Forge Motorsport’s Silicone Turbo to Intercooler Pipe for the F2X M135i and M235i, replacing the weak and failure-prone OE rubber part.

The OE coupler can perish over time and lead to boost leaks and a loss of performance. Forge Motorsport’s replacement uses CNC alloy couplers along with silicone piping for a permanent solution that can handle seriously increased boost pressures, but is just as at home on a completely standard vehicle.

Forge’s Boost Hose is also recommended.
