1989-2007 Cummins Genuine Intake Heater Gasket 3969988

Seal up the intake in your engine with the Cummins 3969988 Genuine Intake Heater Grid Gasket. The heater grid comes off during a lot of repairs such as fuel injector removal. This was typically a graphite gasket from the factory with one installed on top and bottom of the grid heater, so you'll need two of these. It's good insurance to replace them anytime the intake elbow or grid heater comes off to avoid any potential boost leaks when sealing everything back up.
