The y boots fit perfect! Highly recommended! My 7.3 needed these boots bad. Better made than factory an better price! fast shipping excellent customer service,Thanks again riff raff!

Seem to be better quality than dealer item. no issues with any sizing. Overall perfect replacement for over priced dealer part.

A must have for an early 7.3 build...fit perfect.

didn't realize how bad my old boots where till I tried to pull the Y pipe out. ford sure is proud of there obsolete product and this steps up the fitment and reliability. another must on the 7.3 list.

Great fit, Excellent construction these will last.

My boots were in bad shape, but I did not realize how bad until I installed the new RiffRaff boots and immediately added 5 lbs. of boost to my truck. I was hitting 14-15 on a hard pull and after this install, I consistently saw 20-21 lbs! They are extremely affordable, easy to install, and really nice quality. Buy them!

Super quality upgrade for your disintegrating y boots.

replaced my stock boots when I rebuilt the turbo, stock ones were soft and worn, these are good quality and should hold up for quite some time.

great item much better than stock!!
high quality..thanks
