Cheap good sparkplugs
Really good price for a good NJ one performance sparkplug, these were for my mom's expedition, if it was going in my vehicle I would have went with platinum plugs but I drive way more miles a year than her.

Worked as expected
Autolite's in a Ford is like AC Delco in a GM; it just works, all the time!

Great plug
I don't know if these will have problems after a few thousand miles but right now my truck is running like it should. So much better than before I put these in with new coils. So at least initially, these are great plugs!

Defective "manufactured in China" Autolite plug made my car misfire
Horrible experience! I bought 4 for my 2004 Ford Focus. Right after I installed them, my car started running erratically. It would hesitate and hiccup; on the highway it would pull and then slow up hills and start to stutter. After 15 miles, a flashing engine light came on. I thought my high-mileage Focus was finally showing its end. However, I did an OBD scan and found that the first cylinder was misfiring. Brand new plugs right out of the box - these say "designed in USA, manufactured in China."When I got back home from my 60 mile trip, I retrieved my used plugs, an earlier edition of Autolite 103 that were manufactured in the USA, and installed them. They work perfectly. So, the Chinese plugs are defective.I've kept the plugs for four months before installing them, so I'll see if Amazon will refund me and look into this issue. I could have been stranded 30 miles away from home and had damage done to my catalytic converter and fuel lines because of this Autolite defect.
