BMW S58 & B58 G-SERIES & TOYOTA SUPRA A90 A91 POWER BLOCK SPACER
Designed to fit both BMW B58 and S58 cylinder heads, this unique spacer also allows you to install either a B58 or S58 intake manifold thanks to the additional mounting points integrated into the design, giving you greater flexibility for custom builds and performance upgrades.
If you’re using our CNC Innovations BMW B58 flange on an S58 engine, you still need to use the B58 intake manifold flange gasket.
The B58 gasket is approximately 1 mm taller than the S58 gasket. Although they look very similar “same same, but different” they are not interchangeable with our B58 flange. Using the S58 gasket with this flange will cause a leak.
A thermal Teflon gasket is sandwiched between the spacer to help reduce heat transfer, while the complete assembly measures 29mm thick for the perfect balance of clearance and performance.
