What are the best spark plugs for my Jeep Wrangler TJ 4.0?

Ok XP985's on the way, we'll see if they're the greatest thing since sliced bread. Just checked my mileage with the current champion 7034's & right at 17 mpg so they certainly aren't shot but been in the 80-85k miles.
BTW apparently Rock Auto isn't shipping to AZ any longer?? IDK why but I'm sure our stupid Governor Hobbs has something to do with it.

Wow,
That's a switch, normally there are items you can buy in Az but can't get in Ca.

Reasons are different: In CA it's because of the Enviro-Nazis. AZ is a tax dispute that's going to take a few years to work through the courts.

For people who don't know, RockAuto is a drop-shipper. They don't own any warehouses or inventory (they say); they just contract with National auto-parts warehouses to ship items, for them.

I get it, The Nazis in Ca won't allow chlorine in brake cleaner but put chlorine in the drinking water.

And that's the least of the hypocrisy.

Ugh, so Amazon 'lost' one of my Centric rotors. Got a refund so reordered it along with the XP985s, well they all show up in a big box. Open it & two plugs are out if their little boxes & have been bouncing around inside the big box along side the rotor. Stupid Amazon...they appear ok but I'm sure the gap will be off now.

Amazon's packing is completely brain dead. You should check/adjust the gap anyway, but I'd return the ones that were loose. Idiots..

XP985s pretty darn impressive! Of course the old champions were so bad I'm surprised she had been running so well. Now I step on the gas & it actually responds. Super smooth idle.
