98-07 Dodge 5.9L Cummins Diesel S&B CNC Heater Block Delete

For those living in warm climates where cold starts are not an issue, the OE heater grid can be replaced with S&B’s Heater Block Delete, which will provide a 30.91% improvement in airflow. S&B's Heater Block Delete is CNC Machined from 6061 – T6 Aluminum and is built for extreme performance. Because of its simple, trouble free installation, it's a breeze to switch back to your stock heater grid, for engine starting during the cold winter months. The S&B heater block delete increases airflow by 30.91% over the highly restrictive OEM heater grid. More airflow equals better performance. For even greater airflow, improved turbo spool, and to help lower EGTs, make sure to stack your heater block delete with their Premium Intake Elbow.


If you drive in an area that drops below 30 °F, you should not install this product during these conditions, as you will need the OE heater grid in order to start your truck. The OE heater grid is used if the ECM reads intake manifold air temperatures below 19 °C (66 °F) to help with long cranking starts. The air heater elements are used to heat incoming air to the intake manifold. This is a necessary feature for those living in colder climates; however, the heater grid does restrict airflow.
