Forge Motorsport replacement turbo outlet hose for BMW 3 E90/E91/E92/E93 335d

The combination of heat, oil and boost pressure at the turbocharger outlet exposes a common weakness of the original turbo outlet hose. The wall of the original hose and the metal connectors degrade over time, which can cause the hose to fail and lead to a related loss of boost pressure and power. Replacing it with an original BMW part can be expensive.

The Forge Motorsport solution is a 4-ply silicone hose with a fluoro lining, designed to withstand the typical temperatures and pressure, as well as the corrosive effect of oil at the connection at the turbocharger outlet. CNC-machined aluminium couplers ensure a precise fit.

The kit is not supplied with the male coupler O-ring. For installation onto the Forge Motorsport coupler, the original O-ring must be removed from the original male coupler and reused. If replacement is required, the original O-ring can be ordered from BMW under part number 11618506786 or 11617791470. These are the original and superseded part numbers; both O-rings are of the same quality and size.

Important: the hose must be installed according to the procedure described in the installation instructions. Otherwise, it will appear to be too short. The original O-rings and other seals must be retained.

Suitable for: BMW 3 V (E90/E91/E92/E93).
