While I was working on the car this week I pulled a plug out of the front bank and it's looking pretty worn.
A couple of questions..
First, are the NGK Iridium IX (BKR6EIX-11) plugs worth it? Has anyone any opinions/reviews of them? Mostly wondering if they last that much better.
Second, should I change the rear plug wires while I've got that part of the engine apart? And what does everyone think of the NGK plug wire sets? (TE65)

Thanks

BTW, this is a '99 V6

Noone's tried IX plugs in their V6's?
