Spark plug Champion or Autolite

Champions quiet redesign of their plugs to match Tempest made up my mind. It matters, and Champion is just trying to save face.

I've ran Autolites on my racecar that runs in the 7's for 20+ years with no problem. They are the only thing I trust at the moment

I used them in my 2007 Tacoma with no problems. Left them in for several years.

I put autolite's in my 2010 V6 and they've been perfectly fine.

after changing the spark plug for another autolite it stopped misfiring its still a little rough so I fear it may comeback so I just ordered some NGK plugs.

BEWARE O’REILLY’S AUTO PARTS CHAMPION SPARK PLUGS ARE WEAK AND BREAK AT THREADS AFTER HAND TIGHTENING AND THEN TIGHTENING NOT EVEN A QUARTER INCH OF A TURN, WAY BEFORE THE TORQUE SPEC AND THEY TWIST RIGHT OFF N BREAK.

Like everyone has mentioned just go back with an ac delco plug. I ran champions and had Mis fires, none of them were gapped right out of the box.

autolites are some of the worst spark plugs, grab some NGK iridium’s and it should be fine

I have a 2019 GTI with 65k km. I decided to do plugs and when I saw how expensive OEM were, I said screw that, i'm going to try the iridium auto value basic ones. I thought the difference in quality would be negligible. I ran the Autolite XP5325 plugs without gapping. All seemed fine but then when pulling on to highway under load at 3k + RPM, misfiring like crazy.

it was the Autolite spark plugs. Had car towed to my mechanic. They replaced with spec NGK and the car is running fine.
