I had this adapter plate designed and machined for my Ford Fiesta XR2 Mk1 Duratec conversion as I couldn't find anything else that would do what I was looking for, and I simply didn't have the space for a filter housing.
It features 1/2BSP threads for suitable connectors
If you're interested in having one made, speak to BR & D Engineering in the UK, as they still have the CNC data and able to make one-offs.
