Something for the high power BMW S54 racers and engine builders. The bottom end of the S54 block reportedly starts to fails under high power.
This cap is made of high strength tool steel, with the height modified to sit flush with the bottom surface of the block. For very easy and strong girdle fitment! It's never been easier to strengthen up the bottom end of your S54 engine!
As with all cap changes (or service), your block will need to have the main bearing surface precision machined after fitting these.
Complete set of seven caps.
Material: high strength tool steel
