aFe 59-00003 supplies the specified flexible injection-molded polyurethane connection and listed clamp hardware. Match the actual installed assembly before ordering.
Key Features
- 4 in internal diameter; 4 in length; hump profile
- Flexible injection-molded polyurethane.
- Exact kit contents are listed below; this component kit is not a complete intake.
Fitment
| Application | Required checks |
|---|---|
| Specification-matched intake connection | Connect specification-matched 4-inch intake tubes using the 4-inch-long hump coupling. Match the full sealing engagement, clearance and movement required by the installed assembly. Common use on aFe intakes does not establish compatibility with every intake or a vehicle-wide application. |

Frequently Asked Questions
Which connection does this coupling require?Connect specification-matched 4-inch intake tubes using the 4-inch-long hump coupling. Match the full sealing engagement, clearance and movement required by the installed assembly. Common use on aFe intakes does not establish compatibility with every intake or a vehicle-wide application.
What material is specified?Flexible injection-molded polyurethane. Do not select a replacement by assuming every flexible intake coupling uses the same material.
What dimensions and geometry should I check?4 in internal diameter; 4 in length; hump profile Match full tube engagement and clearance as well as nominal diameter.
Which hardware is supplied?One 4-inch-ID x 4-inch-long hump coupling and two stainless-steel #072 worm clamps. No tube, filter or complete intake is itemized.
Are numeric pressure or temperature ratings supplied?The exact current page does not provide numeric operating pressure or temperature ratings. Its general engine-compartment or flexibility description does not certify suitability for every pressurized or fluid-system use.
What clamp torque should I use?No numeric clamp torque is stated on this exact page. Follow the applicable installed intake and connection instructions rather than borrowing a torque from unrelated clamps.
Why does the coupling have a hump?The manufacturer describes flexibility for expansion, movement and vibration. Match the actual tube alignment and required engagement; that function does not supply a pressure rating or approve unlimited movement.
Does this kit replace the complete intake?No. The kit contents are the coupling and listed hardware. A complete intake, housing, air filter, sensor or calibration is not supplied unless specifically itemized; this listing does not certify vehicle power gains.
Installation Instructions
Confirm aFe 59-00003 and the actual installed intake connection. Compare all diameters, length, shape, seal engagement and clearance before fitting the coupling and listed clamps. Follow that assembly’s instructions for placement, tightening and checks. This exact kit page does not supply a numeric clamp torque or complete vehicle-specific intake procedure.
