Holley 112-588 MPFI Throttle Body, 1000 CFM, Polished Aluminum

The Holley 112-588 MPFI Throttle Body is designed for applications requiring controlled airflow through a 4-barrel, square-bore configuration. With a 1000 CFM airflow rating, this throttle body provides a high-capacity foundation for compatible fuel-injection systems and performance-oriented engine builds.

Constructed from aluminum and finished with a polished surface, the unit combines functional design with a clean appearance. Its square-bore layout supports installation where this configuration is required, while the universal application description allows it to be considered for a range of setups when properly matched to the vehicle and engine system.

GM IAC and TPS sensors are included with the throttle body, helping provide the components specified for its electronic throttle-management configuration. Review the requirements of your application before installation to confirm that the 4-barrel square-bore design, sensor arrangement, and 1000 CFM capacity are appropriate.

This Holley throttle body is sold individually and offers a polished aluminum construction for builders seeking a universal MPFI throttle-body solution. The product data identifies it as not air restricted and not truck-freight only.
