These pipes replace the plastic pipework from the turbo to intercooler and the plastic pipe between the intercooler and throttle body. The original pipes are very restrictive - the turbo to intercooler pipe is flattened down each side quite severely for no apparent reason. There is plenty of clearance between the block and the chassis for a larger round pipe. The Forge pipe is as big as you can go without the ECU reporting an error. The stock intercooler to throttle body pipe is also restrictive, being ovalised along its length, and manufactured from two pieces glued together making the inside of the pipe non-uniform.
Both the Forge pipes are manufactured from mandrel bent, highly polished aluminium tube and come with all fixings necessary. The intercooler to throttle body pipe can be complimented with our FMKTSCI throttle body hose.
