241272 - Miller Air Intake Hose for Mitsubishi S4L2 Engine

Protect Your Engine with Genuine Miller Parts

The Miller 241272 Hose, Air Intake is a critical replacement component designed specifically for Miller welding generators equipped with the Mitsubishi S4L2 diesel engine. In the harsh environments where industrial welders operate—construction sites, pipelines, and fabrication yards—dust and grit are constant enemies. The air intake system is your engine's first line of defense, and this molded hose plays a pivotal role in transporting clean, filtered air from the air cleaner assembly to the engine's intake manifold.

Over time, rubber components in a diesel engine are subjected to extreme heat cycles, constant vibration, and exposure to oil or fuel vapors. These conditions can cause intake hoses to become brittle, crack, or lose their elasticity. A compromised intake hose is a serious liability; even a small hairline crack can allow unfiltered air to bypass the air filter. This phenomenon, often called "dusting," introduces abrasive particles directly into the combustion chamber, leading to rapid wear of piston rings, cylinder liners, and valves. Replacing a worn hose with the genuine Miller 241272 ensures a perfect seal and prevents premature engine failure.

This OEM part is manufactured to the exact specifications of the Mitsubishi S4L2 engine layout within Miller equipment. Unlike generic hoses that may kink or require forcing to fit, this pre-molded hose is shaped to navigate the tight confines of the welder's chassis without restricting airflow. Maintaining the proper air-fuel ratio is essential for the efficiency and power output of your diesel welder, and an unobstructed, leak-free intake path is the foundation of that performance. Trust in genuine Miller parts to keep your heavy-duty equipment running reliably for years to come.

Key Benefits of OEM Replacement

Using the correct part number, 241272, guarantees compatibility with your machine's specific configuration. While generic rubber hoses exist, they lack the specific reinforcement and geometry required for the S4L2 application in a Miller housing. Investing in the correct maintenance parts reduces downtime and avoids the catastrophic costs associated with engine rebuilds caused by dirt ingestion.
