Overview:
ACCEL HP Spark Plugs are made with a Copper core which is a better conductor than Platinum and Iridium. They deliver a stronger spark especially in high performance applications where high combustion pressures are present. Copper is much better at dissipating heat than other materials which lessens the chance of a misfire. ACCEL HP Spark Plugs are gapable allowing you to open the gap exposing a larger flame kernel or close it if needed for high boost applications. All ACCEL HP Spark Plugs have machine rolled threads allowing for a more precise thread engagement and torque retention.
Features:
- One Piece Design - Won't break off in head during removal like two piece designs
- The Copper core is a better conductor than Iridium or Platinum plugs
- Copper dissipates heat much better than other materials
- "C" - Cut Design un-shrouds the spark kernel for a better burn
- Unlike Iridium or Platinum plugs, the ACCEL HP plugs are gapable
- Machine rolled threads for precise thread engagement
- One step colder than stock

Fun Toy for Active Dogs
My dog enjoyed playing with this toy and stayed entertained for a long time. It moves well and keeps pets curious and active. Easy to use and good quality for the price.

Durable Interactive Dog Toy with Bluetooth Sounds – Perfect for Dogs Who Love Cat-Style Toys
This interactive dog toy is surprisingly durable and very engaging, especially for dogs that love cat-style toys. My dog is obsessed with cat toys and also always wants to destroy something, so this toy is a perfect match. The Bluetooth sound feature makes it even more fun and interactive.
Pros
• Very durable main body made of hard plastic; my dog hasn’t been able to destroy it
• Great for dogs that like “mouser-style” toys
• Bluetooth feature lets you play animal sounds or music (I use Spotify dog playlists)
• Three different modes and very easy to switch
• Interactive and mentally stimulating
• Comes with two replaceable ropes, which I’m really happy about
Cons
• The ropes don’t last long for strong chewers
• The top part where the rope is attached can be chewed
Overall
Honestly, if there weren’t any parts my dog could destroy, he probably wouldn’t find the toy interesting. That’s why I’m actually happy it comes with two ropes that I can attach and replace. The ropes are inexpensive and easy to swap out, so it’s not really a downside for us. Overall, this is a fun and clever toy that keeps my dog entertained. 🐶

Great for 2 Days…see comments
So it’s great toy and had our dog entertained immediately. However probably won’t last very long with medium to large dogs that gets obsessed with killing every toy you give them. Our Pitt mix loved this until she ended it by chewing through the heavy plastic ring that keeps the ropes connected. Without the noted ropes attached, the toy cannot move around. Basically ending the fun. Would be great to start a puppy or smaller dog on. It has multiple modes and is noise and proximity activated. Our dog was obsessed but sadly it was no match for her. 3 stars only because it didn’t last more than two days with our dog.

Good but not tough
My dog loved it but he figured out how to open it pretty quickly. I think I’m doomed to never find an interactive dog toy that can survive my golden

Obsessed, crappy rope
My pitbull mix is obsessed! I was worried he might break it, but he has used it everyday for the past week and we've had no issues. The reason I docked a star is because the rope it comes with lasts minutes. I'm still trying to figure out a good solution of what to tie onto the top. Regardless, he loves it without anything on it, but he chews on the connector piece so I'm worried he will break it if I let him go.
