Duralast Direct Ignition Coil C1395

One duralsat Ignition Coil is new. Other one is only used for 2 or 3 days. Other 4 are used. I bought and replaced all the old Ignition Coils when engine of my Gmc envoy started but the problem was something else. But I will give you all 6 to you. You can try by your self for other 4 if they are good or not.
