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.

    Maybe not for super aggressive chewers
    Color: A Violet, Size: For Larege Dogs, Color: A Violet, Size: For Larege Dogs
    I had high hopes for this toy, I was so excited about it. I have aggressive chewers, two Malinois/Dutch Shepard mixes and a Pit. The Shepard's chewed pieces off of it in literally 5 minutes. At the ends there is a small lip and that's where they started chewing pieces off. I had ordered a second one before I gave them this one (early Christmas present) because when I received it I noticed it felt very sturdy and durable. They do like it so since they already chewed this one I'm going to see if I can shave that lip off and maybe they won't get anymore pieces off. That'll decide if I return the one that arrives tomorrow. Maybe not good for super aggressive chewers. It's very thick and seems well made. Might just be better for other dogs.

    Fantastic for rough chewing
    Color: Bule 0, Size: For Larege Dogs
    Our big boy is rough with his toys and always seems to disintegrate his toys in seconds. I had seen this with hoping this will be the toy he doesn’t destroy. On day 2 now with the toy and he’s obsessed, even feel asleep with the toy in his mouth and still in one piece. Highly recommended for tough chewers.

    Good but not for my dog
    Color: A Red, Size: For Larege Dogs
    Dog loves it but already falling apart. Can't seem to find a truly safe dog toy that won't come apart with my aggressive chewer. Had to toss it before pieces got ingested. But great toy in the begining. Just not safe for pit/staff type dog that destroy and chew.

    Withstands big dog
    Color: Green Cactus
    As a dog mom to two active pups, I’ve gone through a LOT of chew toys over the years and honestly, many of them just didn’t hold up. Some cracked, broke apart quickly, or became rough after only a short time of chewing. That’s why I was genuinely impressed with the MewaJump chew toy. Both of my dogs immediately loved it, and what stood out most to me was how durable it’s been compared to other toys we’ve tried. It’s held up really well with aggressive chewing while still seeming safe and comfortable for them to use. I also love that it keeps them entertained and engaged longer without constantly worrying about pieces breaking off. Definitely one of the better dog toys we’ve added to our home lately and Molly and Piper would agree.

    Not recommended for strong chewers.
    Color: Green Cactus
    There was nothing wrong with this. But my dog is an absolute destroyer. She makes it her personal mission to annihilate any toy I buy. This did not last 30 minutes. Very cute and good for normal dogs that like to actually have toys to play with. Do not recommend for strong jaw destroyers.
