Air Intake Hose Pipe for Mercedes-Benz OEM 1120943682

Product Overview

Ordered against OEM 1120943682, this Air Intake Hose replaces the original part in the air intake tract on Mercedes-Benz vehicles. The carries filtered air from the airbox to the turbocharger inlet or throttle body, so form and fit are not negotiable. The air intake tract gives this part a hard life: heat soak, vibration and pressure cycling. Typical end-of-life signs are splits along the convolutions and torn bellows sections at the engine mount side, 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

• 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.
• 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 — Splits along the convolutions and torn bellows sections at the engine mount side are the reasons this reference is bought, so those are the features checked before packing.
• Export packing as standard — The range ships to Europe, the Middle East and South America, so cartons are packed for long sea legs rather than for a local van run.

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 1120943682 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 1120943682 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. This reference, 1120943682, is bought for exactly that situation on Mercedes-Benz vehicles.

Who It Is For

• Fleet and bus operators — running Mercedes-Benz vehicles past warranty and buying cooling-system parts by the box to keep downtime short. For them 1120943682 is a line on a shelf, not a project.
• Radiator and cooling specialists — rebuilding cooling systems and sourcing the hoses, flanges and housings for a platform in one go. They order 1120943682 by the carton and reorder against the same number.
• Exporters and consolidators — shipping mixed cooling-system pallets into Europe, the Middle East and South America. 1120943682 earns its shelf space through repeat demand on Mercedes-Benz platforms.

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 this air intake hose the answer is the reference, 1120943682, on every document.

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 1120943682 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 this air intake hose the answer is the reference, 1120943682, 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.

Comparison With the Alternatives

Use Guide

1. Confirm the reference

   Match OEM 1120943682 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 1120943682 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.
