Reliable beryllium copper cups allow proper crush sealing with installing your Mazdaspeed Di injectors


Superior design:

The groove and flared lip design allows the seal to crush into the cylinder head, sealing in the OEM location and against the side for superior sealing performance.


Clamping Force:

No studs are necessary because the clamping force does not need to be increased above factory specifications
