These work perfectly in Chevrolet 5.3 motors. Made in Japan, NGK is the spark plugs I use in everything. Small motors too..

Runs great
I was concerned about the plug gap being .40 instead of .60 Did some research and GM changed the gap. Car runs great with new plugs and wires

Good plug, but better to buy NGK laser iridium
These plugs are OK. I gave a 4 * rating not because the plugs are bad, but because for the small increase in cost you really should get the NGK laser Iridium which last 100k between changes whereas these last 50k. The only reason I put these on my Ford Taurus with 100k miles was because the car most likely won't be driven that much. The time and difficulity involved in replacing the back 3 plugs is greatly offset by the small price difference in NGK plugs if you are going to be driving the car a lot. My Nissan had 100k on oem NGK laser irridium and I replaced them only because Nissan recommended replacment at 100k. But the plugs showed absolutely no sign of wear. So I would say NGK plugs are a great buy.
