Worked great, not pre-gapped.
in 2 months
These worked great in the car, however were not pre-gapped. When purchased the Autozoner stated they would already be gapped for the vehicle I was installing them on. I always double checked and two of the four were off by as much as .020 inch. After properly gapping them and installing, they worked great in the vehicle.
What kind of vehicle do you drive? 2007 Toyota Corolla
