A clean-running engine starts with the right ignition. Spark plugs create the burst of energy that ignites the air-fuel mixture in your Land Rover’s engine cylinders. You’ll notice sluggish acceleration, poor fuel mileage, or even engine misfires if worn or mismatched. At Land Leaping Genuine British Parts, we carry factory-matched spark plugs built to keep your vehicle running strong and smooth.

What Spark Plugs Actually Do

Spark plugs deliver high-voltage current from the ignition system into the combustion chamber. That electrical spark ignites the fuel and air, powering your Land Rover with each engine cycle. Vehicles like the Defender rely on the right heat range and gap size for clean performance and steady idle. Aftermarket plugs may seem cheaper, but often cause inconsistent combustion and reduced lifespan.

Know When It’s Time To Swap Them Out

Rough starts, engine hesitation, or poor acceleration are all signs your plugs may be due. Most drivers replace them every 30,000 to 60,000 miles, depending on use and plug type. While replacing them, also inspect your ignition coils for wear or heat damage, as both work closely together. A full ignition refresh can improve performance and reliability noticeably.
