Gipsy Major Ignition Harness

Getting 14mm sparks for the Gipsy Major engines had always been a problem and now that supply has dried up, it was time to sort the problem once and for all. So now the problem is solved with these harness assembles you can convert your engine to run on the readily available REL37B Champion spark plugs. 


Available to purchase assembled or if you’re feeling confident and want to try save a few pounds you can purchase in kit form with a drawing to help with assembly.

The assembled Harness come with UK CAA release.
