35-8M2001030 - Mercury MerCruiser Filter Throttle Body 350 377 MAG MPI Horizon Alpha Bravo 4.3L 5.0L 5.7L 6.2L MPI Alpha Bravo Horizon

A smooth-running engine starts with clean airflow, and that’s exactly what the Mercury MerCruiser IAC Filter (35-8M2001030) is designed to protect. This small but essential component keeps dust, debris, and contaminants from reaching the idle air control (IAC) valve, ensuring steady idling and efficient throttle response. Over time, clogged or dirty filters can cause rough idling, inconsistent performance, and even unnecessary strain on the engine. Replacing this filter as part of regular maintenance helps prevent these issues and keeps your MerCruiser running at peak efficiency.

Why It Matters:

• Protects the Idle Air Control System – Keeps contaminants out, ensuring a smooth and stable idle.
• Built for Marine Environments – Designed to handle salt, moisture, and temperature fluctuations without breaking down.
• Essential for Key MerCruiser Models – Compatible with 350 MAG MPI Horizon Alpha/Bravo, 4.3L, 5.0L, 5.7L, and 6.2L MPI Alpha/Bravo Horizon engines.

A reliable engine isn’t just about power—it’s about precision. Keeping the IAC system clean can prevent performance issues before they start. If you’re noticing erratic idling or hesitation, a fresh IAC filter might be the fix your engine needs. Simple, effective, and built to last, this OEM part keeps you on the water without the hassle.
