6.4 Powerstroke Intercooler Boots: Fitment and Kit Guide
.
Table Of Contents
Mammoth’s 6.4L Powerstroke intercooler boot kit fits 2008–2010 Ford F-250, F-350, F-450 and F-550 trucks with the 6.4L diesel engine. It includes four five-ply silicone boots and eight stainless steel constant-tension T-bolt clamps. Choose black, blue or red on the 6.4 Powerstroke intercooler boot kit product page.
Before ordering, confirm the engine, inspect the charge-air system and check whether you need boots, pipes or coolant hoses. These parts do different jobs, even when they fit the same model year.
Which trucks does the 6.4 boot kit fit?
| Ford truck | Model years | Engine |
|---|---|---|
| F-250 and F-350 | 2008–2010 | 6.4L Powerstroke diesel |
| F-450 and F-550 | 2008–2010 | 6.4L Powerstroke diesel |
This is a 6.4L application. It is not the kit for a 6.0L or 6.7L Powerstroke. Mammoth does not split this 6.4 boot kit by an early/late build date. If your truck has aftermarket charge pipes, a different turbo arrangement or other changes to its factory charge-air connections, check compatibility before ordering.

What comes in the kit?
- Four five-ply silicone intercooler boots
- Eight stainless steel constant-tension, spring-loaded T-bolt clamps
- A choice of black, blue or red boots
This is a boots-and-clamps kit, not a replacement intercooler or charge-pipe set. Match the parts you need to the fault you have found: a damaged pipe or intercooler needs its own repair.
The reinforcing layers are one part of a boot’s construction. Fit, condition and correct installation matter too. A ply count alone does not tell you the safe test pressure for a complete charge-air system.
For a broader comparison of materials, reinforcement and clamps, read how to choose a diesel intercooler boot kit. For replacement-clamp sizing, see how to measure a hose clamp.
When should you inspect the intercooler boots?
Intercooler boots connect sections of the charge-air system. A split boot or loose connection can let pressurized air escape. Reduced power, an unfamiliar hiss under load or an underboost warning are reasons to investigate, but they do not identify a boot as the cause on their own.
With the engine off and cool, look for visible splits, abrasion, a boot that has slipped out of position, or a displaced clamp. Oily residue around a joint can be a clue worth checking; it is not proof that the boot has failed.
Have a qualified technician diagnose the leak before replacing parts. Charge-air testing should follow the vehicle’s service procedure and the test equipment’s instructions and limits. Do not choose a test pressure from a boot’s advertised rating.
Our guides to boost leaks and bad intercooler symptoms explain why similar symptoms can have different causes.
Installation: fit and clamp placement matter
Correct installation includes checking the condition and alignment of the mating pipes, seating the boots properly and positioning the clamps correctly. Do not use extra clamp force to compensate for a damaged or poorly fitting connection.
Use the applicable vehicle service information and the boot and clamp manufacturer’s installation guidance. If the required tightening specification is unavailable, get it confirmed before installation rather than guessing. A qualified technician can also check the repaired system before the truck returns to loaded use.
Intercooler boots or coolant hoses?
Intercooler boots carry charge air. Radiator hoses carry coolant. Replacing one does not repair a leak in the other system.
Mammoth also offers a 2008–2010 F-250/F-350 6.4L coolant hose kit and a boot-and-radiator-hose combo. Check each product’s own fitment and current availability. The boot kit’s F-450/F-550 fitment does not establish coolant-hose or combo-kit fitment for those trucks.
Frequently asked questions
Does this boot kit fit a 2008–2010 F-450 or F-550?
Yes, with the 6.4L Powerstroke diesel engine. Confirm compatibility separately if the charge-air hardware has been modified.
Do I need a different kit for an early or late 6.4?
Mammoth lists one boot kit for the 2008–2010 6.4L applications above. Do not apply the separate 6.0 Powerstroke build-date split to this kit.
Will new boots fix an underboost warning?
Only if the fault is in the boots or their connections. Diagnose the cause first; pipes, the intercooler and other components may need attention.
Should I replace all the boots?
Inspect the whole set when one fails. The right repair depends on their condition and the cause of the failure. This Mammoth kit supplies four boots and eight clamps for a set replacement.
