LS-Style IACV To Ka24de Conversion Kit

Upgrade your KA24DE by replacing the expensive OEM IACV with a more affordable and widely available LS-style idle air control valve. This kit is designed to simplify your setup while improving serviceability and parts availability.

It allows you to eliminate the factory IACV and run a 5/8" ID hose directly to your charge pipe or intake. For improved routing and cleaner installation, the hose inlet has been relocated to the top of the valve rather than the OEM bottom position (see product photos).

What’s Included:

• IACV adapter
• Laser-cut mounting hardware
• 1/4" to 5/8" barb fitting
• 90° 1/4" NPT fitting
• LS-style IACV

Important Notes:

• Wiring pigtail for the LS IACV is not included and must be sourced separately
• A standalone ECU is required for proper operation
• This is a stepper motor valve and requires a 4-wire setup
