Anyone try the E3 spark plugs

Curious to know if any Aveo owners tried them and their comments

My buddy tried them on his 97 cavalier, it's an automatic, was chirping going into second gear, now it chirps going into third gear too now.
He said it was defiantly noticeable.

I put them in my wife's old CTS. They were great at first but after about 20k miles it developed a miss and stumble that went away as soon as I put new NGK's in.
