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.

It doesn’t change the flavor
Size: 300 Count (Pack of 1), Color: Brown
Great price great value and the quality is good. You can use them in a microwave no matter how you use them. They’re durable. They don’t break down and the flavor stays the normal. It doesn’t take the flavor away.

Great choice for events and you want an eco friendly option. Big and sturdy, no leaks. We used them for a 50th birthday party with a hot food buffet.

Thick plates
Size: 500 Count (Pack of 1), Color: Brown
I’ve been trying to find thick paper plates that I purchased on Amazon years ago.this is the closest I’ve found, but still not as thick. They hold up well with the ability to put a lot of food on the plate. We don’t put much wet food on it, but I think it would do well.

Great plates, but a little expensive
Size: 125 Count (Pack of 1), Color: White
These plates are easy to use for just about any meal. They are strong and durable, and they come in various sizes to fit your needs. They’re sturdy and hold plenty of food, without getting soggy or sagging. Their sturdy compostable concept is fabulous, but it seems that it results in the item costing a bit more than I’d expect to spend regularly.

Great plate, great value
Size: 500 Count (Pack of 1), Color: Brown
I have been purchasing these plates for over a year and a half to two years and they’re quite excellent. They are very durable and hold up exceptionally well. A great value for the dollar.
