Stop choking your EFI 5.0.

If you’re running a Holley EFI system or a modern standalone ECU on a Fox Body Mustang, you already know the struggle: trying to get the factory Ford IAC to play nice, or settling for restrictive aftermarket GM adapters that simply can't feed the engine enough air.

Meet the ultimate fix. Our new LS Idle Air Control (IAC) Adapter for Fox Body Mustangs lets you seamlessly run a high-performing LS-style IAC motor on your Ford throttle body.

The big difference? Flow. ?️ While standard options on the market restrict your idle path, our internal geometry flows twice as much air. No more surging, no more dipping, and no more fighting to get a stable, crisp idle—even on aggressive, large-displacement, or heavily cammed combinations.

2x the Airflow of competing designs.
Billet aluminum construction.
Perfect for custom EFI setups (Holley, Haltech, Link, etc.).
Fixes radical cam and low-vacuum idle issues for good.

This product is intended for use with aftermarket EFI systems. This will not work with the original EFI that came with your Mustang.
