Right now, The Best Plug for seeing the most improvements in the way your xB will run and perform is the NGK Iridiums that come pre gapped at .044. They can be had on eBay for around 30 bucks shipped. I was doubtful till I tried them but they actually freaking worked. They corrected my rough idle and sluggish throttle response and the added 2-3 mpgs are welcomed too. From now on they are the only plugs my bB tribute will ever see.
