Overview:

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 12 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.

    Measure Carefully
    Color: Champagne, Size: 12
    Great quality, handsome style with a modern color, and fit. Just be aware if your little guy is smaller in stature the arms may be a bit long. Measure carefully.

    Great little boy blazer
    Color: Dark Blue, Size: 8, Color: Dark Blue, Size: 8
    Too adorable and good quality. My picture doesn't do it justice. A nice dark blue with a subtle pattern. Will go well with many outfits. Fits well and not too snug with a shirt or light sweater underneath.

    Long sleeves
    Color: Dark Brown, Size: 14
    Looks so good on my boy. I bought a little big (size 14 for my 11 year old) and turned the sleeves in a couple inches, which requires moving the buttons, but I think he might get a couple years wear as he is probably about to hit a height growth spurt. It doesn't look cheap - the material is thick enough to drape nicely.

    Surprising quality, excellent attention to detail, and satisfying shopping experience
    Color: Light Grey, Size: 4
    This shopping experience was fantastic. First of all, its quality definitely exceeded its price, and the texture is very good Very thoughtful, great attention to detail, absolutely standard suit!!! What I love the most about it is its fabric. It makes me feel at ease when my child wears it, and it won't be uncomfortable to wear. It's very child friendly I have no doubt about the size, its waistband is adjustable, at least for my son, it fits well
