What is the spark plug model for Jaguar XFL?
3 Answers
Jaguar XFL uses NGK iridium platinum spark plugs, model: ILKAR7C-10. Depending on the vehicle model and batch, the specific spark plug model used may vary slightly. Spark plugs are crucial components in a gasoline engine's ignition system. They introduce high voltage electricity into the combustion chamber, causing it to jump across the electrode gap to create a spark, thereby igniting the combustible air-fuel mixture in the cylinder. They mainly consist of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. Spark plug replacement cycle: Under normal maintenance conditions, replacement is recommended every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's advisable to follow the owner's manual. You can refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.
I've been driving a Jaguar XFL for several years and found that the spark plug model specifically depends on your engine type and year. For example, the 2.0-liter Ingenium turbocharged engine after the 2017 model often uses NGK IKR9H8 spark plugs, but if equipped with a 3.0-liter V6, you might need a Bosch model. Why is this important? Because the condition of spark plugs directly affects engine vibration, fuel consumption, and acceleration. I recommend checking your owner's manual first or finding the matching model on Jaguar's official website using your VIN code—don’t swap them randomly to avoid engine issues. You should inspect them every 60,000 km or so. Last time I didn’t replace them on time, it caused unstable idling and cost me a lot in repairs. Remember, using specialized tools for installation can extend their lifespan—if you can’t handle it yourself, go to a specialized repair shop.
Having serviced many Jaguar vehicles, I can confirm that spark plug models like NGK IKR9H8 are standard for the Jaguar XFL 2.0T engine, though specifications may vary across different model years. Pre-2020 models had slightly different variants, so it's best to cross-check with the vehicle code. Replacing spark plugs isn't trivial – electrode gap and heat range compatibility are critical to prevent misfires. I've encountered cases where owners installed incorrect models, triggering check engine lights and fuel wastage. A pro tip: always scan engine data with an OBD diagnostic tool before proceeding to avoid rework. Also, adhering to the 60,000-km maintenance interval prevents unexpected breakdowns and ensures smooth engine operation.
