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 # 7

how good the product is
Item Package Quantity: 4, Size: Standard
These pillows are soft, fluffy, and surprisingly supportive for the price. They’re comfortable no matter how you sleep — whether on your side, back, or stomach — and they maintain their shape well overnight without going flat. The fabric cover feels smooth and breathable, keeping things cool through the night. After a few days of fluffing and use, they settle nicely into a perfect medium firmness. They also wash and dry easily without clumping. Overall, a great‑value pillow set that offers comfort, versatility, and quality — ideal if you need an affordable yet cozy bedding refresh.

Firm and comfortable
Item Package Quantity: 2, Size: Standard
These pillows are well made. Firm, yet comfortable. I am pretty rough with my pillows. I toss and turn frequently. After one year, they are still holding up.

Quite good. I am actually surprised. Too small for queensize
Item Package Quantity: 2, Size: Queen
These pillows are actually good. After reading a ton of reviews I pulled the trigger on these. I was 100% sure I was going to receive bad quality pillows (too flat or too thick). They do take 24-48 hours to firmen up. Let's see if they flatten out in a few weeks or if they hold up. My wife said the pillow was too thick and it raised her head too much. I don't agree, I sleep perfect on these, no neck pain in the morning. Update 04/24 These are actually quite small to be considered queen pillows. They have become firm over the last few days.

These Euro size pillow inserts are fantastic! They’re soft, full, fluffy, and hold their shape very well. The firmness is perfect — supportive without feeling too hard. They filled my pillow covers beautifully and made the bed look much more luxurious. Great quality for the price and very comfortable for lounging or sleeping. Very happy with this purchase!
