Air Intake Hose Pipe for BMW OEM 13717795284 (WJ-H0398)

Product Overview

Air Intake Hose Pipe for BMW OEM 13717795284 (WJ-H0398) covers the air intake tract on BMW applications. The reference set on file is OEM 13717795284, 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 cracks around moulded sensor ports and hardened cuffs that no longer seal on the airbox spigot, 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

• 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.
• 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.
• 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

Warranty-expired fleet maintenance

A fleet past dealer coverage moves to independent supply and needs the same reference coverage at a working price. On this reference that means quoting 13717795284 with the quantity and letting the packing follow.

Counter stock for a busy platform

BMW volume in the region justifies holding the line on the shelf instead of ordering it in per job. With 13717795284 on the list the rest of the air intake tract can be priced at the same time.

Breakdown repair

The vehicle is off the road and the part has to be right the first time, which makes the reference match the whole decision. Here the air intake hose is ordered against 13717795284 and travels with the rest of the BMW branch.

Who It Is For

• Online parts sellers — listing by OEM reference, where a mismatched number turns into a return and a negative rating. 13717795284 earns its shelf space through repeat demand on BMW platforms.
• Fleet and bus operators — running BMW vehicles past warranty and buying cooling-system parts by the box to keep downtime short. They judge 13717795284 on one thing: whether it matches the part that came off.
• Radiator and cooling specialists — rebuilding cooling systems and sourcing the hoses, flanges and housings for a platform in one go. What they need from 13717795284 is that it fits the BMW 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. With 13717795284 the check is the bellows pitch, the connector geometry and the sensor port position, and it happens before despatch.

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. For this air intake hose the answer is the reference, 13717795284, on every document.

Unclear compound

PA66 mouldings crack rather than weep, so a hairline split can empty a coolant system quickly once it opens. For BMW buyers it is the difference between a stocked line and a credit note on 13717795284.

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 PA66 glass-filled nylon, chosen because glass-filled PA66 gives a rigid pipe that holds its shape against vibration and keeps clamp faces dimensionally stable at under-bonnet temperature.

Used where the part must hold a fixed geometry and carry bolted or clipped interfaces. PA66 mouldings crack rather than weep, so a hairline split can empty a coolant system quickly once it opens.

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 13717795284 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. PA66 mouldings crack rather than weep, so a hairline split can empty a coolant system quickly once it opens.

4. Fit with the original clamp style

   Reuse the clamp type the BMW platform was designed around, and fit any seal or O-ring supplied with 13717795284 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.
