Hello,
Always wanted an XJR to add the my two 2000 Red VDPs and now I have one. It definitely needs some work so am starting with the engine top end. It needs a knock sensor but while the supercharger if off, I want to replace the valve cover gaskets and spark plugs as well. When looking for plugs there are sometimes two plugs by the same manufacturer that are listed and fitting an XJR. I am not opposed to NGK, Bosch, or Denso plugs but want to be sure that I'm buying the right ones for an XJR.
Are they actually different than the general ones for a N/A engine? Denso has two plugs that are listed as replacement though one has a .40 gap and the other has a .44 gap.
Looking forward to getting this car road worthy! Thanks much for the assistance.

 

What, are you parking them all out by the ball-field over there?...lol...I'm supposed to do some contract work there, but they keep pushing it back.
The old spec are NGK PFR5G-11E.., gap .043, which yes are the same for N/A as SC. These ignitions burn so well since the mid 90's, plugs don't vary much, except for what they are burning.

 

The BOSCH9652OE Fine Wire Double Iridium at RockAuto would be my choice.
They are a little over 5 bucks apiece and they really last.

 

Thanks for the replies guys! I'll be placing the orders for parts right away including transmission filter and gasket.
BTW, I assume the XJR takes Pentosin fluid as well but let me know if I need different fluid.

I also have my son's 1999 silver XJ8 in the yard as well. We replaced the rear engine seal two weeks ago and he needs to drive it to his house now! Highhorse, are you from this area? I do indeed live a few miles from the Stripers ball park.

I would also do these things while the s/c is removed:

1. Replace the coolant hoses in the valley
2. Replace the part load breather tube. Supremely brittle plastic, you likely have already damaged it if you pulled the s/c. This is a vacuum line, so you don't want it to leak.
3. Clean/inspect/replace (?) the injectors. I didn't do this on mine when I removed the s/c to replace the hoses, but I wish I would have (newbie at the time). I'm not sure what maintenance is required, but I would recommend addressing the injectors while the s/c is out. The forum can advise you on what to address with the injectors, or replace them, etc.

 

I'm not from there, but I'm in an out of N GA, been up in Blue Ridge a lot lately...last week as a matter of fact. My accountant is from up around your area, he has family in Dahlonega.

 

So you must be around Gainesville or Orlando?
No wonder you are trying to escape!

 

Eastern Orlando, it's getting to look like Chicago down here...want to move to Charleston.

 

I absolutely agree! I travel down that way fairly frequently and have noticed not only the increased
traffic, but also the attitude of the drivers. Young girls driving around like they are in an Indy 500
race, and young men with no courtesy in their driving style at all. I suspect that element is present
in most of the higher populated cities. I have visited Charleston on multiple occasions and have
always felt it was one of the best port cities. I love that big bridge and the tree lined streets.
