I am going to replace the spark plugs in my 01 XKR soon. In researching NGK Iridium plugs, I get much conflictinginformation. Has anyone used the NGK Iridium plugs on the 4.0 supercharged motor? What plug did you use?

 

Yes i have NGK Iridium in my XKR.

I have not had any issues with them at all.

 

Do you have the part number for the plugs you used?

 

i used part# BKR6EIX

I got them from shucks.

www.partsamerica.com

i know i could have got them cheeper. but some times convenience is worth the price.

 

Thanks for the info. I'm going to order some. My mechanic wants to charge me $28 ea. + labor to install them.

 

That is WAY OVER PRICED. BUT...... he is throwing in labor.

your cost
28.99 x 3 = 231.92

6.99 a plug x 3 = 55.82

you cant blame the guy for trying to make a buck. but if you are able to do it yourself, your better off. Have you done plugs on your jag before? it takes almost no special tools and is about a 45min job. for 176.10 its worth the 25mins.

 

Gee my XK8 has 8 plugs. Are you running a smart car engine?? Sorry couldn't resist.. Merry Christmas.

 

I bought the plugs for the $6.99. My mechanic lets me buy parts if I can get them cheaper and just charges labor for the work. He is really pretty good. I may give it a try though, as I have replaced plugs before, but not on a Jag.

 

LOL!!! WOW nice typo.... sorry....

GreenJewel: Please note that you are correct... Marry Christmas.... NOT HAPPY HOLIDAYS! I love not being PC!


Its Christmas morning and my crazy neighbor is washing his car in the snow!
