Brand New MAR Motorsport inlet & Exhaust valves for Cosworth YB engine type
Plus any other YB powered vehicle!
These valves have been manufactured exclusively for MAR Motorsport Ltd by an OE valve manufacturer who specialises in producing high performance valves for many vehicle manufacturers.
These parts have been made from the original drawings and not reverse engineered from sample parts like others. They are sodium filled as per the original and are also the correct grade of steel as per the original parts. In short, they are identical in every way to the original YB0600 and YB0016 valves that the engines were built with.
Please be aware that there are valves available claiming to be sodium filled and the correct material which are quite simply not.
