Part Number: 76-1005

• Provides a 30.91% improvement in airflow
• CNC Machined from 6061-T6 Aluminum
• For extreme performance
• Ability to easily switch back to stock heater grid (for starting in cold months)

• 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.
