Introducing the Manley Performance 11891-8 BBM R/F 1.810in Exhaust Valves, a high-performance upgrade for your engine's exhaust system. These valves are specifically designed for racing applications and deliver superior flow and durability compared to OEM valves.

They are designed to work with engines that utilize 1.810in (46mm) exhaust valve heads, making them an excellent choice for engines commonly found in Formula Ford and other racing series.

In summary, the Manley Performance 11891-8 BBM R/F 1.810in Exhaust Valves are a high-performance upgrade for racing engines, offering superior flow, durability, and power output compared to OEM valves.
