NGK CR8EIB-10 Iridium Spark Plug – Stock 4948
The NGK CR8EIB-10 is a high quality iridium spark plug designed for strong ignition and stable performance. Its fine-wire iridium centre electrode needs less voltage to fire, which helps cold starts, improves throttle response, and reduces misfires. It also resists wear, so it keeps its gap and performance for longer than a standard nickel plug.
Use it as a performance-focused, long-life replacement where an NGK heat range 8, 10 mm thread plug is specified.
- Fine-wire iridium tip for a clean, reliable spark
- Resistor design to reduce electrical noise that can affect the ECU
- Pre-set 1.0 mm gap for consistent ignition
