Here we have an extremely complete s55 v8 engine with all the accessories removed from a 2015 M4 with only 7740 km, this will fit all M4/M3 with the twin turbo S55 engine, or you could swap it into something custom as it is a complete engine swap and I do NOT charge a core. Included is listed below, if there is anything else you require please let me know so I can include it, this engine is out and ready for immediate shipping.
