High Idle Kit 05-16 Ford 6.0/6.4/6.7L

The BD DIESEL High Idle Kit for 05–16 Ford 6.0L, 6.4L, and 6.7L diesel engines is a complete wiring harness and switch assembly designed to raise engine idle speed for improved cold-start performance and reduced thermal stress during regeneration cycles. This kit addresses a common limitation in stock Ford Power Stroke engines, where idle temperatures can drop below optimal operating thresholds during extended idle periods or parked regeneration events.

The kit includes a high-idle switch module and pre-assembled wiring harness engineered for direct integration into Ford's existing engine control architecture. By allowing manual elevation of idle RPM from the driver's seat, the system maintains exhaust gas temperatures necessary for proper diesel particulate filter regeneration without forcing a full engine restart cycle. The harness assembly is routed through OEM connection points, eliminating the need for engine bay modifications while ensuring reliable signal transmission to the vehicle's ECU.

This high-idle kit is ideal for fleet operators, towing professionals, and owners of 6.0L and 6.4L engines who frequently park with the engine running or operate in extended idle scenarios common to service work, livestock transport, or construction applications. The 6.7L generation benefits from refined regeneration controls that work seamlessly with the high-idle function. Compact at 0.43 lbs with dimensions of 6.85 x 2 x 10.1 inches, the kit stores easily and integrates without visible cabin intrusion when properly installed.

BD Diesel has established itself as an authoritative supplier of Ford Power Stroke performance and reliability upgrades. The high-idle function represents a straightforward efficiency gain: maintaining steady idle temperature reduces EGR cooler scale buildup, lowers fuel dilution in the crankcase during extended parked regeneration, and extends intervals between forced regens on newer models. This kit is particularly valuable for owners of the 6.0L generation, where thermal management directly impacts long-term engine durability.
