Universal 4-Barrel EFI Billet Aluminum Throttle Body - Natural

This 6061-T6 billet aluminum throttle body is designed for universal 4150-flange EFI applications, supporting responsive airflow control and clean fitment on properly matched intake setups. At 1.75" per bore across 4 bores, it's rated for approximately 1,000 CFM, sized to match airflow capacity with your intake manifold and engine combination. Throttle actuation is cable-driven — this is not a drive-by-wire throttle body, so confirm your setup uses cable actuation before ordering. It has the correct geometry for the 700R4 kickdown. It accepts a standard 5-1/8" air cleaner flange. Gasket and mounting hardware are included; the IAC motor, TPS, and MAP sensor are not included, since these vary by ECU and tuning setup. Confirm intake bore size, throttle control style, sensor configuration, and tuning requirements before installation — tuning may be required after installation depending on your specific EFI setup. Applications Fits manifolds with a standard 4150-style square-bore flange and standard bolt spacing. Common use cases include street performance applications, restoration projects, and custom EFI conversions. Installation Cable-actuated (700R4-style provision), 5-1/8" air cleaner flange. Gasket and mounting hardware included. IAC motor, TPS, and MAP sensor not included — see compatible part numbers below. Confirm throttle body bore size, 4150 flange compatibility, cable bracket needs, and hood clearance before final assembly.
