Throttle Body - 80mm Dodge Hemi 5.7/6.1/6.4L

The BBK Performance Throttle Body 80mm for Dodge Hemi 5.7/6.1/6.4L engines is a cable-driven intake upgrade designed to increase airflow and throttle response on Gen III Hemi platforms. This 80-millimeter single-blade throttle body replaces the restrictive stock unit, delivering measurable improvements in fuel economy calibration and wide-open-throttle acceleration. Built from aircraft-grade aluminum with a natural finish, the BBK1791 mounts directly to the stock flange without requiring custom fabrication or adapter plates.

The 80mm bore diameter offers a significant advantage over smaller throttle bodies by reducing intake restriction while maintaining precise air-metering capability through the single-blade design. This specification is critical for Hemi applications because the Gen III engine family responds well to increased volumetric efficiency—the larger diameter allows the fuel injection system to deliver finer control without hunting or idle quality loss. The cable-driven mechanism retains full compatibility with factory accelerator linkage, eliminating the need for expensive standalone fuel management systems. Aluminum construction provides corrosion resistance while keeping weight to a minimum (2.7 lbs).

This throttle body is engineered for street-driven Dodge Hemi trucks and performance vehicles where owners seek bolt-on intake upgrades without ECU tuning complications. It suits daily drivers and weekend performance builds alike—situations where increased breathing capacity directly improves throttle tip-in feel and mid-range power delivery. The stock-flange mounting ensures drop-in installation on 5.7L, 6.1L, and 6.4L Hemi variants without modification. BBK Performance's reputation in the Mopar aftermarket rest on precision engineering and real-world dyno validation, making this a trusted choice for Hemi platform upgrades that demand reliability alongside performance gains.
