Product Overview

Air Intake Hose Pipe for Mercedes-Benz OEM 2780904982 is a direct-reference replacement for the air intake tract of Mercedes-Benz vehicles. It is listed here against OEM 2780904982, so the part can be matched to a vehicle without guesswork. The air intake tract gives this part a hard life: heat soak, vibration and pressure cycling. Typical end-of-life signs are hardened cuffs that no longer seal on the airbox spigot and splits along the convolutions, which reach the workshop as unmetered air downstream of the mass airflow sensor, a rough idle and airflow fault codes. The part belongs to a cooling-system catalogue of more than 4000 types, which is the practical reason buyers consolidate a mixed pallet with us rather than splitting it across suppliers.

Key Benefits

  • 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.
  • Inspection before despatch — Parts are inspected before they leave, which for this family means checking the sealing faces and the connector geometry that decide whether it fits.
  • Matched to how the part actually fails — Hardened cuffs that no longer seal on the airbox spigot and splits along the convolutions are the reasons this reference is bought, so those are the features checked before packing.
  • 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.

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. On this reference that means quoting 2780904982 with the quantity and letting the packing follow.

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. On this reference that means quoting 2780904982 with the quantity and letting the packing follow.

Warranty-expired fleet maintenance

A fleet past dealer coverage moves to independent supply and needs the same reference coverage at a working price. Here the air intake hose is ordered against 2780904982 and travels with the rest of the Mercedes-Benz branch.

Who It Is For

  • Aftermarket distributors — stocking cooling-system lines for Mercedes-Benz across a regional network and needing a reference-accurate catalogue behind the shelf. They order 2780904982 by the carton and reorder against the same number.
  • 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 judge 2780904982 on one thing: whether it matches the part that came off.
  • Online parts sellers — listing by OEM reference, where a mismatched number turns into a return and a negative rating. What they need from 2780904982 is that it fits the Mercedes-Benz on the ramp today.

Problems It Solves

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 2780904982.

Long lead times on slow movers

A slow line ordered alone waits for a container. Consolidated with fast movers it travels on the same shipment. That is why 2780904982 carries its full cross-reference set on this page.

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. For Mercedes-Benz buyers it is the difference between a stocked line and a credit note on 2780904982.

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.

Use Guide

  1. Confirm the reference

    Match OEM 2780904982 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 2780904982 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.

Answers

Air Intake Hose Pipe for Mercedes-Benz OEM 2780904982 — Questions Before You Order

What OEM references does this part cross to

It is catalogued against OEM 2780904982. Our internal reference is WJ-H1168, which is the number to quote on repeat orders. If your reference is not on the list, send it with the vehicle details and we will check it against the range.

Why is this part made in Reinforced composite

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. The steel helix is what stops the duct collapsing, so any duct that has been crushed in transit should be rejected on arrival.

What is the minimum order quantity and the price

MOQ and price depend on the reference and the quantity mix, and are confirmed per enquiry rather than published. Email [email protected] with the reference and the quantity you need and you get a written quotation with packing details.

Can you supply a part that is not listed on this site

Yes. The range runs to more than 4000 types and not all of it is published. Send the OEM reference, or the old part or a drawing, and we quote from the sample — including mould development where the tooling no longer exists.

How is the part packed for export

Parts ship in cartons marked with the reference, packed for sea freight to Europe, the Middle East and South America. Carton counts and dimensions are confirmed on the quotation so you can plan the container load.

How do I check the part fits before fitting it to the vehicle

Compare the bellows pitch, the connector geometry and the sensor port position against the part you removed. Those are the features that decide fitment on this family; a match on outline alone is not enough.

What certifications do you hold

Certification documents are not published on this site. Ask for the current documentation by email with your market in mind and we will send what applies to the reference you are buying.
