carrying a limited lifetime warranty.
