Overview:

The MSD 8.5mm Super Conductor is the ultimate performance wire! Its extremely low-resistance combined with the ability to suppress Electro Magnetic Interference is a combination that defies the common laws of physics. Less resistance means more energy is going to make it to the spark plug to ignite the air/fuel mixture. The Super Conductor uses a copper alloy conductor resulting in less than 50 ohms per foot of wire! This ensures that the most energy possible makes it to the spark plug. By helically winding the conductor around a special core, we are able to produce a highly effective choke to keep the EMI inside the wire and away from other electronics. This combination is encased in a heavy duty sleeve that will withstand abrasion and high temperatures. Cap off each end with our Dual Crimp Terminals and you have the best wire available. Equipped with high temp silicone-fiberglass sleeving for the harshest race conditions that protects wires up to 1,000 °F.

    My perfect summer blanket
    Color: Grey, Size: King (108" x 90")
    I had 0 expectations for this blanket and I was pleasantly surprised. This blanket is very lightweight, much like the novelty throw blankets you find in the kids section. It's very soft, compared to chinchilla fur. Incredibly soft and it didn't make me hot. Nor did it keep me cool. For me, it's the perfect blanket for summer weather. So far, the quality seems really nice and it fits my needs as a king size.

    Soft, lightweight, warm and long blanket
    Color: 04 - Cream, Size: Throw XL (50" X 70")
    Very nice blanket. It's soft and long enough to cover you when laying on the sofa and warm. It also washes and dries well on warm water normal dry. I highly recommend this blanket

    Bought in multiple colors! Fantastic material
    Size: X-Large, Color: Light Green, Size: X-Large, Color: Light Green
    I ordered this button-up for an upcoming beach vacation, and I’m honestly so impressed with the quality and feel of it. Right out of the package, the material felt soft, breathable, and exactly what you want when you know you’ll be spending long hours in the sun and heat. It’s incredibly lightweight without feeling cheap or flimsy, which was one of my biggest concerns when ordering. What I really love is how well it helps keep you cool. The fabric allows for great airflow, so you don’t feel like you’re overheating or sweating through it like you might with heavier shirts. Even just trying it on, I could tell it’s going to be perfect for hot, humid weather. The fit is also spot-on—not too tight, not too baggy—giving it a clean, relaxed look that works great for both casual outings and slightly nicer dinners by the beach. Overall, this shirt checks all the boxes: comfortable, breathable, stylish, and ideal for vacation wear. Already grabbing a few more colors

    Slim but comfortable sizing looks upscale, wrinkle free from the dryer
    Size: Medium, Color: Denim Blue
    This is a very nice upscale looking shirt. It has great styling that is not over-sized. My husband normally wears a medium or large depending on the cut/style. He got a medium in this size and it is a perfect, comfortable fit. It arrived with some creases in the material from being folded in the packaging but it came out beautifully from the dryer. I'm happy he has a casual but nice shirt to wear when he takes me out to dinner!

    Nice and comfy, light duty and feel great.
    Size: X-Large, Color: Light Green
    What they may lack in "durability" i.e. very light and thin = not going to last all that long, they make up for in fit [yes even for wide shoulders], comfort and style. If you want them to last, suggest a gentle cycle and just take ot easy on them. They are light, thin, and airy. Nice summer shirt.
