{"product_id":"lead-high-tensn-ignition","title":"Lead - High Tensn - Ignition for Discovery 2 (1998 – 2004) No4 - To Number 4 Cylinder – NGC103770","description":"\u003cp\u003eNGC103770 is the high-tension ignition lead supplying spark to cylinder number 4 on the 4.0 and 4.6 litre V8 engines fitted to the Discovery 2 and Range Rover P38. Each lead routes high-voltage current from the distributor cap to the correct spark plug, and a degraded or cracked lead on cylinder 4 will typically cause a misfire, rough idle, increased fuel consumption, and possible fault codes on the engine management system. Replacing individual leads as they fail, rather than the full set, requires correct cylinder-specific identification to ensure proper routing and length.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-tension construction rated to handle the ignition voltage demands of the Rover V8 distributor system\u003c\/li\u003e\n\u003cli\u003eCylinder 4 specific lead - correct length and routing for the V8 firing order\u003c\/li\u003e\n\u003cli\u003eSupplied to OEM specification under genuine Land Rover part number NGC103770\u003c\/li\u003e\n\u003cli\u003eConsider replacing all eight leads as a set if the ignition system has high mileage, as adjacent leads are likely to be equally degraded\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Discovery 2 (1998–2004) and Range Rover (1995–2002), both with V8 petrol engines, cylinder 4 position.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
