FAQ
Is this the gasket between the intake horn and the grid heater?
Yes—this gasket seals the junction between the intake horn (elbow), the grid heater and the intake manifold on 5.9L Cummins engines.
How many do I need?
Most 12-valve (1989–1998) applications use one gasket; most 24-valve (1998.5–2007) applications use two gaskets.
Will it fit all 1989–2007 5.9L Cummins trucks?
Yes, it’s listed for 1989–2007 Dodge/Ram 5.9L Cummins. Always verify for your specific configuration.
What if I also need the lower intake plenum gasket?
That’s a different part (commonly Cummins 3947530). This G32749 addresses the grid-heater/intake-horn junction.
