    BOOTS FIT PERFECTLY

    Posted by Tyler Durden on Oct 26th 2026

    I replaced my boots with these on my stock plenums (I installed the plenum inserts at the same time). These boots are fantastic. Way more flexible and "grippy" to hold on to my spider and plenums. Very happy with these boots. Zero boost leaks now.

    Nice quality

    I would have given it five stars if they were a quarter inch longer. Couldn't get the AFE Spyder to fit along with riff raff plenums without moving the hose off the plenums of a little bit where the clapms were just catching the groove.

    These boots are so much thicker than the original ones. The Ford ones have lasted me 21 ys and only now have to change them due to oil leaking. I would get new clamps if doing it again.
