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

Good value. Not OEM
These clips don't fit perfectly for my honda civic. They also aren't as strong or durable as the OEM clips. The plastic is harder so they crack and fall out instead of giving if you're driving on bumpy roads. However, having a bunch of these clips in the back so I don't have to look up part numbers and order a bunch of different things is great. It does the trick and is way better than having your trim fall off. It's a quick and dirty fix... but hey, if you do DIY repairs and aren't going to the shop for it, it's probably what you are looking for.

Clips are awesome, tools kinda crappy
The assortment is on point with OE supplied retainers, the ones with metal especially are just like the originals offered by Honda.

Honda Panel Pop Rivets
Why did you pick this product vs others?: This product pack offered all the sizing I needed. The rivets fit perfectly in the wheel well panel. I was able to replace the window washer reservoir and replace all the rivets. The end result was a panel held in better than before I started the project.

Worth the money
Had to pull the front bumper on my 2012 honda cr-v. Had all the clips that I needed except two on each side in the fender weld. Worth the money.
