Frequently Asked Questions
What spark plugs does a Land Rover Discovery Sport use?
The Land Rover Discovery Sport (L550 FL) uses NGK ILKR8Q7 iridium spark plugs. The gap should be set to 0.7 mm. You need 4 plugs for a full set.
How often should I change spark plugs on a Land Rover Discovery Sport?
Every 60,000 miles for iridium plugs. Iridium and double iridium plugs last longer than standard copper or nickel plugs.
Can I use a different brand of spark plug in my Land Rover Discovery Sport?
Yes, as long as it matches the exact specification — same heat range, thread size, reach, and gap (0.7 mm). NGK ILKR8Q7 from any major manufacturer (NGK, Denso, Bosch, Champion) will work.
What are the signs of worn spark plugs?
Rough idle, poor fuel economy, hesitation during acceleration, engine misfires, and difficulty starting. If your engine management light comes on with a misfire code, spark plugs are a common culprit.
