Air Intake Hose Pipe for Mercedes-Benz OEM 6420948897

Product Overview

A Air Intake Hose for Mercedes-Benz vehicles, held against OEM 6420948897 and 2720901282. In service the part carries filtered air from the airbox to the turbocharger inlet or throttle body. 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. 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

• One reference set on every document — OEM 6420948897 and 2720901282 appears on the quotation, the packing list and the carton label, so a warehouse can check a delivery without opening the box.
• 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.
• 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.

Application Scenarios

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 6420948897 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. With 6420948897 on the list the rest of the air intake tract can be priced at the same time.

Counter stock for a busy platform

Mercedes-Benz volume in the region justifies holding the line on the shelf instead of ordering it in per job. On this reference that means quoting 6420948897 with the quantity and letting the packing follow.

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 6420948897 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. 6420948897 earns its shelf space through repeat demand on Mercedes-Benz platforms.
• Online parts sellers — listing by OEM reference, where a mismatched number turns into a return and a negative rating. 6420948897 earns its shelf space through repeat demand on Mercedes-Benz platforms.

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 6420948897 carries its full cross-reference set on this page.

Reference mismatch

Visually identical parts carry different connector geometry between model years. Quoting OEM 6420948897 and 2720901282 fixes the identity before money moves. With 6420948897 the check is the bellows pitch, the connector geometry and the sensor port position, and it happens before despatch.

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 6420948897 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.

Comparison With the Alternatives

Use Guide

1. Confirm the reference

   Match OEM 6420948897 and 2720901282 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 6420948897 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.
