The Multiquip M1374000003 Air Cleaner Pipe is a genuine OEM component designed for DCA20SPXU4F and DCA25SSIU4F series diesel powered generators. As a direct OEM replacement, this air cleaner pipe is manufactured to the same specifications as the original part, ensuring a proper connection between the air intake and the engine's filtration system. Fitment is confirmed for the DCA20SPXU4F, DCA20SPXU4F SERVPRO, and DCA25SSIU4F models, making it a straightforward swap with no guesswork on compatibility.
Key Features
- Genuine OEM Construction — Correct wall thickness and connector geometry engineered specifically for the DCA-series intake path, not a generic substitute.
- Direct-Connect Fit — Seats precisely at the air cleaner housing outlet and routes to the engine intake as originally assembled, maintaining a sealed, leak-free airflow path.
- Confirmed Fitment — Verified for DCA20SPXU4F, DCA20SPXU4F SERVPRO, and DCA25SSIU4F diesel powered generators.
- Protects Engine Air Quality — A correctly sealed air cleaner pipe prevents unfiltered air from bypassing the air cleaner element, which directly protects internal engine components from contaminant ingestion.
- Fuel System Integrity — Maintaining proper air intake volume and pressure supports accurate air-to-fuel ratios, helping the generator sustain stable output under load.
The air cleaner pipe channels filtered air from the air cleaner assembly into the engine intake, forming a critical sealed link in the air induction system. If this pipe cracks, loosens, or deteriorates, unfiltered air can enter the engine downstream of the air cleaner element, accelerating wear on cylinder walls, pistons, and rings. On a generator expected to run under sustained load, a compromised air cleaner pipe can also cause rough running, black exhaust, or poor fuel economy as the engine struggles to maintain the correct air-fuel mixture.
