BMW forged pistons

Choose BMW forged piston kits by engine code, bore diameter and compression ratio. Browse piston options for turbocharged B-series and N-series builds and naturally aspirated or competition M engines. Wössner and ZRP piston listings show the specification for each application.

Check your BMW piston specification

Confirm the exact engine code and generation before ordering. Check the measured bore, piston pin size, compression ratio and whether the kit matches your crankshaft and connecting rods. Parts listed for one version of an engine may not suit another. Review each product for kit contents and installation requirements.

We also supply connecting rods, race bearings, gaskets, valvetrain parts and fasteners for BMW engine builds. Contact our UK team with your engine code and build specification for help choosing parts and checking availability.
