Product Description
CUMMINS 3923216 OEM LONG INTAKE HORN BOLT (HEX FLANGE HEAD CAP SCREW) – RAM 5.9L 12V (1994–1998)
The genuine CUMMINS 3923216 OEM long intake horn bolt is the factory-correct hardware used to secure the intake horn to the intake plate on the 5.9L 12-valve Cummins. This OEM hex flange head cap screw provides proper clamping force, correct thread engagement, and reliable sealing — essential for preventing boost leaks and maintaining the structural integrity of the intake assembly.
Over time, factory bolts may become rusted, stretched, or rounded, especially in high-mileage work trucks. Replacing them with new Cummins OEM hardware ensures proper torque retention and a trouble-free seal between the intake horn and manifold. This bolt is manufactured to Cummins specifications to handle vibration, heat, and boost pressure without loosening or fatigue.
Pair this bolt with other authentic Cummins hardware — such as the matching short intake horn bolts and sealing components — to restore your intake system to factory-new condition.

Frequently Asked Questions
IS THIS THE CORRECT LONG BOLT FOR THE 12-VALVE INTAKE HORN?
Yes — Cummins 3923216 is the OEM long bolt used on 1994–1998 5.9L 12-valve engines to secure the intake horn. Always verify by VIN/ESN for accuracy.
DO I NEED TO REPLACE ALL THE INTAKE BOLTS AT ONCE?
It is recommended. Replacing only one bolt may lead to uneven clamping or mismatched hardware. Consider pairing it with the OEM short bolt CUMMINS 3930910.
WILL THIS WORK WITH AFTERMARKET INTAKE HORNS?
Many aftermarket horns mimic OE hardware requirements, but not all. Check your intake horn manufacturer’s specs for bolt length and thread pitch.
IS THIS A GENUINE CUMMINS BOLT?
Yes. CPP Diesel supplies authentic Cummins OEM hardware, not generic substitutes.
WHAT SIZE SOCKET DO I NEED?
Most OE Cummins intake horn hardware uses a standard hex head. Consult your service manual for torque values and tool sizes.
