Genuine Part
Genuine: Original manufacturer part. This product is the original part designed and produced by the vehicle manufacturer.
HT Ignition Lead - No.5 Cylinder - high-tension ignition lead from the ignition coil and HT lead assembly, carrying the secondary ignition output to the spark plug at No.5 cylinder of the 4.0L and 4.6L Rover V8 petrol engine.

Leads in a V8 set are made to individual lengths matched to the routing of each cylinder position, so this lead is specific to No.5 and is not interchangeable with the leads for the other cylinders. Both ends carry insulating boots: one seals over the spark plug insulator, the other over its matching high-tension terminal.

HT leads are a wearing item. Insulation hardens and cracks with repeated heat cycling and conductor resistance rises with age, which typically shows up as a misfire under load, rough idle, or poor starting in damp weather. A degraded lead can also track to earth or to a neighbouring lead, so all eight are normally renewed together to keep secondary resistance consistent across the engine.

Frequently asked questions

What is the NGC103780LR HT ignition lead?
The NGC103780LR is the high-tension ignition lead for No.5 cylinder on the 4.0L and 4.6L Rover V8 petrol engine. It carries the coil's secondary output to the spark plug at that cylinder. Genuine Land Rover part, with insulating boots at both ends.
Is this lead specific to No.5 cylinder?
Yes. Leads in a V8 set are made to individual lengths matched to each cylinder's routing, so this one is specific to No.5 and isn't interchangeable with the other cylinders' leads. Order by cylinder number to get the right length.
Should I replace one HT lead or the whole set?
All eight leads are normally renewed together, since insulation hardens and cracks with heat cycling and conductor resistance rises with age. A degraded lead typically causes a misfire under load, rough idle or poor starting in damp weather. Replacing the set keeps resistance consistent.
Which vehicles does this lead fit?
This No.5 HT lead fits the Discovery 2 (1998-2004) 4.0L V8 and the Range Rover P38 (1994-2001) 4.0L and 4.6L V8, to VIN XA410482 on the P38. Confirm your engine and VIN before ordering.
