Idle Air Control Kit - Haltech Billet

Overview

The Haltech Billet Idle Air Control Kit delivers precise idle management through a robust 2-port billet housing and twin screw-style motors. Essential for EFI conversions and performance builds where OEM idle control has been removed or proves inadequate for modified airflow demands.

Technical Specifications

• Part Number: HT-020305
• Housing Material: CNC machined billet aluminium
• Configuration: 2-port design with dual screw-style motors
• Control Method: Electronic stepper motor control
• Thread Type: Standard automotive fittings

Why You Need This

Idle control becomes critical when you've binned the original throttle body or intake manifold in favour of aftermarket hardware. Standard OEM idle air control valves rarely survive the transition to standalone management, and cheap alternatives create hunting, stalling, and inconsistent idle behaviour that'll drive you mad during tuning sessions. The Haltech billet kit solves this with precision-machined ports and reliable screw-type motors that respond accurately to ECU commands.

We see this particularly on LS swaps into older chassis where the original DBW throttle body gets replaced with a cable-driven unit, SR20 builds running large throttle bodies, and RB engines fitted with aftermarket intake manifolds. The dual-port configuration provides excellent resolution for fine idle control, whilst the billet construction handles underbonnet heat cycles without the warping issues common to cast housings. Twin motors offer redundancy and precise airflow metering essential for consistent idle quality across temperature ranges.

ECU & System Compatibility

Compatible with all Haltech Elite ECUs (550/750/1000/1500/2000/2500) and Nexus R3/R5 units featuring dedicated idle control outputs. The stepper motor configuration integrates directly with Haltech's idle control algorithms for seamless operation.
