With help from Christian Aucote of alfabook.co.uk Facebook fame we are now able to offer an adaptor plate so you can fit a throttle body off a Alfa 2.5 V6 onto your Twinspark engine.
The adaptor plate fits both aluminium and plastic Twinspark inlet plenums
The adaptor’s internal bore is parallel sided so that you can gas flow it to your needs. This is easily done using a rotary burr tool
The kit comprises of the adaptor plate, two gaskets (only one is needed if you are fitting it it to a plastic plenum) and 4 fixing screws
Price is for one set as shown in the photo
