2006 Pontiac G6
I installed this set of spark plugs in my 2006 Pontiac G6 (4 cylinder) just past 100,000 miles. Since then I've driven it for about 6,000 miles with no problems. The car runs great. I didn't really see much improvement in fuel mileage, but that's because the car already had iridium spark plugs from the factory (and they still looked pretty good). I have nothing negative to say about them. They work as designed, and I got them from Amazon at a good price.

Great replacement parts by BOSCH
Easy to install. Mostly pre-gaped. Just chek the gap before installation. If you haven't done this type of change before I recommend watching ChrisFix, Eric the Car Guy, or Engineering explained on youtube. ( Not paid to mention these names) They have just been good references that I use to when doing work on my car.

Happy camper
These are great. I read around trying to find spark plugs everyone else was happy with on their Hummer H3s and was not disappointed with these. I am noticing about 1.5 more mpg on my fuel economy when I haven't changed anything else. So I guess I can attribute it to these spark plugs.

Don't see the need for high dollar plugs...
Haven't noticed a difference from these plugs versus factory Hummer H3(GM) plugs I removed. Replaced at 90K miles when tuned up H3 and it's still rough start and fuel economy not ideal.
