I was looking at these kits as well. My vents are trashed and it will hundreds to get them clean and stock. I've watched a few YT videos on the install and it looked pretty straight forward but i've read mixed reviews on this forum about the kits.
I also found this 1pc kit from One Piece Products. It's a little more $$
