One of the proven methods for getting more power from your diesel is to increase the airflow through the intake. The 5.9 Cummins High Flow Grid Heater from Sinister Diesel dramatically improves the intake airflow in your truck. By removing the unused and obstructing stock unit, the Sinister Diesel High Flow Grid Heater creates a much clearer and smoother intake airflow resulting in noticeable performance gains. And if your truck pulls double-duty in the frigid winter, the Sinister Diesel High Flow Grid Heater can be easily swapped out and replaced with the factory grid heater for easier starting when the ambient temperature drops below freezing. Installation takes less than 20 minutes and ensures a factory fit and a proper seal to eliminate boost leaks.
