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
Thread Size: 14mm × 19mm
Wrench Size: 20.8mm

bought twice to make custom UPS setup battery leads, not disappointed
Color: Black, Size: 25-Feet
bought this item(25ft 2awg) twice, the first time I did was to create some quick connect cables between my batteries and my distribution block to my 4kw invertor(24v 165a peak calculated load) I may have oversized due to knowing that the bigger you go the less you stress components and loose power to voltage drop these cables are a nice high-grade rubber jacket and the 30awg strands are ideal for maximum flexibility while remaining fairly easy to terminate this cable also includes a backer paper wrap that allows for easy stripping(of the rubber) without too much strand loss damage(from cutting too close to the core) overall, would buy again, like I did, if I need larger runs(say for feeding an RV solar AC distribution panel) I would buy this brand again, in the 100ft range or so THHN is not ideal for flex connections(strands are way too stiff) but a couple runs of welding cable like this inside something like "smurf tube" would be a perfect high-power temporary connection system, or just a way to isolate a large battery stack used for a solar setup in fact I may do that someday, set up a pallet of LiFePO4 batteries with a large quick connect, and just recharge the massive array(s) at a secondary location where solar is more ideal(or other renewables)

Custom wires for winch solenoid pack relocation.
Color: Black, Size: 25-Feet
Wire is nice. Flexible. Seems good. However the inner liner is not moisture blocking as I assumed from the pictures, it's paper.. still seems like a good price per foot.
