Spark plugs X300 4.0
Apologies in advance for dragging up this "which spark plug" question, but looking at previous threads still confuses me.
When I search online for the spark plugs for my 1995 X300 4.0 litre, I am advised that Champion RC9YCC are recommended. However, my handbook recommends RC89 PYC, the latter being platinum and more expensive than the others.
Anyone clarify or advise please?
Thanks.

Hmmmmm
Just checked my owners manual and it calls for RC9YCC for all of the 6 cylinder X300s.
Where are you located? I wonder if this varies by market?
Various technical bulletins from Jaguar mention only standard type Champions....although a higher heat range was recommended.
I'd go with standard type plugs and see how you like 'em. Personally I've tried both standard Champions and platinum NGKs and couldn't see/feel/hear any difference in the way the car performed.
Others, though, report quite the opposite with some reporting much better results with one type or the other.
I can't explain it.

The plot thickens somewhat as, although myself and the car are in Spain, it was originally registered in Florida USA and the owner's 'Vehicle Care' book originates from there so it's a bit odd that your book's recommendations differ from mine.
We are talking about the 4.0 litre are we? If so, my confusion is perhaps understandable!
Thanks again.

Yes, odd.
It appears that Jaguar had a change of heart about spark plugs....or perhaps some manuals were published with incorrect info? Or...who knows? With enough time and effort we could probably get to the bottom of this mystery.
But, it's of little consequence in the grand scheme of things. It does pique my curiosity a bit, though :-)
