Holley EFI 112-588 Universal 1000 CFM 4-Barrel Throttle Body

The Holley EFI 112-588 is a high-performance universal throttle body designed for high-horsepower fuel injection applications. With a 1000 CFM flow rating and square bore mounting pattern, this throttle body provides the airflow capacity needed for big cubic inch engines while maintaining compatibility with a wide range of intake manifolds.

Key Features:

• 1000 CFM airflow capacity for high-horsepower engine applications
• Integrated throttle position sensor (TPS), idle air control (IAC), and air temperature sensor
• High-flow IAC passages engineered for larger displacement engines to ensure stable idle performance
• Tumble polished finish for a premium appearance
• High-quality die-cast aluminum construction offers excellent strength-to-weight ratio
• 1.75-inch throttle plates mounted on PTFE-coated throttle shafts for increased airflow and smooth operation
• Standard square bore mounting pattern fits most common intake manifolds
• Integrated GM 700R4 transmission kickdown location eliminates need for adapters
• Ford transmission kickdown lever provision for use with Ford automatic transmissions
• Multiple vacuum ports: one timed spark port, two 3/8-inch ports, and two 3/16-inch full manifold vacuum ports
• CFD computer-modeled air entry design maximizes air velocity and flow characteristics

This throttle body is an excellent choice for builders seeking a reliable, high-flow solution for street or racing EFI systems. The integrated sensors simplify installation and wiring, while the transmission kickdown provisions provide compatibility with popular automatic transmissions.
