Overview:

The traditional ACCEL combination of yellow wire and red spark plug boots has been added to these SuperStock Spiral Core 5000 Series wire sets, which feature color-matched wire and spark plug boots in blue, black, and red. With only 500 ohms/ft. of resistance, more ignition energy can reach the spark plug, producing a longer-lasting, hotter spark flame kernel. The results is higher performance through improved efficiency, quicker throttle response, and reduced emissions. This 8mm wire's double silicone construction is rated to 550 degrees F. The high-gloss wire jacket resists moisture, chemicals, and heat extremes for longer life and great looks. The fiberglass braid adds greater pull strength and terminal retention, while the stainless steel spark plug terminals provide excellent long life, electrical conductivity, and corrosion resistance. Both universal and custom-fit applications are available for early and late model cars and trucks.

Have bought a few of these over the last handful of years
Color: Red
Best toy outside of Ghonuts for heavy chewers. Even outlasts the most durable Kongs. I'd say we get about four months before our dog starts really making a dent in it and the size of the pieces he pulls off start to become larger and I should probably replace it after about six months. It's cheap enough that replacing it that often is fine. *Important note* using squishy toys for heavy chewers is really important. They can break their teeth on hard toys like Nyla bones and things like antlers can break and cut them and damage their digestive system if they swallow the shards. It sucks because my dog loved Nyla bones and would chew off an inch a day, but I couldn't risk his teeth like that.

Finally - a tug toy my dog hasn’t destroyed!
Color: Red
This completely exceeded my expectations! My dog is roughly a year old, about 110-115lbs and a TOUGH chewer. He loved tugs toys but none of them last more than 10 minutes with him. I decided to try this because of the other reviews and price but wasn’t expecting it to last long. He’s had it almost a week and it’s still completely intact. It’s definitely heavy so it might not be best for smaller dogs but if you have a big dog/heavy chewer definitely give this a shot!

Indestructible so far
Color: Red, Color: Red
My toy destroyer has had this for almost two months now and it hasn’t taken any damage. It is big and heavy and solid. It became one of his favorites immediately and goes in and out of the house and even to bed with him. Now if only we could find a stuffy that he can’t destroy.

MY DOG'S AREN'T INTERESTED ...
Color: Red
This is a large, heavy, hard rubber toy, so is of high quality. However, it is SO heavy that neither my 60-lb. female Boxer nor my 80-lb. male Bully will 'play' with it at all. They don't even chew on it. So, although it would probably be pretty indestructible, I have no way to verify that, since neither of my dogs show any interest at all. I've tried encouraging them, by holding on one end of it and encouraging them to grab the other end, but even that didn't work. Perhaps a much larger 'giant' breed dog would enjoy it.

Tough chewer for sure
My dog destroys toys. These are amazing, she chewys on them tell she's a slobbery mess. And they are holding strong. Glad a found these!
