My old boots were worn out and just squeezed off when I tightened the clamps. These fit and sealed great .

My stock boots were looking pretty wimpy after 20 years, the riffraff boots are thicker and nice and fit perfect. would recommend

Worked great. My only regret is I should have bought the complete boot kit. Buy the plenum reinforcing rings too while you are at it.

5 Plenum CAC boots
Posted by Jeff Hammond on Aug 3rd 2020
I had replaced the factory boots recently and they were still in decent shape but decided when I ordered a set of billet plenums for my 7.3 power stroke from RiffRaff to order their plenum boots also. I have to say that I was impressed with how high the quality And superior RiffRaff’s product was over the factory product. Again thank you Clay and your team for providing a superior product!

Boots appear well made, fit great with no cutting mods. Should last at least as long as original (19 years).

Bought a new set for installation with my blade runner. A bit tough to get installed at first, but hopefully will ease up after some heat cycles.
