My Cobalt has 61k I bought the new ACDELCO IRIDIUM sparkplugs, it seemed to help the engines power but after about three weeks, the power seems to be back to where it was before I installed the new plugs. Not sure what that's about??

Rated 5 out of 5 by Dako 41-110 highly recommended for 5.3l vortec
I replaced 748gg AC delco wires and 41-110 acdelco spark plugs also acdelco spark plug shields on my 2003 chevrolet suburban1500 ls 5.3l vortec Vin:z
After 100000 miles and it runs as new again
These new iridium spark plugs run smooth perfect match for my car. If you decide to change spark plugs use only AC Delco on Chevrolet . Used to have Bosh platinum and it run poor at low idle speeds
