Product Description

The factory 2001-2005 main bearing support plate (MBSP) replaced the baffle plate on 1994-2000 BP motors which did not bolt to the main bearing caps, which always had threaded bosses (except for the center #3 cap).

Bolts to 4 of 5 main caps. Can be retro-fitted on 1994-2000 motors, but requires a 2001-2005 oil pan (or a modified 1994-2000 oil pan).

MiataRoadster can customize the factory MBSP to bolt to all 5 main caps for those upgrading to Pro-Gram Engineering billet main caps (which have threaded bosses on all 5 caps).
