New Oil filter adaptor, internally modified for the larger (than original) oil drilling / galleries as per specialist memo regarding oil gallery sizes, flowed at each entry / exit point to block, corrected oil gallery alignment to the filter head.

Externally as original, marked with C52189 on the back side as original

This housing saves us 2.5 hrs of mods on the original adaptor to increase oil gallery sizes, increase flow in & out of the housing, it also saves you learning how to do drill & modify the housing out without wrecking it, there isn't much room between the bores !

Note: we can modify this adaptor for oil cooler fittings if required, at an extra charge & another part
