Air Intake Hose Pipe for Mercedes-Benz OEM 2720903682 (WJ-H1142)

Product Overview

Air Intake Hose Pipe for Mercedes-Benz OEM 2720903682 (WJ-H1142) covers the air intake tract on Mercedes-Benz applications. The reference set on file is OEM 2710900982 and 2720903682, which is the figure to quote when you send an enquiry. The air intake tract gives this part a hard life: heat soak, vibration and pressure cycling. Typical end-of-life signs are cracks around moulded sensor ports and hardened cuffs that no longer seal on the airbox spigot, which reach the workshop as unmetered air downstream of the mass airflow sensor, a rough idle and airflow fault codes. We hold it as part of a cooling-system range of more than 4000 types built for the independent aftermarket in Europe, the Middle East and South America.

Key Benefits

• Aftermarket buyers, not one-off retail — Pricing and packing are set up for distributors and workshop chains buying by the carton, not for single-piece retail.
• Ordered by reference not by photo — The listing carries OEM 2710900982 and 2720903682. You quote the number, we confirm against the same number, and the part that ships is the one on the invoice.
• 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.
• Sample-based production for parts not yet listed — Send the old part or a drawing and we quote from the sample, including mould development where no tool exists.

Application Scenarios

Breakdown repair

The vehicle is off the road and the part has to be right the first time, which makes the reference match the whole decision. This reference, 2710900982, is bought for exactly that situation on Mercedes-Benz vehicles.

Rebuild of an obsolete platform

The original reference is no longer produced, so the part is made from a supplied sample. This reference, 2710900982, is bought for exactly that situation on Mercedes-Benz vehicles.

Mixed container for a distributor

A quarterly container is filled across families — intake, charge air, coolant and thermostat lines — to a single packing list. On this reference that means quoting 2710900982 with the quantity and letting the packing follow.

Who It Is For

• Exporters and consolidators — shipping mixed cooling-system pallets into Europe, the Middle East and South America. They judge 2710900982 on one thing: whether it matches the part that came off.
• Aftermarket distributors — stocking cooling-system lines for Mercedes-Benz across a regional network and needing a reference-accurate catalogue behind the shelf. They judge 2710900982 on one thing: whether it matches the part that came off.
• 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 2710900982 by the carton and reorder against the same number.

Problems It Solves

Split ordering

Sourcing one hose from one supplier and the matching flange from another doubles the freight and the paperwork for the same repair. On 2710900982 that is settled before the quotation goes out.

Parts that are no longer produced

When the original reference is dropped, the repair still exists. Sample-based production and mould development keep the line alive. That is why 2710900982 carries its full cross-reference set on this page.

Returns from wrong fitment

Every returned part costs the freight twice. Checking the bellows pitch, the connector geometry and the sensor port position before despatch is cheaper than a credit note. For Mercedes-Benz buyers it is the difference between a stocked line and a credit note on 2710900982.

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 2710900982 and 2720903682 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 2710900982 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.
