The material choice contributes to their durability and ability to withstand the heat and pressure inside the engine. This set includes eight valves, providing a complete intake valve solution for your H22 engine rebuild or performance upgrade. They are designed to be a stock compression plus replacement, meaning they fit within the standard compression ratio while offering improved flow characteristics.
