NGK IFR7G-11KS Iridium Spark Plug – Stock 7746
This NGK iridium spark plug gives a strong, consistent spark for reliable combustion. It helps cold starts, smooth idle, and stable performance under load. The fine-wire iridium tip needs less voltage to fire, which supports tuned engines and sustained high RPM use. It also lasts longer than standard nickel plugs.
Key benefits
- Fine-wire iridium centre electrode for clean, reliable ignition
- Platinum-tipped ground electrode for long service life
- Resistor design reduces electrical noise for stable ECU signals
- Pre-set 1.1 mm gap for easy installation
