After having endless issues with the Intercooler piping popping off the throttle body we decided to search around for an aftermarket alternative.
In the end we sourced the X3E Motorsport Intercooler Piping Kit. The kit included all hose clamps and the fittings for the vacuum lines near the throttle body. Thankfully the piping came through just in time as the plastic OEM section of the Intercooler Piping had developed a rather large crack along the bead where it clamps to the throttle body.
We also took the opportunity to change out the Air Filter which was filthy and give the engine bay a general clean up.
