    MSD's Universal Spark Plug Wire Sets are available in your choice of black or red wire for a variety of applications and include a spark plug terminal and installed boot with one open end. The set also includes distributor cap boots and terminals so the wire can cut to a specified length and installed with the supplied mini-stripper-crimper.

    MSD's Replacement Spark Plug Wires and Coil Wires are made with the same Super Conductor wire as their universal and pre-made sets, just longer than normal for custom tailoring when you need that extra length.

    Features:
  • Only 40-50 ohms resistance per foot of wire (lowest of any helically-wound wire)
  • MSD Ignition Copper alloy conductors result in less spark energy loss so more reaches spark plugs
  • Over 40 feet of conductor per foot of wire
  • Conductors are wrapped around ferro-magnetic center cores, which effectively suppresses electro magnetic interference
  • Outer sleeves consist of silicone and synthetic material for a strong resistance to heat, abrasion, and tearing.

    Rated 5 out of 5 by from Great Products and Great Service! I purchased this item a couple of weeks ago. I think MSD has the best ignition products in the market. They are extremely high quality and they last. Additionally, JEGS! is the place to purchase products for your project or track vehicle. Their customer service is world class. If I need parts or technical expertise, I go to Jegs! You can try the others, but I don't think you beat Jegs!

    Rated 5 out of 5 by from No Problem I really liked the kit. Easy to understand, and Youtube video made this really simple to do. I would recommended this kit if your having to make custom wires to length and fit. I bought extra boots to help around the headers. The Tech. Help dude ordered the right ones I needed if you can't find them on your own.

    Rated 5 out of 5 by from Great Plug Wires! First set of MSD wires I've owned, but won't be the last. Put them on my daily driver Chevy C10 P/U here recently. I haven't been able to really put them through a test, but these things are tough. Very tight fitting, look exceptionally well. Heck they even smell good!
