FASWORX Idle Air Control (IAC) Valve 805224A1 for MerCruiser & Volvo Penta GM V6 V8 EFI Engines – Replaces 805224 – MCM/MIE 305 350 454 502

This idle air control valve is a direct replacement component used on GM-based marine EFI engines to manage idle speed by controlling bypass air around the throttle plate. It is commonly found on MerCruiser and Volvo Penta gasoline engines equipped with electronic fuel injection where stable idle and cold-start behavior depend on proper IAC operation. The valve replaces MerCruiser part number 805224A1 and supersedes earlier 805224 catalog listings when specified by the engine manufacturer. It is typically identified during diagnosis of unstable idle, stalling at low RPM, or fault codes related to idle air control on GM-based marine engine platforms. Designed as an OEM-style aftermarket service part, this FASWORX idle air control valve is intended for installers and experienced owners servicing MCM and MIE GM V-6 and V-8 EFI engines, including widely used 305, 350, 454, and 502 CID configurations.

• Direct replacement idle air control valve designed to regulate engine idle speed on GM-based marine EFI systems used in MerCruiser and Volvo Penta applications.
• Replaces OEM part number 805224A1 and supersedes earlier 805224 versions where specified in marine engine catalogs.
