What purpose does the ceramic coating serve?
Ceramic header coatings serve a multitude or purposes- Most importantly it is protection for the header and the car. On average, ceramic coated headers operate 30% cooler than uncoated headers. Hot Rod Magazine said this about ceramic coated headers “…ambient temperatures with a heat gun in the vicinity of the headers did show a 200-degree-F temperature drop near the pipes at the pipe surface. Although the dyno numbers don’t reflect this drop, in a tight engine compartment, a reduction in exhaust-radiated heat could translate into a big power gain: On a normally aspirated engine, every 10-degree-F inlet temperature decrease increases engine power by about 1 percent.
