Careful if you're running power steering on the Mk1...
Matteh's was wrapped, he had a small power steering leak and it all set on fire!
Never noticed any difference performance wise or temps tbh
Heard about the fire risk thing before. Bag of offcuts i had was impossible to burn. Maybe its just cheap stuff where the risk is??
IMO makes f**k all difference to anything apart from the heat coming from the manifold.
Im running it on mine due to the manifold being VERY close to the brake lines on the Mk1 shell
