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 # 10

Easy to install

Super easy to install. I use different wall anchors. The anchors like all anchors that come with shelves are not great. The shelves look very clean on the wall.

This product exceeded my expectations. The installation process was incredibly straightforward—even for someone with little to no experience—and the instructions were clear and easy to follow. Once installed, it feels very sturdy and secure, with no wobbling or shifting at all. You can tell it’s well-designed and made with quality materials. I also appreciated how quickly I was able to set everything up without needing any extra tools or help. Overall, it’s a reliable, user-friendly product that I would absolutely recommend to anyone looking for something dependable and easy to install. Drill is required though.

Don't buy
Size: 23.6 Inch, Color: White
The shelf is very flimsy and not sturdy at all. It feels unstable and poorly made. Definitely not worth the money, I wouldn’t recommend wasting your time or money on this product.

Fabulous!
Size: 65.6ft, Size: 65.6ft
I have wanted some strip lights for soo long! I absolutely love these! Great quality! The adhesive is very strong and keeps the lights tight against the wall. Even with bumpy paint there was no issue with it sticking. The colors are fabulous, so many to choose from. Set up is very easy. Pull off the sticky tape and press where you want the lights to go. I have had no trouble with Bluetooth connecting. I run the lights through the app and it connects easily and quickly. There is such a variety of light themes to play with and set moods. This stip can be cut. I made sure to do it right down the middle of the copper lines. I recommend turning the lights off, making the cut, and then turning the lights back on again. What is cut off will not work. I had a bit extra that I cut off and the two ends overlap a little, but it's hardly noticeable if you stare real hard. These lights are so awesome! I highly recommend. Also it is so great to be able to turn up and down the brightness!
