HKS M12 Long Reach High Heat Range Tuning Sparkplug With Protruding Electrode
HKS 50003-MR45HLZ
M12 Long Reach Sparkplug with protruding electrode for such vehicles as Honda Civic Type R and Suzuki Swift Sport. The 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 those with increased boost or lightly tuned vehicles. On top of its extended lifetime, the use of Ruthenium alloy allows for better fuel burn, resulting in quicker throttle response, smoother idle, and better cold starts.
Features:
- Ruthenium Alloy Center Electrode reduces voltage requirement as well as improves ignition performance and durability.
- Brass Terminal offers a firm fitting to the plug wire or coil-pack.
- Plating coating provides better insulation and excellent corrosion resistance.
- Outer electrode with platinum square chip enhances 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.
- Use of these spark plugs on a vehicle not compatible with this type may lead to serious engine damage. When replacing spark plugs, be sure to compare the shape of the new plug with the installed one. Please select an appropriate spark plug for your vehicle.
