🔌 Premium MagForce Marine Spark Plug Wire Set for Mercruiser Sterndrive and OMC Engines - Sierra International 18-8810-1 (18-6089) Review

High quality wiring harness for the 4.3 Mercruiser engine. These wires are actually blue/grey, not black, and appear to be as good if not better than the Mercruiser OEM wires that came on my 2001 4.3LH. The cables were the perfect length and easy to install. Got the boot up and running within hours of installing it and it worked great.

The product arrived well packaged and looks like a good plug-in cable. I cheated on my part numbers and got them for 3.8OMC with spark dots. They will not fit the Punkt screw cap as they are specifically made for electronic ignition. Just wanted to note for those working on their old boats. 1985 Seaswirl Spitfire with 3.8OMC

Used on my 92 Cobia with 4.3 liter Mercrusier engine. Direct exchange and no problems. Came with a good amount of dielectric grease in the connector heads.

Replaced on my Mercruzer 4.3 leads with Thunderbolt Ignition, perfect fit, excellent quality, much better quality than the originals, highly recommend Plug Wire Set

I replaced my original wires (from 1988) with these along with spark plugs, cap, rotor, coil and sensor and now my engine runs much better. They are the same length as the originals but are thicker (more insulation) for less sparking. they fit great.

High quality spark plug wire set for 4.3L V6 Mercruiser. Direct mount, easy installation, no problem. The ends of the spark plug wires snapped in with enough resistance, but not so much that they were difficult to install. These wires are very good quality and much thicker than the factory wires.
