CP Pistons are well-known in the racing and performance community for their robust construction and attention to detail. Each piston is designed with specific skirt profiles and wrist pin locations to minimize friction and ensure smooth operation, even under high cylinder pressures.

This set is a solid choice for anyone looking to rebuild their FA20 engine with components that can withstand increased power levels, whether from forced induction or other modifications.

When rebuilding your engine, it's important to ensure all components are properly installed according to manufacturer specifications. This piston and ring set is designed for a direct fit into the Subaru BRZ FA20, but always refer to your engine service manual for detailed installation procedures, including proper ring gap settings and bearing clearances.
