HKS Super Fire Racing M45XL Spark Plug

Important Note: All HKS Spark Plugs Are Sold Individually - Please Purchase The Amount Needed For Your Car.

XL Type

Thread Size: 12×26.5mm

Wrench Size: 16mm

Heat Range: NGK #9

Ultimate spark plug "M".

Ignitionability, durability, anti-insulation all reinforced. HKS has made the best plug for both tuning engines and stock engines.

Features

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. 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

  • 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 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 the spark plug.
  • Decreased Carbon Deposits
    Thermal Edge and Spark Support Gap help prevent carbon buildup for better ignition under various combustion conditions.

  Special Design RE-type for Rotary Engines

  Rotary engines reciprocating design have a different mechanism and combustion condition. RE-type spark plugs are specially designed to meet the different requirement for rotary engines. The straight shape platinum outer electrode enables reliable ignition performance.
