All fitted now, managed to get the engine covers back on to! Really pleased with the mod. The car gets warmer quicker and by the looks of things the MPG's better?! Cant quite work that one out but its definitely better.
Also the pipe under the inlet was split, car seems to pull a bit nicer to.
After the many cuts, swear words and cigarettes. I have to say its a mod definitely worth doing if you already haven't.
And yeah, whats the point of the puck!
Will upload some pics of my handywork tomorrow
