"Swap the wires one at a time so you never cross two cylinders. Route them back in their original clips to keep them off the hot exhaust."
Frequently Asked Questions
Should I replace plugs with the wires?
It is good practice - fresh plugs and wires together give the cleanest ignition on the little three-cylinder.
Do these fit the firing order?
Yes, the set is cut for the Acty E07A. Move one wire at a time to keep the order correct.
How do I test my spark plug wires?
On a dark night with the engine running you may see spark arcing along cracked wires. You can also measure resistance end to end with a multimeter; an open or wildly out-of-spec wire is bad. A damp-weather misfire is a classic sign.
