HKS M-series Super Fire Racing Spark Plugs which feature 0.6mm Iridium, and ignitionability, durability, and anti-insulation are all reinforced. The heat range is one level higher than the original SUZUKI ones. These products are excellent spark plugs for souped-up engines that have been arranged with air-fuel ratio adjustment, increased boost pressure, ECU remapping, or replaced with upgraded turbochargers. Made in Japan.
- 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 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 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.
- 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 improve durability which allows for use under hard combustion conditions like continuous high load during circuit driving or aggressive tuning.
- Decreased Carbon Deposits
Thermal edge and spark support gap help prevent carbon buildup for better ignition under various combustion conditions
Comes in a set of three spark plugs.
* Heat range is #40. Equivalent to NGK spark plug heat range #8.
* Improper combustion conditions and wrong heat range selection may cause damage to the spark plug.
* Some products in the photos are spark plugs for other vehicles.

Stock: We have a lot of products in stock, but please note some products we list are the manufacturer's stock. Also, some others are on backorder, made-to-order, or pre-order-sale, and the orders may take several weeks or more to ship.
Shipping Cost: Our shipping cost calculation system is imperfect, and the shipping quotes in your cart are estimates. There may be an additional shipping cost in some rare cases. In certain areas, shipping has been temporarily suspended, or delivery to certain areas might be difficult.
Compatibility: Our products are designed for RHD (right-hand drive) and JDM (Japan Domestic Market). We hope that most of our products will fit international models and LHD (left-hand drive) as well, but we have not tested the compatibility of some products. Please research for yourself and ensure that the part you are purchasing is compatible with your vehicle prior to ordering.
Tax: Import duties, taxes, and charges are not included in the item price or shipping charges. These charges are the buyer's responsibility. Please check with your country's customs office to determine what these additional costs will be prior to buying.
Design: The colors of the products in the photos may look different from the actual products depending on the condition of the photos and the type of displays. The specifications and design of the logo, etc. of the listed products may be subject to change for improvement.
