These plugs are really great. I have a lot of horror stories about how hard it is anti-vibration plugs to install. Not with this. They have a small cut where it is cooler to so they are super easy to pull through. I have not even used a pair of pliers. Fingers were enough. It is also gone very quickly. Not longer than screws. The also make a difference right now you can hear only the air as it passes through cooler for and no other sounds. You do not look too bad, I have used it on my Window Panel and is pretty good, no worse than screws. Correct a good buy. Marty :)
