Videos (1)
The S&B 83-2011 is the hot- and cold-side boot kit for a 1999.5–2003 7.3 Powerstroke. It replaces the intercooler couplers and the plenum boots. Ford used both 3-inch and 3.25-inch outlets, so both sizes are in the box.
You get two 3-by-3 couplers and two 3-by-3.25 couplers, twelve T-bolt clamps, and two hose clamps. The boots are aramid-reinforced silicone. Use the T-bolts on the metal tubes. Use the hose clamps on the plastic plenum so the T-bolt does not crack it. A split boot is a boost leak, a lazy turbo, and black soot at the clamp.
It fits 1999.5–2003 F-250 and F-350 trucks.

The picture show eight boots but the description say four. Which is it four or eight.

Some trucks need (2) 3”x3.25 couplers and some need (2) 3”x3” couplers. We included 2 of each to ensure you have the correct boots.

So does the kit come with 6 or 8 boots?

The kit actually comes with eight (8) boots total. A standard 7.3L only uses 6 boots, but because Ford used two different sizes for the lower intercooler connections depending on the truck, S&B includes both the 3" x 3" couplers AND the 3" x 3.25" couplers. This way, you will have the correct size no matter what and you will simply have two boots left over
