The NGK Iridium IX BKR7EIX (stock number 2667) is a one-step-colder-than-stock iridium spark plug sold in a box of four. Its 0.6 mm iridium center electrode and tapered ground electrode give a stronger, more focused spark than standard copper or platinum plugs, and the fine tip resists wear far longer. It is a common upgrade for turbocharged, supercharged and high-compression engines, and it cross-references to Denso IK22, Champion 9801 and Torch K7RTP. Owners rate it highly for smooth idle and throttle response; the main trade-offs are the higher cost than standard plugs and the need to gap and torque it correctly.
