NGK Iridium IX spark plugs (BR8HIX) use a fine iridium tip for extreme ignitability and exceptional anti-fouling properties suited to modified or high-performance applications. Tapered ground electrodes enhance starting and throttle response while iridium's high melting point supports long service life and consistent spark delivery, making these plugs a high-durability alternative to conventional spark plug materials.
