HKS Superfire Spark Plug Toyota Yaris GR 3cyl Turbo


HKS Super Fire Racing Spark Plugs - Yaris GR


Spark Plug replacement or upgrade. Ideal for minor bolt on modifcations and or tuned cars.

Recommended for add on power chips that increase boost to keep the spark plugs cleaner and perform consistently. Pre gapped ready to install.


Part: M45HL

Qty: Sold as a pack of x3. 


  • 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.
  • Vehicle Fitment
