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.

Perfect for Prom, the satin detail elevates the look
Size: Medium, Color: Black, Size: Medium, Color: Black
This sport jacket was a great item for prom. We had it altered and taken in a little to be more form fitting. It was lightweight enough to be comfortable and the color was a nice black with satin collar. It was a great value for the money and this is the second one I've bought. The first one was red for freshman homecoming. Fits true to size as this is a medium but we did want it a little more form-fitting.

well made

My son looked SO handsome for Prom. This suit was surprisingly well-made for the cost. After pricing tux rental, this was a no-brainer.
