The idea is to spray this specialized coating on components such as exhaust manifolds that get hot. The coating can dramatically reduce the temperatures of the component. Upon further examination ...

Coating parts like exhaust manifolds will improve engine efficiency by keeping the ambient temperature of the engine bay down, a by-product of which is lower intake plumbing temperatures.

Bolted directly to the engine block, the exhaust manifold is the first section of a vehicle’s exhaust system. It funnels exhaust gases from all the cylinders and routes them to the car’s ...
