Dave - I *might* have a spare black plastic "MAP" Pipe from an LCR if you want it. There's two brass inserts for the MAP to screw into, and the inserts were spinning, so I had to cut the bolt heads off. The LCR MAP needs a 12mm dia hole, I assume the Cupra's is the same.
The TT225 one is the same, except the mounting tab is wider - on the LCR they simply cut half away to get it to clear the fan housing.
IIRC Sie got Forge to knock up a complete replacement out of ally with their MAP boss welded on.
Cheers Phil, I was looking at the same think Sie did. I think I might try to avoid going under the battery tray.
While you're here though, was it you that was doing the polished LCR charge pipes?
