NGK iridium spark plugs currently represent the highest-quality technological solution. They feature an iridium-alloy on the middle electrode welded on in a special process using a laser. One of the world’s hardest metals, the precious metal iridium starts melting at a temperature of 2450°C and is therefore very resistant to spark erosion. By using it, the service life is doubled on average in comparison to standard nickel spark plugs.

Durable Chew Toy That Actually Holds Up to Strong Jaws
Size: Large, Color: Bundle
This is a reliable option for a heavy chewer, especially for a large breed with a strong bite. The material feels tough and well-made, and it stands up well to consistent chewing without immediately breaking down like softer toys tend to do. It also gives a bit of dental benefit by helping reduce plaque and tartar buildup during play, which is a nice bonus since brushing isn’t always realistic. The textured surface keeps it interesting enough to hold attention for a while, and it doesn’t splinter or create a mess. Overall, it’s a solid, durable chew toy that works well for strong chewers who tend to destroy most standard toys quickly.

Love it, nice for tough chewers, split in half during play
Size: X-Large, Color: Textured Ring, Size: X-Large, Color: Textured Ring
LOVE THIS PRODUCT, would’ve gotten 5 stars but i threw it for my dog and it split in half on contact with the floor. It had lasted us well over 5 months, it’s not his favorite toy but he’ll pick it sometimes, i wouldn’t say it’s unsafe in half just don’t give the smaller parts!
