Make sure you gap them!
Decent plugs for the price, but make sure you gap them! Gas milage seems good. They don't come pre-gapped. I Assumed they did and threw them in the Audi A4 as i couldn't find my gap tool. The car started, idled and drove fine but stuttered badly when hard accelerating. I pulled the plugs, checked the pre-set gap and they were well over spec. Decreased the gap and now drives perfect. I'm used to the pre-gapped auto parts store plugs out the box, my bad. Overall good plugs as long as you keep that in mind. Too early to tell how long/how well they'll perform.

Autolite app plugs
Plugs worked great in my 13 chevy cruze lt with the turbo engine. I however didn't keep them in my car because I put iridium plugs back in since my car has a tune in it

They work
Purchased for a 2012 VW GTI. Had to adjust the gap quite a bit to fit my vehicle specs, but they work fine.
