Turbo Charger Hose for BMW OEM 13717594721 13717571352

Product Overview

Ordered against OEM 13717594721 and 13717571352, this Turbo and Intercooler Hose replaces the original part in the charge air circuit on BMW vehicles. The carries pressurised charge air between the turbocharger, the intercooler and the inlet manifold, so form and fit are not negotiable. In service the part carries pressurised charge air between the turbocharger, the intercooler and the inlet manifold. When it fails it usually shows heat-hardened elbows and blown cuffs at clamp joints, and the driver sees boost loss under load, limp mode and a measurable drop in charge pressure. 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

• 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.
• Built for the duty of the charge air circuit — The part carries pressurised charge air between the turbocharger, the intercooler and the inlet manifold, so the compound and the wall construction are matched to that circuit rather than to a generic hose spec.

Application Scenarios

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. Here the turbo and intercooler hose is ordered against 13717594721 and travels with the rest of the BMW branch.

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. This reference, 13717594721, is bought for exactly that situation on BMW vehicles.

Rebuild of an obsolete platform

The original reference is no longer produced, so the part is made from a supplied sample. On this reference that means quoting 13717594721 with the quantity and letting the packing follow.

Who It Is For

• Workshop and fast-fit chains — replacing turbo and intercooler hoses on BMW daily and judging a supplier on whether the part fits first time. What they need from 13717594721 is that it fits the BMW on the ramp today.
• Online parts sellers — listing by OEM reference, where a mismatched number turns into a return and a negative rating. They order 13717594721 by the carton and reorder against the same number.
• Fleet and bus operators — running BMW vehicles past warranty and buying cooling-system parts by the box to keep downtime short. They order 13717594721 by the carton and reorder against the same number.

Problems It Solves

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 turbo and intercooler hose the answer is the reference, 13717594721, on every document.

Returns from wrong fitment

Every returned part costs the freight twice. Checking the cuff diameters, the bend angle and the clamp or quick-connect style at each end before despatch is cheaper than a credit note. For BMW buyers it is the difference between a stocked line and a credit note on 13717594721.

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. On 13717594721 that is settled before the quotation goes out.

Technical Features

The part serves the charge air circuit and carries pressurised charge air between the turbocharger, the intercooler and the inlet manifold. 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.

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 13717594721 and 13717571352 against the number on the part you removed. Do not match on outline alone.

2. Check the interfaces

   Compare the cuff diameters, the bend angle and the clamp or quick-connect style at each end 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 13717594721 rather than carrying the old one over.

5. Pressure check before handover

   Refill, bleed the circuit and check for blown cuffs at clamp joints at working temperature before the vehicle leaves.
