The NGK Iridium IX LFR7AIX is a fine-wire iridium spark plug sold in a box of four. Its 0.6 mm iridium center electrode and tapered cut ground electrode are built for strong ignitability, easier starts and sharper throttle response, and iridium's high melting point holds up in hot-running engines. It suits tuned cars and personal watercraft that call for this heat range, such as the Mitsubishi Lancer Evolution and supercharged Yamaha WaveRunner SVHO models. Against platinum plugs it lasts longer and resists fouling better; NGK's own Ruthenium HX line is the step up for maximum durability.

Owners of turbocharged cars and supercharged personal watercraft fit these as a routine upgrade and report clean starts, steady idle and smooth running. Most criticism centers on cost and on plugs that arrive with the wrong gap or heat range for the application.
NGK Iridium IX spark plugs are made for performance enthusiasts. They are designed to deliver strong acceleration, high fuel efficiency and durability. The plugs offer extreme ignitability and exceptional anti-fouling.
The center electrode is a fine iridium wire that is six times harder than platinum. Iridium alloy has an extremely high melting point. A tapered cut ground electrode improves starting, idling and throttle response.
