About This Product: The Problem vs. The Solution

The Problem: The 6.7L Cummins engine suffers from a flaw in the electrical connection to the intake grid heater. When powering the heater, 200 amps pass through a small bolt and nut inside the intake. Over time, this connection deteriorates, arcs, and eventually breaks off. If this nut drops into the engine, it causes extensive damage to the piston, head, and valves.

The Solution: Current market solutions are often costly, reduce heat performance in cold climates, or require tuning. This Upgrade Kit fixes the flawed circuit by permanently eliminating the problematic internal bolts and nuts. It is cost-effective, easy to install, and keeps your truck working exactly as the factory intended—just safer.
