Hi! New to the forum. Just bought a 2007 Jaguar XK Convertible at the beginning of the year. Just crossed 100,000 miles, and looks like I'm due to change my spark plugs. Anyone done this job before? Is it an easy DIYer? Are the spark plugs easy to get to? Or difficult to remove? The car runs very well. I may just take one plug out and take a look at it before I change it. Would appreciate any feedback! Thanks in advance

 

Pretty straight forward job just make sure you have various sized extensions available.

By memory the plugs located near the tower were the hardest to remove.

At 100k miles I'd be changing not only my plugs but coil packs , cats and thermostat that is if it already hadn't been changed .

 

I found the plugs much easier to remove with a fairly hot engine.
