Killshot II 4bbl EFI Polished

The Killshot II 4bbl EFI Polished throttle body from ACES Fuel Injection represents a modern upgrade path for enthusiasts seeking refined engine control and visual appeal on the engine bay shelf. Built for classic and street performance applications where carburetor conversion to electronic fuel injection demands a quality, aesthetically finished component, this throttle body serves as the command center for fuel and air metering in EFI systems. Whether you're retrofitting a vintage muscle car, restomod, or street rod with contemporary engine management, the Killshot II bridges the gap between reliable engine operation and the polished appearance that separates a show-quality build from a functional one.

This 4-barrel EFI throttle body integrates a four-port fuel delivery design optimized for V8 and high-displacement engines requiring balanced airflow distribution across all cylinders. The polished aluminum finish not only delivers the professional appearance demanded by concours-level builds but also ensures corrosion resistance and durability under hood heat and vibration. At 16.1 pounds and dimensioned at 14.8 x 8.4 x 23.8 inches, the Killshot II mounts to compatible EFI manifolds and intake plenums, utilizing the proven four-barrel bore configuration that maintains proper throttle response and fuel atomization across the RPM range. The precision-engineered internals and throttle plate geometry ensure smooth, linear throttle response without flat spots or hesitation—critical for street-driven vehicles where daily drivability matters as much as performance.

Hot rod builders, classic car restorers, and street performance enthusiasts will find the Killshot II essential when transitioning from mechanical carburetion to EFI on big-block and small-block V8 platforms. The polished finish makes this component a focal point for engine bay photography and car show judging, while its engineered internals ensure that fuel injection tuning remains responsive and reliable. Proper installation requires alignment with your EFI management system's fuel rail configuration and vacuum hose routing; verify throttle body bore diameter compatibility with your intake manifold adapter before ordering. This is a core component for anyone committed to marrying classic automotive aesthetics with modern fuel injection dependability.
