Brand : HKS
Product: M-Series Spark Plugs Platinum & Iridium 4-Cylinder
SPECIFICATIONS
- 0.6mm Iridium Alloy Center Electrode:
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. The Outer Electrode features a shortened tip design and tapered shape while maintaining the necessary space for proper ignition.
- 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.
PERFORMANCE AND EFFICIENCY
- improved Ignition Performance:
Decreased voltage requirement strengthens ignition performance under harsh conditions like lean mixture or high boost pressure.
- Improved Durability:
New material and design improves durability, which allows for use under hard combustion conditions like continuous high load during circuit driving or aggressive tuning.
* Improper combustion condition and wrong heat range selection might cause damage to sparkplug.
- Decreased Carbon Deposits:
Thermal Edge and Spark Support Gap help prevent carbon buildup for better ignition under various combustion conditions.
