The genuine CUMMINS 3919864 OEM short intake horn bolt restores the factory-correct fastener setup on the 5.9L 12-valve Cummins intake horn.

Whether you're refreshing worn hardware or reinstalling a factory horn, the OEM 3919864 fastener delivers exact fitment and material durability engineered for long-term reliability.
Because intake horn hardware commonly corrodes or becomes rounded over time, replacing it with authentic Cummins hardware ensures the correct clamp load and prevents stripped threads or sealing issues.

Frequently Asked Questions
IS THIS THE CORRECT BOLT FOR MY 12-VALVE INTAKE HORN?
Yes. CUMMINS 3919864 is the short intake horn bolt used on 1994–1998 5.9L 12-valve engines. Always verify with your VIN/ESN for complete accuracy.
HOW MANY OF THESE BOLTS DOES MY INTAKE HORN USE?
Most OE 12-valve intake horn setups use a combination of short and long bolts. This part number represents the short bolt only. Inspect your existing hardware before ordering.
CAN I USE AFTERMARKET HARDWARE INSTEAD?
Aftermarket bolts often vary in hardness, thread pitch quality, and shoulder profile. We recommend genuine Cummins hardware to ensure proper sealing and prevent intake leaks.

It is highly recommended to replace the gasket anytime the intake horn is removed. This prevents boost leaks and ensures proper sealing.
IS THIS BOLT TORQUE-SPECIFIC?
