Frequently Asked Questions (FAQ)

Why do I need to replace the factory grid heater on my 6.7L Cummins? The factory OEM grid heater is notorious for a fatal design flaw: the "grid heater nut" can degrade, break off, and fall directly into your engine cylinders. This results in catastrophic engine failure. The Fleece Performance Intake and Grid Heater Kit eliminates this risk entirely while improving airflow.

Will my truck still start in extreme cold weather with this kit? Yes! The base kit includes a high-flow 700W coil heater that provides reliable starting power down to 23°F (-5°C). If you live in a colder climate, we recommend pairing this with the Fleece Cold Weather Upgrade Kit (FPE-CUMM-IAH-X2) for proven starting reliability down to -31°F (-35°C).

Do I need to buy custom high-pressure fuel lines for this installation? No. Unlike some competing kits, the Fleece Performance intake horn is designed to allow you to reuse your factory (OE) high-pressure fuel lines, or install standard aftermarket replacements, saving you time and money.

Does this kit fit 6.7L Cummins trucks with dual alternators? Yes, it fits dual alternator equipped trucks. However, please note that due to clearance limitations with the alternator bracket, only the rear heater port location can be utilized.
