Spark plugs

[S6 Devil]

I've owned the XJR for just over 2 years now and am wondering when to get the spark plugs changed? Is there a set timescale for this or something to look out for? The car has done 100500 miles and has been well maintained with FSH. I don't know when the spark plugs were last changed.

I have been looking at plug options. There seem to be Jaguar part number NCA3850HA2 and two NGK options 1. Recommended PFR6G-13E 2. Upgrade BKR6EIX-11.

Any thoughts on the NGK...anyone used these or have you stuck with Jaguar parts?

The plugs depending on that ones are in there last some time.
Take one out and have a look at the condition

I'd go for NGK option 2 the BKR6EIX-11

The service schedule calls for spark plugs to be changed every 30k miles on the supercharged X308. Worth a look on ebay for cheapest price.
