Description

HKS plugs are our go-to choice for spark plugs for the 1.6L Turbo engine.

At a NGK Heat Range 9 equivalent, these plugs will ensure there is less heat when you are making more power. We highly recommend this plug when running our Tunes!

Here is a good article on Spark Plug basics by NGK.

HKS Plugs ignite faster for the best fuel efficiency and the best performance in all situations and environments. It is very important to provide safe and stable ignition for the engine to perform at maximum power. HKS Super Fire Racing plug is the best plug for extreme racing driving and also works well for normal tunes.




  • 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.

    HKS Spark Plugs

    These plugs brought life to my 2022 Forte GT 1.6LT Manual, Idles great better throttle response, to get the most out of them you need racing coils!

    10/10 would recommend

    Packaging was a bit shoddy but the khs packaging of each spark plug was good enough that it survived rough handling. pre gapped for your enjoyment :)

    A must to get for ECU tune

    I bought these with my Stage 1 High Torque spare ECU tune.

    My car stopped operating

    I purchased a set of these spark plugs for my 2017 Hyundai Elantra Sport, as I have been changing out my spark plugs since I purchased the car. I decided to try these, upon getting them and installing them with a light torque set as I always do ( 5-7 lbs) before I fully tighten them down. One of them stripped on the 4th cylinder entry hole! How great, so now I had to call a friend to come help tow the car to a shop and the shop states that my car has metal pieces in the engine and its locked up. OHHHH GREAT, so now they state that some of the material from stripped plug may have entered into the engine :/. So now my car is at a dealership, thank god for warranty but I would not trust these sparks. Just go with the generic or dealership sold plugs.
