Air Intake Hose Pipe for Mercedes-Benz OEM 276 090 2537

Product Overview

This Air Intake Hose is supplied for Mercedes-Benz applications and is catalogued against OEM 276 090 253. Matching starts from the reference rather than from a picture, which is what keeps a container of parts out of the returns pile. Because the part carries filtered air from the airbox to the turbocharger inlet or throttle body, a worn one rarely fails cleanly — expect cracks around moulded sensor ports and hardened cuffs that no longer seal on the airbox spigot long before it separates, with unmetered air downstream of the mass airflow sensor, a rough idle and airflow fault codes as the first complaint over the counter. Hunan Woojin Autoparts supplies it from a cooling-system range of more than 4000 types covering German, French, Japanese, American and Korean vehicles.

Key Benefits

• Mixed pallets instead of single lines — A cooling-system range of more than 4000 types means a slow-moving line can travel with fast movers instead of being ordered on its own.
• Tooling route for obsolete references — Where the reference is out of production, we develop the mould from the sample you supply rather than turning the enquiry away.
• Checked on the features that matter — Inspection concentrates on the bellows pitch, the connector geometry and the sensor port position — the dimensions that put a part back in the box if they are wrong.
• Matched to how the part actually fails — Cracks around moulded sensor ports and hardened cuffs that no longer seal on the airbox spigot are the reasons this reference is bought, so those are the features checked before packing.

Application Scenarios

Mixed container for a distributor

A quarterly container is filled across families — intake, charge air, coolant and thermostat lines — to a single packing list. This reference, 276 090 253, is bought for exactly that situation on Mercedes-Benz vehicles.

Scheduled cooling-system overhaul

The vehicle is in for a coolant leak and the workshop replaces the whole branch at once rather than chasing the next failure in a month. For 276 090 253 the practical step is confirming the bellows pitch, the connector geometry and the sensor port position before the order is placed.

Warranty-expired fleet maintenance

A fleet past dealer coverage moves to independent supply and needs the same reference coverage at a working price. This reference, 276 090 253, is bought for exactly that situation on Mercedes-Benz vehicles.

Who It Is For

• Exporters and consolidators — shipping mixed cooling-system pallets into Europe, the Middle East and South America. 276 090 253 earns its shelf space through repeat demand on Mercedes-Benz platforms.
• Aftermarket distributors — stocking cooling-system lines for Mercedes-Benz across a regional network and needing a reference-accurate catalogue behind the shelf. What they need from 276 090 253 is that it fits the Mercedes-Benz on the ramp today.
• Workshop and fast-fit chains — replacing air intake hoses on Mercedes-Benz daily and judging a supplier on whether the part fits first time. They order 276 090 253 by the carton and reorder against the same number.

Problems It Solves

Unclear compound

The steel helix is what stops the duct collapsing, so any duct that has been crushed in transit should be rejected on arrival. That is why 276 090 253 carries its full cross-reference set on this page.

Reference mismatch

Visually identical parts carry different connector geometry between model years. Quoting OEM 276 090 253 fixes the identity before money moves. That is why 276 090 253 carries its full cross-reference set on this page.

Split ordering

Sourcing one hose from one supplier and the matching flange from another doubles the freight and the paperwork for the same repair. That is why 276 090 253 carries its full cross-reference set on this page.

Technical Features

The part serves the air intake tract and carries filtered air from the airbox to the turbocharger inlet or throttle body. It is moulded in Non-woven fabric with steel reinforcement and PP connector / TEEE, chosen because a non-woven wall over a steel helix keeps the duct open against intake depression while damping induction noise, with moulded PP or TEEE ends carrying the sealing geometry.

Specified on large-diameter ducts where noise damping and collapse resistance both matter. The steel helix is what stops the duct collapsing, so any duct that has been crushed in transit should be rejected on arrival.

Specifications

Values marked TBC are not stated on the source catalogue. They are confirmed in writing on the quotation rather than estimated here.

Comparison With the Alternatives

Use Guide

1. Confirm the reference

   Match OEM 276 090 253 against the number on the part you removed. Do not match on outline alone.

2. Check the interfaces

   Compare the bellows pitch, the connector geometry and the sensor port position before the vehicle is stripped further.

3. Inspect on arrival

   Look for transit damage on sealing faces and connectors. The steel helix is what stops the duct collapsing, so any duct that has been crushed in transit should be rejected on arrival.

4. Fit with the original clamp style

   Reuse the clamp type the Mercedes-Benz platform was designed around, and fit any seal or O-ring supplied with 276 090 253 rather than carrying the old one over.

5. Pressure check before handover

   Refill, bleed the circuit and check for splits along the convolutions at working temperature before the vehicle leaves.
