Intake plenums boots
Does anyone know if they make plenum boot to adapt a 3inch superduty spider to the 2 inch obs plenums?

No, but billet plenums are so cheap it would be wise to just swap them out.

I installed these on my 00 f250

If you are swapping in the SD turbo, go ahead and change the plenums. They would probably be cheaper than the boots

As I recall the early 1999 series 7.3 Super Duty had step down plenum boots… although not sure on the exact size. Wanna say the bottom end fit the OBS intake runners and the other end hmmm not sure if they were 3”. Have a look at RiffRaff, they have a ton of nice stuff!

You have the eight bolt plenums/heads correct?

not sure they have the same bolt "pattern" as the 10 bolt heads, I don't have 8 bolt heads to check for you,

Riffraff redesigned their plenums to fit all head bolt patterns and plenums. Now you just choose 2" or 3".
