Land Rover Part Number: RTC3571 - Spark Plug - 2.25 Petrol - 7:1
RTC3571 is a spark plug for 2.25L 4-cylinder petrol engines with a 7:1 compression ratio. Fitted to the ignition system, it produces the high-voltage spark that ignites the compressed air-fuel mixture in each cylinder: the central electrode receives current from the ignition circuit and the spark jumps the electrode gap to the ground electrode. Correct electrode condition and heat range affect starting performance, combustion quality and running stability; worn or fouled plugs commonly cause misfire, rough idle or hard starting. Replace according to the service schedule or if electrode wear or fouling is observed.
Compatibility
- Defender (1987-2006) - 2.25 Petrol
- Series - 2.25 Petrol
