Fleece Performance Engineering just dropped big news for Ram owners and the diesel performance community: an all-new Intake Horn and Grid Heater Upgrade for the 2007.5–2024 6.7-liter Cummins. Set to hit the market in the first quarter of 2026, this kit targets one of the platform’s most notorious failure points, delivering cleaner airflow, improved cold-weather performance, and a smart, no-compromise installation.
For years, 6.7-liter Cummins owners have lived with the OEM grid heater’s reputation for potential failure—and the catastrophic engine damage that can follow if fragments are ingested. Fleece’s new system eliminates that risk by replacing the failure-prone factory component with a high-integrity, engineered solution built to the company’s well-known standards.
Beyond safety, the redesigned intake horn provides improved overall airflow, supporting both stock and modified applications. Because Fleece engineered this upgrade to retain all factory high-pressure fuel lines, owners don’t have to wrestle with rerouting, deleting, or changing key under-hood components. It’s a clean bolt-on solution that fits all 2007.5–2024 models, including cab-and-chassis trucks. This is a massive win for workhorse owners and commercial fleets.
Cold-weather users get another major benefit: the system has been validated down to –30 degrees Celsius, ensuring reliable starting and drivability even in the harshest winter climates. With an MSRP of $628.95, Fleece positions the new kit as an accessible, enthusiast-grade protection and performance upgrade for owners of 6.7-liter Cummins engines.
Fleece Performance’s Intake Horn and Grid Heater Upgrade makes its first public appearance this week at the PRI Show in Indianapolis, booth #3467. For Cummins owners seeking to protect their engines, clean the air path, and install with confidence, this new kit marks yet another innovation from one of diesel’s most trusted names.
