Which spark plugs for my 2002 XJ8 ??

Iridium is always a good choice!
Your car will need NGK Iridium IX BKR5EIX-11, unless it's a 4.2 Liter engine.

Sparkplug NGK thread on forum
Hi
Look at this thread on sparkplugs for your XJ8:
https://www.jaguarforums.com/forum/x...m-plugs-63823/
One of the posts has the NGK sparkplug guide (post 5 or 7). We have been using NGK Iridium for almost a year now - no problems to report. Also super low price on the advance auto website with coupon code A123 (40% discount).

Bosch has not had a problem. I have had the plugs in my cars for years. The problem on the most part was improper install not the plug. This is another K&N fiasco and an injustice.

We bought these off of amazon for $6.25 each because it gave us enough for free shipping on a larger order of other stuff.
They came gapped at .040

The question I have is about gap.
The Bosch iridiums (Buy Bosch Iridium Spark Plug 9603 at Advance Auto Parts ) say they are pre-gapped - don't gap. Can these be used like that?
The NGK iridiums (Buy NGK Iridium Ix Spark Plug 5464 at Advance Auto Parts ) from Advance Auto Parts are gapped at 0.052. Do they need to be gapped?

Hi OldMike
The NGK plug gap is preset to the correct gap per statement by NGK on their partfinder webpage:
http://www.ngkpartfinder.co.uk/car_c...ra.php?id=5625
Also if you order the NGK type 5464 from Advance Auto Parts website and use discount code A123, you will get a discount of about 40% ($20) and will be able to do a store pickup (no shipping charges).
Your cost will be $36.72 (versus $56.72) for all 8 spark plugs (price was $7.09 per spark plug less 40% = about a net of $4.25 each.

Gentlemen...if you would care to look at Jaguars original specifications you will notice that NGK were fitted as OEM plugs.
For the 00-02 models the correct plug is
03/00 - 03/02 JAGUAR XJ8 4.0L V8, EFI, DOHC, 32V, 216kW, 393Nm AJ27
NGK PFR5-6G-11E gapped at 1.1mm or 0.04331"
The Iridium equivelant should be BKR5EIX-11....these are pre-gapped DO NOT alter!
Or PFR6G-11 eqivelant Iridium is BKR6EIX-11....pre-gapped DO NOT alter!
Correct torque level for tightening is 18-20nm
The use of Nickel Silver anti seize is reccomended by The Company.
Only apply to lower half of threads and 180 degrees....I use a small paint brush.
make sure your plug wells are clean dry...if oil is present, it's time to replace you head cam cover seals and plugs seals.
Always mark number your coils so they go back in the same place and handle the COP wiring CAREFULLY as at this age it has become heat hardened.
Use electronic cleaner/ lubricant spray on the plugs and you are in business.
Despite many comments, the correct use of fuel type goes a long way to seeing these car run correctly....you should be running 92-95 octane low ethanol content fuel for best results.
There is an awful lot of 'much ado about nothing' with this issue ;o))
Stick to the best spark plugs in the world and you will never have any problems.
All being equal of course in regards to other parts of the ignition system....

More great information - thanks. I'll get some nickel silver anti-seize tomorrow.
When I replace the spark plugs, is there any reason to replace the wires, too? As a matter of habit, I've always replaced both but only when dealing with really old cars (like my 57 Chevy, e.g.). Just wondering what everyone's opinion on that is. My Jag is only 10 years old!

Almost any lubricant including a smear of engine oil from your dipstick would serve satisfactoriily as anti-seize.
