Ceramic Coated Exhaust Manifolds
I've been running the car with the coated manifolds for over a year now, and I'm convinced the ceramic coating has reduced under-bonnet temperatures. I also think it has helped reduce fuel percolation, which was an occasional annoyance when restarting the car. The coating is also very tough, with no evidence of chipping, flaking or discolouration. The dark grey colour has also remained unchanged.
