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.

Best old guy shoes. They look great and have support for feet. You don't want cheap department shoes. You will pay for that in your later years.

Comfort Meets Performance — Nike Men’s Journey Run Road Running Shoes
Size: 10.5, Color: Black/Summit White/Anthracite/Cyber
I picked up the Nike Men’s Journey Run Road Running Shoes on a whim, and they turned out to be a great surprise. From the first wear, they felt comfortable and lightweight, with cushioning that makes walking and running on pavement much easier on the feet. They don’t feel overly stiff or bulky, which I appreciate for everyday use.
What I like most is how versatile they are. I’ve worn them for short runs, gym workouts, and even casual outings, and they’ve held up well in all situations. The fit is true to size, and the upper feels breathable enough to stay comfortable throughout the day. They also have a clean, simple look that pairs well with both athletic and casual clothes.
Traction has been solid on roads and sidewalks, and I haven’t noticed any slipping, even on slightly wet surfaces. While they may not be designed for competitive racing, they’re perfect for daily training, walking, or anyone looking for a reliable, comfortable running shoe.
Overall, the Nike Journey Run shoes offer good comfort, dependable performance, and everyday style. A solid choice if you want a no-nonsense running shoe that you can wear beyond just your workouts.
