Overview
If you own a 2010–2012 Range Rover Sport V8 or Discovery LR4 V8, your ignition system is critical to engine responsiveness, fuel efficiency, and cold-start reliability. Factory spark plugs degrade over time, leading to misfires, rough idle, and increased emissions.
These genuine Laser Iridium Spark Plugs are direct-fit replacements engineered to OEM specification. Dual iridium electrodes resist erosion, maintain precise gap tolerances, and deliver consistent ignition across the full RPM range—whether you're towing, climbing, or cruising on-road.
From Japan's most trusted ignition specialists, this four-plug set restores your V8's efficiency, responsiveness, and reliability. Backed by our 30-day money-back guarantee and 12-month warranty, upgrading your spark plugs is the simplest way to preserve your Land Rover's performance foundation.

Installation Notes
⚙️ Installation Overview
Difficulty: Intermediate · Time: 45–75 minutes · Tools: Socket set, spark plug socket, gap tool, ratchet wrench
- Ensure engine is cool. Disconnect the negative battery terminal.
- Remove coil packs from cylinder head (note firing order for reassembly).
- Using a spark plug socket, unscrew old plugs and inspect for carbon buildup or wear.
- Verify gap on new plugs (should be 0.032–0.035″ for your V8) using a feeler gauge.
- Install new plugs hand-tight, then torque to 20–25 Nm using calibrated socket.
- Reattach coil packs in correct firing sequence.
- Reconnect battery and start engine to confirm smooth idle.
- Clear any diagnostic codes with OBD-II reader if needed.
⚠️ Important: Do not force plugs into cylinder head. If resistance occurs, stop and seek professional assistance. Incorrect installation can damage the cylinder and void warranty.
