A degraded or cracked HT lead on this cylinder can cause misfires, poor cold starting, and rough idle, symptoms that are often misdiagnosed on the V8. Replacing with the correct lead ensures proper resistance and insulation spec for the ignition system.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned specifically for the Number 1 cylinder position on the Land Rover V8 engine\u003c\/li\u003e\n\u003cli\u003eCorrect lead length and routing geometry for direct fitment without modification\u003c\/li\u003e\n\u003cli\u003eMeets OEM specification for resistance and high-voltage insulation\u003c\/li\u003e\n\u003cli\u003eHT leads are typically replaced as a full set of eight - check remaining leads for cracking, carbon tracking, or swollen boots\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 P38 (1995–2002), both with V8 petrol engines, Number 1 cylinder position.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
