2004 Jaguar XJR Question: tune-up
Answer #1DaveJHM May 22, 2011, 22:05Master
Jaguar says to replace the spark plugs at 100,000 miles. I tend to go a bit lower - I would suggest getting factory plugs out around 60,000 miles.
This vehicle has coil-on-plug ignition too. The coil boots may need replaced when you change the plugs.
