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.

    Orange looking, but large capacity
    Size: One Size, Color: Brown
    I ended up returning this product, it looks more orange in color than what is pictured. Also, it doesn't smell like leather. On a positive note, it was inexpensive and did have a large organization capacity.

    Best wallet on the market.
    Size: One Size, Color: Nubuck Black, Size: One Size, Color: Nubuck Black
    This is the only wallet I buy now. Over and over. I like simple wallets. No bifold. Trifolds hurt your back. Hard case are a mess that rub your credit card mag strips off from friction. I found this a few years back and have bought 3. I am a stone worker so mine get worn from the dust and grit in my pockets faster than normal wear and I need to swap them out every couple of years. I like the simplicity and the fact that the pockets are stitched the same depth so your cards stack like varying length stair-style tabs rather than all the same depth. Wallet is RDIF protection lined. I can put like 15 cards in this wallet and it’s still thinner than a bifold holding 5. I love it. I mean it. I haven’t found a better wallet than this one. They are very well-built. Picture shows wallet with 19 cards + 40 dollars. 3/4 of an inch thick.

    Good product although the leather is a bit stiff. Hopefully it will soften up over time. Fair price, fast shipping…
