Air Intake Hoses and Pipes

This section lists 41 air intake hoses and pipes references for German, French, Japanese, American and Korean vehicles. Matching runs from the OEM reference, which is the only way to keep a mixed order accurate.

Parts in this group fail by splits along the convolutions and hardened cuffs that no longer seal on the airbox spigot, so the replacement decision is usually made under time pressure at the counter.

Who This Group Is For

Online parts sellers

listing by OEM reference, where a mismatched number turns into a return and a negative rating.

Fleet and bus operators

running these platforms vehicles past warranty and buying cooling-system parts by the box to keep downtime short.

Radiator and cooling specialists

rebuilding cooling systems and sourcing the hoses, flanges and housings for a platform in one go.

Problems solved

What Goes Wrong Without the Right Reference

Unclear compound

Compounds differ between visually identical parts.

Reference mismatch

Visually identical parts carry different connector geometry between model years. Quoting the OEM number fixes the identity before money moves.

Split ordering

Sourcing one hose from one supplier and the matching flange from another doubles the freight and the paperwork for the same repair.

Materials in this group

What the Parts Are Made From

MaterialWhy it is used hereReferences
EPDM rubberEPDM keeps its elasticity through repeated heat cycles and resists ozone, water and weathering, which makes it the workhorse wall compound for moulded engine-bay lines.1
Non-woven fabric with steel reinforcement and PP connector / TEEEA 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.22
PA66 glass-filled nylonGlass-filled PA66 gives a rigid pipe that holds its shape against vibration and keeps clamp faces dimensionally stable at under-bonnet temperature.12
TEEE thermoplastic elastomerTEEE combines a flexible bellows section with rigid moulded ends, so one part can absorb engine movement and still seal on a hard spigot.6
Application scenarios

Where These Parts Are Fitted

Mixed container for a distributor

A quarterly container is filled across families — intake, charge air, coolant and thermostat lines — to a single packing list.

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.

Warranty-expired fleet maintenance

A fleet past dealer coverage moves to independent supply and needs the same reference coverage at a working price.

Air Intake Hoses and Pipes — Buyer Questions

How many air intake hoses and pipes references are published

41 references are published in this group. They cover Audi, BMW, Ford and Mercedes-Benz and are listed against the OEM numbers they replace. The wider cooling-system range runs to more than 4000 types.

Which materials are used across this group

EPDM (1 references), Reinforced composite (22 references), PA66 (12 references), TEEE (6 references). Material is listed per reference rather than per group, because two parts with the same outline are often moulded in different compounds.

What should I check before ordering from this group

Check the bellows pitch, the connector geometry and the sensor port position. Those are the features that decide fitment on this family, and they are what separates two references that look the same in a photograph.

How quickly can this group be quoted

Email the reference numbers and quantities to [email protected]. A written quotation comes back with packing details and carton counts so you can plan the container load.

Can parts from this group ship with other families

Yes. Mixing intake, charge air, coolant and thermostat lines on one pallet is the normal way this range is bought, and it keeps the freight cost per line down.

What if my reference is not published here

Send it anyway. Publication on this site is a subset of the range, and where a reference is out of production we quote from a supplied sample including mould development.
