Description
Fits: AEM 21-8104 intake systems on 2003–2006 Ford F-250/F-350 6.0L diesel; one specified service coupling, not an original-equipment hose.
Replace the 5-400 hose identified in the 21-8104 instruction BOM without substituting a different length or diameter. The current AEM specification is reinforced multi-ply silicone.
Product details
- 4-inch tube connection; 3-inch overall length.
- Black exterior; one coupler per package, with a 90-day manufacturer warranty.
- No clamps are listed in the one-coupler package; use the matching kit’s specified sound clamps.
What is included
One exact AEM coupler/reducer only. The intake kit, filter, tubes and mounting hardware are not included.
Installation and service
Match the installed kit number and hose dimensions before service. Refit the specified clamps and inspect all joints for a secure, leak-free seal. This catalog entry validates the named intake service location only; it does not assert a charge-air/boost-hose rating.
Application and emissions notes
Replacement/service part only. Match the installed AEM kit number and retain its required adapters, sensors and emissions equipment. This part is not an intake conversion and does not grant emissions approval to any installation; local restrictions still apply.
