□iruthenium Alloy Center Electrode reduces voltage requirement as well as ignition performance
improvement and durability.
□Brass Terminal offers film fitting to plug wire or coil-pack
□Plating coating keeps insulation and excellent corrosion resistance
□Outer electrode with platinum square chip improves ignition, maximum durability and combustion
□The outer electrode has been shortened and engineered with the ideal shape to decrease weight for
resistance against vibration.
M12 Long Reach Spark plug with protruding electrode for such vehicles as Honda Civic Type
R.The lineup is equivalent NGK No. 9 heat values, see details.
New series of plugs inherits the best from existing M series and features Ruthenium Electrode
to provide a reliable spark for vehicles with increased boost or lightly tuned vehicles.
By changing the center electrode from iridium to ruthenium, it has been possible to increase
the ignition and durability more than ever.
Ruthenium technology is highly abrasion resistant to maximize durability and performance to
Provides more complete fuel burn than other precious metal spark plugs, resulting in quicker
throttle response, smoother idle and better cold starts.
Use of this spark plugs on a vehicle not compatible with protruding electrorde spark plugs
may lead to serious engine damage. When replacing spark plugs, be sure to compare the shape
of a new plug with installed and select an appropriate spark plug.
