Air Intake Hose Pipe for Mercedes-Benz OEM 1645051361

Product Overview

Air Intake Hose Pipe for Mercedes-Benz OEM 1645051361 covers the air intake tract on Mercedes-Benz applications. The reference set on file is OEM 1645051361, 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 torn bellows sections at the engine mount side and cracks around moulded sensor ports, 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

• Ordered by reference not by photo — The listing carries OEM 1645051361. You quote the number, we confirm against the same number, and the part that ships is the one on the invoice.
• Consolidate the platform in one order — Hoses, flanges and thermostat housings for the same platform ship on one pallet, which shortens the paperwork and the freight bill.
• 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.
• Checked on the features that matter — Inspection concentrates on the bellows pitch, the connector geometry and the sensor port position — the dimensions that put a part back in the box if they are wrong.

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. Here the air intake hose is ordered against 1645051361 and travels with the rest of the Mercedes-Benz branch.

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 1645051361 and travels with the rest of the Mercedes-Benz branch.

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. With 1645051361 on the list the rest of the air intake tract can be priced at the same time.

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. What they need from 1645051361 is that it fits the Mercedes-Benz on the ramp today.
• 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 1645051361 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 1645051361 is that it fits the Mercedes-Benz on the ramp today.

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. That is why 1645051361 carries its full cross-reference set on this page.

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, 1645051361, 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. That is why 1645051361 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.

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 1645051361 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 1645051361 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.
