Similar to other baffle designs this will fit the sump of either the 1.6 or 1.8 MX5's to hopefully help retain the oil around the pick-up pipe. I designed this for a standard uncut sump and it fits below the standard baffles but it could also possibly be shortened for a cut-sump.
I had two spares made in addition to one for my own car and this is the last spare. The Viton Rubber Flaps shown in some of the pictures are not included but these can be bought from ebay etc. Some minor fettling will be required to make this fit as the slots could benefit from being enlarged slightly to ease fitting the Viton flaps.
