Land Rover Part Number: RTC5628 - Ignition Coil - V8
RTC5628 is an ignition coil for V8 engines. Fitted to the ignition system on 3.5L V8 twin-carburettor and EFI engines, this Lucas electronic coil supplies the high-voltage pulse required by each spark plug to ignite the air-fuel mixture. Mounting orientation can vary by application - early Range Rover Classic installations use horizontal or vertical mounting - so replacement units must match the original electrical characteristics and mounting arrangement to maintain correct ignition timing and spark energy.
