NGK Iridium IX spark plugs (BCPR7EIX-11) combine a fine iridium center electrode with a tapered ground electrode to improve starting, idling and throttle response. Designed for enhanced ignitability and anti-fouling, iridium's high melting point and durable tip construction extend service life and help deliver better acceleration and fuel efficiency for modified or performance-oriented applications compared with standard plugs.
