HKS M-Series Super Fire Racing spark plugs are high performance
Iridium plugs designed to handle advanced levels of tuning and provide
Improved ignition performance, durability and anti-carbon build-up
M-Series Super Fire Spark Plugs Feature:
-
0.6mm Iridium Alloy Center Electrode
Iridium Alloy Center Electrode reduces voltage requirement as well as improving ignition performance and durability.
-
Outer Electrode with Platinum Chip
The Outer Electrode incorporates a square platinum chip which improves
durability, and when combined with the iridium center electrode boosts
ignition performance.
-
Short Type Outer Electrode (Anti-Vibration)
The outer electrode has been shortened and engineered with the
ideal shape to decrease weight for resistance against vibration. This
anti-vibration design improves longevity of the outer electrode.
- Thermal Edge
After long idling or various combustion conditions carbon buildup can
occur causing misfires. The Thermal Edge of the ceramic insulator will
discharge to help decrease carbon deposits.
- Spark Support Gap
Discharges will occur in the Spark Support Gap (space between the tip
of insulator and the base of the outer electrode) to help prevent
carbon buildup.
*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.
