HKS Spark Plug Superfire MX40XL-MX45XL
HKS Super Fire Racing Spark Plugs - Hyundai
Hyundai 1.6Turbo and 2.0Turbo. Spark Plug replacement or upgrade. Ideal for minor bolt on modifcations and or tuned cars. Sold as a pack of x4.
- 0.6mm Iridium Alloy Center Electrode
Iridium alloy center electrode reduces voltage requirement and improves ignition performance and durability.
- Outer Electrode with Platinum Chip
The outer electrode incorporates a square platinum chip which improves durability, and combining 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 under various combustion conditions, carbon buildup can occur causing misfires. The thermal edge of the ceramic insulator discharges to help decrease carbon deposits.
- Spark Support Gap
Discharge occurs in the spark support gap (space between the tip of insulator and the base of the outer electrode) to help prevent carbon buildup.
- Increased Ignition Performance
Decreased voltage requirement strengthens ignition performance under harsh conditions like lean mixture or high boost pressure.
- Improved Durability
New material and design improve 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 may cause damage to the spark plug.
- Decreased Carbon Deposits
Thermal edge and spark support gap help prevent carbon buildup for better ignition under various combustion conditions.
