Air Intake Hose Pipe for Mercedes-Benz OEM 1120943482

Product Overview

Air Intake Hose Pipe for Mercedes-Benz OEM 1120943482 is a direct-reference replacement for the air intake tract of Mercedes-Benz vehicles. It is listed here against OEM 1120943482, so the part can be matched to a vehicle without guesswork. This part carries filtered air from the airbox to the turbocharger inlet or throttle body. The failure modes that bring it across a parts counter are cracks around moulded sensor ports and hardened cuffs that no longer seal on the airbox spigot, reported 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

• 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 — 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.
• 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.
• One reference set on every document — OEM 1120943482 appears on the quotation, the packing list and the carton label, so a warehouse can check a delivery without opening the box.

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 1120943482 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. With 1120943482 on the list the rest of the air intake tract can be priced at the same time.

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 1120943482 and travels with the rest of the Mercedes-Benz branch.

Who It Is For

• Exporters and consolidators — shipping mixed cooling-system pallets into Europe, the Middle East and South America. What they need from 1120943482 is that it fits the Mercedes-Benz on the ramp today.
• Aftermarket distributors — stocking cooling-system lines for Mercedes-Benz across a regional network and needing a reference-accurate catalogue behind the shelf. They judge 1120943482 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 1120943482 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 1120943482 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. For this air intake hose the answer is the reference, 1120943482, on every document.

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 this air intake hose the answer is the reference, 1120943482, on every document.

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 1120943482 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 1120943482 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.
