Bourne HPP Inlet Valve Honda S2000 F20C F-Series

Bourne HPP F20C High Performance Inlet Valve Set

Upgrade the intake efficiency of your cylinder head with this set of premium inlet valves, developed by Bourne HPP. Designed as a superior replacement for standard components, this kit ensures your engine can withstand the extreme thermal and mechanical stresses of the high-revving Honda F20C engine.

Manufactured from high-grade EN52 steel, these valves offer robust durability for high-performance intake cycles. The addition of a Pulse Plasma Nitrided coating significantly increases surface hardness and wear resistance, while the Super Polished finish ensures smoother airflow into the combustion chamber and helps prevent carbon buildup, making them an ideal upgrade for both turbocharged and high-compression naturally aspirated setups.
