These handy plugs seal up the holes when you remove your COD solenoids.
Set of 17. 16 for the holes and 1 for when you inevitably drop one in to Never Never Land. 17th converts to a keychain as a reward if you don’t lose one.
Before deleting your plugs, pull unplug some of them and make sure you don’t have any codes. The COD system must be coded out completely, not just made inactive as most off-the-shelf tunes do, or else you’ll get a CEL and the car may not run right.
