Detailed Description

Walker 924-2042 is a spark plug wire set engineered for Land Rover Discovery and Land Rover Range Rover models within the listed fitment range. The ThunderCore PRO line focuses on OE-style construction and materials, including high-temperature silicone insulation and stainless steel terminal components, to maintain consistent spark delivery under demanding engine conditions.

What It Helps Address

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak ignition transfer
• Rough idle from deteriorated wire insulation or terminals
• Voltage leakage from cracked boots or aging wire jackets
• Intermittent ignition performance on Land Rover Discovery and Range Rover models

Installation Notes

Match each wire to the original routing before removal to avoid crossfire or incorrect cylinder connection. Inspect spark plugs, coil connections, and routing clips during service, and apply the included dielectric grease to boot contact areas as directed by standard ignition service practice. Verify fitment by year and model before installation on 1999-2004 Land Rover Discovery or 1999-2002 Land Rover Range Rover.
