Hi chris hows things?
Going to be doing my cooling system soon and as upto yet not really researched it. If the heater matrix is going to help would it be better near a cool airflow source?
So is there anything you can't find a use for...LOL
ps... Simon had the samething on his exhaust manifold (had black soot on the outside of the 4 into 1 branch) not a good thing but at least you found it.
Excellent job Chris........
