The HKS MR lineup is equivalent to NGK No. 8 and No. 9 heat values. This new series of plugs inherits the best from the existing M series and features a Ruthenium Alloy Electrode to provide a reliable spark for all vehicles, including vehicles with increased boost or lightly tuned vehicles.
On top of an extended lifetime, use of Ruthenium alloy allows a better fuel burn, resulting in quicker throttle response, smoother idle and better cold starts.
Ruthenium Alloy Center Electrode reduces voltage requirement as well as ignition performance improvement and durability. Brass Terminal offers firm fitting to plug wire or coil-pack. Plating coating for better insulation and excellent corrosion resistance.
Outer electrode with platinum squre chip improves ignition, maximum durability, combustion speed and quality. The outer electrode has been shortened and engineered with the ideal shape to decrease weight for resistance against vibration.
- Durability is ensured by alloying the central electrode with ruthenium.
- The center electrode diameter set at 0.6mm reduces the required voltage and improves ignition performance. (Stock: 0.8mm)
- Ground electrode with platinum alloy tip improves durability and ignitability. Shortened ground electrode length contributes to electrode strength and durability.
- The ground electrode contains a copper core to suppress temperature rise of the electrode and improve durability.
Please Note: Heat range 9 spark plugs are only recommended for tuned cars.
