upp will last about 3-5 years and then need replaced. but any billet style with rubber boot is about the same way.
my personal fav is the trinity intake 2 piece, UPP, chariot. and there used to be a set with a center divider in it that worked well. a lot of them just have the wrong angle and/or the wrong placement of the boot to work worth a shit, OR they are the leakmaster internal boost bottle bla bla bla bull shit ones.
