Perfect. I'll certainly give it a try! I didn't manage to do the plugs as I didn't have a medium extension for the socket set. I only had a long one which is fine for cylinders 2, 3, 5 and 6, but for 1 and 4 it was too long. I didn't want to mix the plugs either as the BERU ones had 4-points on them, and the temporary replacements I have are NKG 3-points. Wasn't sure if you could mix them, so I didn't change them at all.

I've got the extension now so I'll get right on it weather permitting!

I didn't think the later 3.2 S engines had tubes?
