When tasked with specifying the ultimate N/A piston set for a customer’s M50TUB25 race engine build, this was the result.

Intended for use with a B25 crankshaft and 140mm rods, this set is also suitable for any M5X build with the correct combination of components. In the intended application, they have been specified for a 12.0:1 compression ratio and a 2584cc capacity. They also feature an additional millimetre of valve relief depth for use with high lift/long duration camshafts.

Priced as a set of six pistons, including rings/clips/pins in CP Carrillo’s usual outstanding quality.
