Is there a specific type that is needed, like a standard for this application? Or just good heavy duty grease? Because im coming up to 100k and should probably do this as well.
I have been tpms free for 2 years. Got a set of take offs without em. I dont miss them. New tires will go on my oem wheels for the winter and ill have them again. Im no worse for the wear.
but if you need your spare it would be nice to have it if the other 3 would as well.
Unless you tightened the snot out of those connections, which I doubt. That is insane. Plastic would not damage the engine for the most part. Just get mushed up and shot out. I would be concerned about plugging the cat. Even then the temp should vaporize it.
