M-Series Super Fire Spark Plugs

HKS M-Series spark plugs are high performance Iridium plugs designed to provide improved ignition performance, durability and anti-carbon build-up.

  • 0.6mm Iridium Alloy Center Electrode
  • Outer Electrode with Platinum Chip
  • Short Type Outer Electrode (Anti-Vibration)
  • Thermal Edge
  • Spark Support Gap

M Series is recommended for reliable ignition, durability and anti-carbon buildup under high load.

The Iridium alloy is used because of its durability and reliability.  On an average plug, a narrow core typically shortens life span of plug but with the intense durability of iridium there is no sacrifice in any longevity.  With a high melting point of 2454 degrees C, opposed to the 1769 degrees C of white gold, the electrode can tolerate the high levels of compression and minor knocking without any deterioration. A nickel coating on the housing also prevents the spark plug from premature deterioration.  The Iridium plugs are available for multiple applications and offered in "colder" heat ranges of 7 and up and specifically for rotary, heat ranges of 9 and up are offered.

Heat Range: NGK # 8
Thread Size: 14mm × 26.5mm

Held Up Better Than Most for My Aggressive Chewer
Color: purple, Color: purple
I have to give the Fuufome Dog Chew Toy for Aggressive Chewers a solid 3 out of 5 stars. I have a very high-energy Lab mix named Boone who is an extremely aggressive chewer. Finding toys that last in our house is nearly impossible. This is actually his second toy like this - the first one is currently in my yard in three different pieces. While I don’t believe this toy was advertised as indestructible, I still hoped it would fully survive Boone’s chewing. Some parts have held up well, which is more than I can say for many other toys we’ve tried. However, he was still able to do some noticeable damage to the rubber portion after consistent use. To be fair, it did last longer than most toys we’ve purchased, which says a lot considering how tough Boone is on his things. For moderate chewers, I think this would hold up quite well. For truly aggressive chewers like mine, it’s tougher than average but still may show wear over time.

Best toy for heavy chewers
Color: Green
My dog is an aggressive chewer and I have trouble finding toys that last longer than 5 minutes before being so destroyed it is no longer safe to let him keep it. He loves this toy and naws on it for hours daily. Yes, it has multiple chew marks, but it is still intact completely. No little pieces have been chewed off. I highly recommend this toy for any dog especially those who destroy every toy in seconds like mine does.

NOT Indestructible and a Nylon Product (NOT A CHEW TOY)
Color: Green, Color: Green
I gave this dog toy 2-stars based on my dog toy rating system (DTRS) for “Bruce” the Green Alligator! Unfortunately, I didn’t notice in the fine print of the product description on the website that this toy consisted of Nylon. If I noticed that description, I would’ve never purchased this product. Please do your own research on Nylon wrt teeth. I wasn’t impressed with the toy construction out of the box. The nylon head and tail sandwich the rubber body with soft rubber spines on Bruce’s back for easy gripping. This is not an “Indestructible” dog toy. Safety (1-rating): 1. I was always concerned about my dog’s teeth possibly cracking while he was chewing on Bruce’s Nylon ends. Thankfully, his teeth were fine throughout the use of this toy. 2. The Nylon came off in small pieces after a few hours and continued for the life of the toy; see picture. I never intended for my dog to swallow pieces of Nylon. 3. Bruce’s rubber rear end is where most of the damage occurred, as my dog was tearing off pieces of rubber and spines, which he thankfully passed through his system over a period of 2-3 days after I threw Bruce away; see picture. 4. The chewed-up Nylon ends were very hard, rough, sharp and pointy. There were occasions where I noticed my dog’s gums were bleeding as a result of chewing this toy. 5. Bruce is big enough not to swallow in its entirety, which is why I’m giving this a 1-rating for safety. 6. This is a molded product and not a plush product. Durability (2-rating): 1. It took my dog 1 to 2-weeks to get the toy in the shape that is shown on the posted photos. 2. The Nylon was immediately being scratched and scraped apart on day-1. Then I noticed pieces of Nylon coming off of Bruce after 3-4 days. 3. The rubber was immediately being punctured with small divots around the body on day-1. I noticed over the next couple of days that my dog was focusing on the rear end and trying to pull the rubber off the Nylon tail. 4. The rubber started coming off more quickly after 1-week, until I removed it all together. Squeaker (N/A): 1. Bruce has no squeaker. Fatality (2-rating): 1. Bruce had a longer life than most of my dog’s toys, but then again, I expected this to last much longer as the seller claims it is “Indestructible”, which it is not. 2. I tried filing off some of Bruce’s chewed up Nylon ends to smooth them out for more chew time, but came to my senses and just threw him away for safety concerns only. In conclusion, “Bruce” the Green Alligator should not be given as a chew toy, but more as a fetch toy, unless you want your dog to digest the Nylon and rubber materials.

Heavy duty, excellent quality
Size: Small, Color: Textured Ring, Size: Small, Color: Textured Ring
I trust the Nylabone brand and would not buy a cheap substitute to save a few bucks. This ring is heavy duty. I got it for our 9-week-old puppy and it keeps her interested and entertained with all the little nubs. She uses it more as a toy than something to chew on, tossing it around and mouthing it. It's very hard so I'm not worried about her being able to chew off any little pieces at this point. This satisfies her for now and helps to keep her busy and reigns in some of her puppy energy. Recommend!
