Choate Engineering pistons are designed with the factory problems in mind. As do all our products, these pistons help to solve issues with piston failures!
The polyPhen coating is a thermal barrier that resists heat and heat absorption into the piston. Which forces more heat into the cooling system via the piston rings.
By keeping the heat in the cylinder instead of the components it not only causes the internals to live longer but also gives more efficiency to the engine.
