These are 8MM Spark Plug Wires. They are replacements for discontinued MSD 3119 wires. The stainless steel conductor offers lower resistance for maximum voltage carrying capabilities and will not affect other ignition controls or on-board electronics. The outer sleeve is constructed of a tough high temperature silicone jacket. An excellent upgrade for OEM plug wires.

Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference! In a single 8 inch length of Super Conductor Wire there is only 40 - 50 ohms of resistance! That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to it's great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference (EMI) "choke". This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. The MSD's 8.5mm spark plug terminals feature Dual Crimp terminals. As the name implies, the terminals feature two crimps; one for the sleeve of the wire and another separate crimp to grasp the conductor.

Whichever type of boater you are, know that when your Mercruiser spark plugs and wires are in need of replacement that you’ll find just what you need, and receive it just as quickly. Wholesale stocks a wide range of wiring harnesses by Sierra a name boaters trust. If you’re not certain exactly what part you’ll need, you have two options.
Need Help Selecting the Right Mercruiser Spark Plugs/Wires?
There are two schools of thought here. Those boaters who push the envelope and replace their Mercruiser sparks and wiring only when one or both fail, and those who watch their engine hours and replace each according to their manufacturer’s recommendations.
Over time, salt spray, humidity, and UV rays take their toll on many boat systems, even those that are not readily visible. That is why it is so important to routinely check your Mercruiser spark plugs , wires, and wiring harness for signs that its service life is over. If your plugs are pitted and your engine performance has diminished, their replacement is a no-brainer. With wiring it is a bit harder to tell.
Be sure to use our convenient parts selector to find just the right Mercruiser spark plugs and wires for your engine. If you’d prefer, speak with one of our knowledgeable representatives. We’re here to serve you Monday through Friday from 9:00 AM until 6:00 PM EST at (877) 388-2628. For even greater savings, don’t forget to ask us about our Captain’s Club Rewards Program .

Some boaters believe that marine spark plug wires and those manufactured for land vehicles are interchangeable. That is not the case. Many boating forums offer discussions regarding this topic, citing the difference in wire thickness, the need for a waterproof wire casing, improved ignition, and other differences proving that marine spark plug wires require different characteristics than automotive plug wires. Wholesale Marine agrees, however, a key difference between the two is the length of the wire itself. Marine wire sets are longer as these must be routed around the marine exhaust manifold. An additional major difference between these different spark plug wire sets is that the marine distributors have different cap ends than those in automotive sets. here
