Excellent set of spark plug wires!
Replaced old set of spark plug wires on a 140hp Mercruiser inboard motor in my mudboat. The old wires were very worn from rubbing together etc. Boat is run in brackish water so I was pleased with the stainless ends to go on plugs and distributor. Very High Quality. Motor runs great now.

Good quality. Lengths just good enough for 3.0
Switching out my old OEM wires for this set definitely improved engine performance, especially with start up. The lengths are not exact to the OEM but at least they're a little bit too long and not too short - a very minor point.
