NGK (2667) BKR7EIX Iridium IX Spark Plug
NGK iridium plugs represent the ultimate evolution of spark plug technology and performance. The
iridium center electrode is both stronger and harder than platinum. This allows NGK engineers to
design an ultra-fine (0.6mm)center electrode reducing the voltage requirement for spark. This allows
for a brighter, stronger spark from your existing ignition system. The ground electrode has a tapered
cut at the firing end which reduces quenching for better flame core growth and increased ignitability.
The combination of fine wire center electrode and tapered cut ground will increase performance,
improve acceleration, and fuel efficiency.
