Product Description
INDUSTRIAL INJECTION PDM-08002 GRID HEATER SPACER is a proven bolt-in upgrade for the 1994–2007 Dodge/Ram 2500/3500 5.9L Cummins. By replacing the restrictive OE grid heater stack height with a precision spacer, it helps smooth the intake path for improved airflow and crisp throttle response — an easy add-on any time the intake horn is off.
- Direct fit for 5.9L Cummins (1994–2007) — 12V, early 24V, and common-rail years
- Restores/open ups plenum height to reduce turbulence at the intake horn
- Simple install during intake horn service
Fitment
Designed for 1994–2007 Dodge/Ram 2500/3500 5.9L Cummins intake manifold between the grid heater and intake horn/elbow.
What’s Included
- (1) Industrial Injection PDM-08002 grid heater spacer

FAQ
Will this spacer cause hard cold starts?No. This part retains your existing stack height and does not modify ECU control. It simply optimizes the airflow path under the horn. For extreme cold operation, inspect your starting system and consider winter prep best practices.
Do I need new gaskets?Yes — you should replace both intake/grid gaskets whenever the horn is removed. We recommend two of Cummins 3969988.
What other parts pair well with this?High-flow intake horns and boost tube kits complement the spacer by further reducing restriction. See our recommended parts above for direct CPP links.
