Some Fleece Fun on this fine Tuesday for this 2016 6.7L Cummins!

Eliminate your risk of engine damage from the OE style grid heater nut failure with this Fleece intake manifold and grid heater upgrade!

This intake horn and high flow intake plate are direct replacements that increase engine airflow and replace the factory style grid heater with a robust coil heating element!

Protect your investment!!
