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

An average table support.
These table legs are made of "jointed", threaded, 3/4inch steel pipes and it is imperative that they are assembled correctly and evenly; if not, the table will be wobbly and unstable. Need to ensure that the joints are fully tight. The assembly instructions are vague, so you may face some frustration during assembly if you're not too mechanically inclined. It is possible to modify the design of the legs to meet your specific needs, but you may need to purchase additional 3/4 inch piping and couplings at your local plumbing store. Good luck!

A good idea that didn't work out
The pieces are not labeled at all, the paint on the threads makes it difficult to get a good tight fit between the pieces, and the way the pipes are screwed together there are two opposing corners that always bow in an make it look like it's going to fall in. It's also really difficult to make level. I really wanted to like this because it fit EXACTLY what I wanted to use it for, but I just can't trust it long term which is why I'm giving it 2 stars.

Looks great & saves space
Color: Rustic Brown and Black, Color: Rustic Brown and Black
I couldn't be happier with the look and the space it's saving me. It came very well packaged, even with corner guards on the wood shelfs. It was very easy to assemble and attach to the end of my pantry in the kitchen. That space was just going to waste. The ladder shelf fit perfect and looks great. I love the color and texture of the wood grain, it really goes well with the black metal rail. It will be a little wobbly until you get it screwed down to the wall but after that, it's good and sturdy. The instructions were easy enough to read but I still found a couple of parts I didn't use and wondered what they were for? The parts do come numbered but only on the packaging? Not on the part itself which would have been more helpful to some extent. So just keep it all together with it's packaging and you'll have no problems. Very happy with purchase.
