Most auto ignition wires are far too long for the A-4. Went that route and had lots of excess wire all over the top of the engine...even using the shortest wires i could find.

Ordered a set from Moyer Marine and they fit perfectly...no excess.

I even tried to convince Magnecor (makers of *the best* spark plug wires) to make some up, but they didn't think there was enough of a market. So unless you want to make some up yourself, go with Moyer.

Cheers
