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.

    Good value and good material. Great size and thickness. My pit loved it until I drove over it with my riding lawn mower. I will be buying another soon.

    Updated title: Not for a power chewer
    Size: Dog Rope Toy - M
    Update: I had to cut the ball off the same day I wrote this review. Two days later, the yellow rope was totally unraveled and I had to throw it away. She got maybe 3 days of play with this toy. Do not buy this toy if you have a larger dog that chews a lot. I will say our dog loved this toy the moment she started playing with it. But the toy doesn't last long with our superchewer. I was hoping to use it for some games of tug, and while we're at it get her teeth cleaned by the spikey red ball. The listing includes "large" dogs. My large dog (11 m/o Bernese puppy) had this toy broken within the first 10 minutes. The red pieces are a pretty lightweight plastic that she just broke apart completely, specifically the bone on the "handle". The ball is lasting a little longer, but she put a hole in it. We will probably need to cut the ball off as well because she'll chew it up and swallow it if we're not careful, and then she'll need (another) surgery. The positive is that she loves chewing on rope and the rope pieces seem pretty sturdy. We still play tug with the ropes, but this one I will probably just give to her as a chew toy. We found a more durable ball on a rope toy at Target for a little bit less.

    One of the two main strands of the toy are totally ripped apart and frayed before ever being used. Will fall apart very quickly, returning.

    Very good squeaker sound and well made
    Style: Hedgehog dog toys
    My spaniels are so accustomed to this very specific squeak, that they come running no matter how far they’ve run. Unfortunately it’s bulky to carry in my pockets so I wish I trained them (trained? That’s a stretch!) with a different, much smaller, squeaker but so far they’ve held up really well and Max now uses it as a small little head rest. Very cute.
