The 449hp BMW 650i F06/F13 runs the 4.4 32V twin-turbo V8 N63B44B, built from 2012 to 2017. This page brings together the uprated parts available for that block.
Three references make it up, all intended for V8s assembled from 2011 onwards. The head gasket comes as a Cometic MLX in 90.0mm and 1.02mm thickness or an Athena O-ring in 90.5mm and 1.10mm; it is sold individually and therefore ordered in pairs. Big end bearings come as ACL Race without treatment or King Racing with pMaxKote coating, main bearings from ACL Race and King Racing. Sizes run from standard to +0.25mm, HX clearance included.
