Engine block strengthening plate & windage tray. Bolts to main bearing caps & sump mounts and improves torsional rigidity and reduces oil drag on the rotating crankshaft. 105 blocks with 140bhp+ can twist and cause bearing failure. This plate reduces twist & helps prevent oil starvation - for 2000 engines.
Now made from stainless steel.
To fit -
First fit the bearing caps, then the original washers and nuts for the bearing caps. Then fit the windage tray with a slim M10x1 nut (6mm max. high).
NOTE - the plate replaces the gasket so best to use a sealant around the edge.
