The Ford F4TZ-8287-A is the OE clamp for the 3-inch plenum boots on a 1999.5–2003 7.3 Powerstroke. It locks the valley boot to the intake plenum.

Each boot uses two clamps, and the truck has two plenums, so a full replacement is four clamps. This part is sold individually. A stretched factory clamp lets the boot walk and leak boost at the spider. The Ford clamp matches the original diameter, so it seats on a stock 3-inch plenum without adapters.

It does not fit the early 1994–1997 trucks. Those plenums are 2.25 inches and use F4TZ-8287-AAA.

Fitment

• 1999.5–2003 Ford 7.3L Powerstroke
• 3-inch plenum boots
• Genuine Ford F4TZ-8287-A

Replace the clamps with the boots. A new hose on a worn clamp will still leak.
