Regitar USA RMS004 Idle Air Control Valve for MerCruiser MPI Engines

The Regitar USA RMS004 is a replacement idle air control (IAC) valve designed specifically for MerCruiser marine engines equipped with multi-point fuel injection (MPI) systems. This critical component regulates engine idle speed by controlling the amount of air bypassing the throttle plate, ensuring smooth and stable idle performance in all operating conditions.

Key Features:

• Direct replacement for MerCruiser MCM 3.0L MPI engines
• Compatible with V-6 and V-8 MPI engines including 305, 350, and 496 cubic inch displacement models
• Designed for engines equipped with ECM 555 engine control module
• Precision-engineered to OEM specifications for reliable idle control
• Helps maintain proper idle speed and reduce stalling

This idle air controller is an essential component for maintaining optimal engine performance and fuel efficiency. When the original IAC valve fails, symptoms may include rough idle, stalling, or fluctuating idle speed. The RMS004 provides a cost-effective solution to restore proper engine operation.
