Glacier Diesel Power 1998.5–2007 Dodge Ram 5.9L Cummins Pro-Flo Billet Grid Heater Delete Block (98507-PF)
Description
The factory grid heater provides valuable cold-weather starting assistance, but it also places a restriction directly in the intake airflow path.
For modified trucks and applications where a grid heater is no longer required, the Glacier Diesel Power Pro-Flo Grid Heater Delete Block provides a clean, high-flow replacement designed specifically for 1998.5–2007 Dodge Ram 5.9L Cummins engines.
Machined from solid billet aluminum, the Pro-Flo replaces the restrictive factory grid heater assembly with an open, unrestricted intake passage. When airflow matters and you're trying to get every available CFM into your Cummins, removing unnecessary restriction from the intake system is another piece of the puzzle.
Unlike thin delete plates, the Pro-Flo is a full-height billet riser designed to replace the factory grid heater block while maintaining the intake connection between the intake manifold and charge-air system.
Simple, strong, and purpose-built—the Pro-Flo is an excellent addition to modified 5.9L Cummins applications where maximum airflow is the priority.

Why Remove the Factory Grid Heater?
The factory grid heater sits directly in the intake airflow path.
Its job is important when additional intake heat is needed for cold-weather starting, but on modified trucks operating in climates where a grid heater isn't necessary, that same component becomes another restriction incoming air has to pass through.
The Pro-Flo removes that restriction.
Instead of forcing incoming air through the factory heating element, the billet Pro-Flo provides an open passage between the charge-air system and intake manifold.
For performance applications where every available CFM counts, reducing restrictions throughout the intake system helps the engine take better advantage of upgraded turbochargers, increased fueling, and other airflow modifications.
Solid Billet Aluminum Construction
The Pro-Flo isn't a thin plate designed simply to cover the opening left behind when the factory grid heater is removed.
It's a solid billet aluminum riser designed specifically to replace the factory grid heater block.
The full-height design provides the physical connection required by the intake system while eliminating the restrictive heating element from inside the airflow path.
It's a simple component, but it serves an important purpose: maintain the required intake geometry without putting an unnecessary restriction back into the system.
Built for Modified Cummins Trucks
The Pro-Flo makes the most sense on trucks where airflow is the priority and cold-weather grid heater operation isn't required.
It's an excellent supporting modification for trucks equipped with:
- Larger turbochargers
- Increased fueling
- Larger injectors
- High-flow intake manifolds
- Upgraded intercooler piping
- Competition-oriented engine combinations
- Other performance airflow upgrades
It can also be used on less-modified trucks when the owner simply doesn't require the factory grid heater, but customers should understand that installing the Pro-Flo eliminates the factory intake heating function.
Glacier Tech Tip
A high-flow intake system is only as good as the restrictions that remain in front of it.
Installing a larger intake manifold or improving plenum airflow while leaving a restrictive component directly in the airflow path can limit the benefit of those upgrades.
The Pro-Flo provides a simple way to remove the factory grid heater restriction on 1998.5–2007 5.9L Cummins applications where intake heating is no longer required.
For customers building a more complete Glacier Diesel Power intake system, the Pro-Flo can be paired with the appropriate Air-Boss Intake Plenum and high-flow intake manifold for your generation of 5.9L Cummins.
Why Choose Glacier Diesel Power?
Sometimes the best performance component doesn't need to be complicated.
The Pro-Flo was designed to do one job: replace the restrictive factory grid heater block with a strong, unrestricted billet intake passage.
No gimmicks. No unnecessary complexity. Just a purpose-built component designed around the 5.9L Cummins intake system.
Solid billet aluminum. Maximum airflow. Engineered by Glacier Diesel Power.
