BRISK SILVER RACING SPARK PLUGSMaterialsSilver is the best thermal (heat) conductor of all metalsAllows for a wide spark plug heat rangeExcellent heat dissipation under max. powerExcellent resistance to fouling under light load operationSilver is the best electrical conductor of all metalsMost free electronsBest power deliveryMost powerfull sparkConstruction1.5 mm Silver Fine Wire Center ElectrodeLow ignition voltage requirements (easier for spark to jump over)Reduces stress and wear on your coil and other ignition componentsFires properly even if partially fouled, where standard plugs will failExcellent for:Standard and High compression enginesForced induction applicationsNitrous applicationsMethanol/ethanol injectionLPGAny hard to ignite type of fuel applicationsHigh RPM race engines where is a short time for the ignition coil saturationBeneficial even for old vehicles with a weak ignition systems and/or excessive oil consumptionTapered or Cut-Back Ground ElectrodeProvides sharp edges for easy spark dischargeExcellent spark exposure to the air/fuel mixtureFaster flame front propagation in the initial stages of ignition due to reduced ground electrode obstructionHigh dielectric strengthFine wire center electrode (not just tip) increases the thickness of insulator between the center electrode and the spark plug shell for higher mechanical and dielectric strength.-Honda City GM6 2013-2018-Honda Jazz GK 2013-2018-Proton Inspira -Mitsubishi Lancerdo message us and tell us your car model before placing order
