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.

    Loooove these shoes!
    Size: 7.5 Wide, Color: Chestnut Brown Faux Leather
    I have these in several colors, and they’ve become a true staple in my wardrobe. The Amazon Essentials Women's Belice Comfortable Slip-On Ballet Flats are exactly what I look for in an everyday shoe—simple, versatile, and comfortable right out of the box. The slip-on design makes them super convenient for busy days, and they pair effortlessly with everything from jeans to dresses to work outfits. They’re lightweight but still feel supportive enough for all-day wear, and I appreciate that they don’t require a break-in period. The fit is generally true to size, and the variety of colors makes it easy to stock up and rotate depending on the outfit. Overall, these are reliable, easy-to-wear flats that offer great value for the price. Not flashy, just consistently comfortable and practical—which is exactly why I keep coming back to them.

    REALLY CUTE SHOE BUT CUT WAY TOO SMALL!
    Size: 8, Color: Black Patent
    I received the black patent leather shoes today and they are so cute! Sadly I need to return them because they are cut way too small. I normally wear a 7.5 or 8 on dress shoes so I ordered the 8. They are so tight across the top that it's uncomfortable as soon as I put them on. They are smaller than a normal size 8 dress shoe. The big toe area is extremely uncomfortable because it doesn't allow any room for it at all, so my big toe just presses against the side and end of the shoe without even walking in them. I have very narrow feet and these still are too small for me. So I am returning them and I already ordered a 8.5 W and hope that will fit much better. The patent leather is very cute and adds just enough dressy that I can wear them with slacks or my Capri jeans. I like the slip on and the cushion foot bed because it feels soft.
