BMW 335d Silicone Intercooler Boost Hose E90 E91 E92 E93
Upgrade your BMW 335d intercooler system with a reinforced silicone intercooler boost hose designed specifically for the E90, E91, E92 and E93 3 Series. The factory rubber hose on the 335d is a known weak point that often fails under high boost pressure. This high quality fluoro-lined, multi-layer silicone hose is built to handle the pressure, heat and oil mist of daily driving and performance use, helping to eliminate both boost leaks and oil leaks.
We use this hose on our own cars and customer builds, and feedback has been consistently positive for reliability, fit and performance. If you are chasing a boost leak on your 335d or you want a preventative upgrade before tuning, this is the go-to 335d intercooler boost hose replacement.
