BMW S58 Engine

G80 M3 | G82 M4 | G87 M2

The BMW M Series S58 engine is the high performance version of the legendary B58 which is well known for delivering huge power gains with some basic modifications. BMW has provided the S58 with a much more performance orientated fuel system than the B58, giving scope for serious power gains in an already high performance engine. Commonly found in the newest generation M series.

Valve Spring Fitment Guide

Download the S58 Engine Valve Spring Fitment Guide to clear up any confusion about using the B58B30 spring kit with the S58B30 head. Despite some claims suggesting that this is unsafe due to a different retainer being required for higher lift camshafts, our guide confirms that this is incorrect. The guide is available to download now and provides clear guidance on this matter.
