BRISK RACING IRIDIUM spark plug "Power Focus" – spark is exactly in the focal point of the reflector that helps direct air fuel mixture during the compression stroke to the center electrode and consequently

without requiring a specialized spark plug gapping tool

where standard plugs will fail - Excellent for: o Standard and High compression engines o Forced induction applications o Nitrous applications o Methanol/ethanol injection o LPG o Any hard to ignite type of fuel applications o High RPM race engines where is a short time for the ignition coil saturation o Beneficial even for old vehicles with a weak ignition systems and/or excessive oil consumption Tapered or Cut-Back Ground Electrode - Provides sharp edges for easy spark discharge - Excellent spark exposure to the air/fuel mixture - Faster flame front propagation in the initial stages of ignition due to reduced ground electrode obstruction High dielectric strength - Fine 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
