Actual Item and Part Number Verification
Part Identification
Engine air filter box / air cleaner housing / airbox housing.
Used. Expect normal age-related marks, dust and cosmetic wear. Please inspect every actual item photograph.
Moulded black thermoplastic housing. The exact polymer grade is not independently confirmed, so no resin grade is being guessed.
Approximately 1.78 kg for the catalogue part. Actual packed shipping weight can differ.
The suffix BB matters. Do not assume another 3B0 133 837 suffix is interchangeable.
Only the components shown in the actual listing photos. Do not assume sensors, filter element, hoses, clips or ducts are included unless visible.
Verified Compatibility - Read Before Purchase
The moulded number on the photographed item is 3B0133837BB. Catalogue cross-reference places this part within Skoda Superb 3U and Volkswagen Passat 3B applications. Because multiple airbox variants were fitted within the same model years, the VIN and exact moulded number remain the final check.
| Make | Model / chassis | Body | Model years | Engine application | Fitment status |
|---|---|---|---|---|---|
| Skoda | Superb I - 3U / 3U4 | Four-door saloon | 2002-2008 | 2.5 V6 TDI applications using 3B0133837BB | CATALOGUE FAMILY VERIFIED - VIN + exact part-number match required |
| Volkswagen | Passat - 3B / B5.5 / 3BG | Saloon or Variant only where VIN catalogue confirms | 2001-2005 | 2.5 V6 TDI applications using 3B0133837BB | CATALOGUE FAMILY VERIFIED - VIN + exact part-number match required |
Vehicles and engines you should NOT assume this fits
| Vehicle / engine | Instruction | Reason |
|---|---|---|
| Skoda Superb 3U 2.0 petrol or 2.0 TDI | DO NOT LIST AS CONFIRMED FIT | The current eBay compatibility data shows 2.0 applications, but that conflicts with the part-number catalogue record for the BB housing. Confirm only by VIN and exact old-part number. |
| Skoda Superb 3U 1.8T or 1.9 TDI | DO NOT ASSUME FITMENT | Different intake housings were used across the 3U range. Require a VIN result for 3B0133837BB. |
| Skoda Superb II / 3T and later generations | NOT THIS GENERATION | Different vehicle platform and intake architecture. |
| VW Passat 3B non-2.5 engines | DO NOT ASSUME FITMENT | Passat 3B used multiple airbox suffixes. Only confirm when VIN and old housing resolve to 3B0133837BB. |
| VW Passat B6 / 3C and later | NOT THIS GENERATION | Different platform and intake system. |
| Any old housing with a suffix other than BB | DO NOT SUBSTITUTE BY APPEARANCE | The final suffix can identify a different moulding, engine application or connection layout. |
Where This Part Fits and What It Does
This housing is fitted in the engine-bay air-intake system. It encloses and seals the engine air-filter element, supports the intake ducting and routes cleaned air toward the airflow-meter/intake tract. It is a mechanical airflow and filtration enclosure; it does not itself electronically control the engine.
Why the housing matters: cracked plastic, broken mounting points, a warped lid or damaged sealing surfaces can allow unwanted noise, poor filter sealing or contaminated air to enter the intake path. A correct factory-fit housing also keeps the duct and sensor interfaces in their intended positions.
Possible Symptoms of a Damaged Airbox
- Visible cracks, broken clips, damaged lid edges or missing mounting points.
- Rattling, vibration or unusual induction noise from the engine bay.
- Air-filter element not clamping or sealing correctly inside the housing.
- Dust or debris visible downstream of the filter because the housing or seal is compromised.
- Airflow-meter contamination or intake-related running issues if the surrounding ducting/sensor connection is leaking or disturbed.
- Loose intake ducting or a hose connection that will not stay correctly aligned.
These symptoms are diagnostic clues only. Similar symptoms can have other causes. Diagnose the vehicle before replacing parts.
Why Choose the Correct Factory-Spec Used Housing
A correct factory-spec used housing retains the original mounting geometry, filter sealing surfaces, clip positions and duct/sensor interfaces designed for the vehicle. Low-cost pattern housings can vary in moulding accuracy and connection detail, which can create fitment or sealing problems.
Buying a serviceable recycled used part can also reduce cost compared with a new replacement. Depending on the part and current new retail price, savings can be as much as around 70 percent; this is a potential saving, not a guaranteed percentage for every part.
Fitting Guide
Typical workshop tools
- Torx driver set, commonly covering T20 to T30.
- Small metric socket set, commonly including 7 mm and 10 mm.
- Flat trim/clip tool or suitable flat-blade tool.
- Hose-clamp pliers or driver suitable for the clamp fitted to your vehicle.
- Inspection light and clean cloths.
Typical replacement sequence
- Park safely, switch the ignition off and allow the engine bay to cool.
- Before removal, photograph the routing of the intake ducting, wiring and clips.
- Confirm the old housing moulded number is 3B0 133 837 BB before dismantling further.
- Disconnect the airflow-meter electrical connector only if it is attached to the section being removed.
- Release the intake hose clamp and any cold-air feed/snorkel connections required for access.
- Release the airbox lid clips or screws and remove the filter element carefully.
- Remove the housing retaining fasteners or release it from its mounting grommets, depending on vehicle build.
- Transfer only matching grommets, sensor/duct parts or clips that are required and confirmed compatible.
- Inspect the filter element and sealing faces. Replace a dirty, damaged or poorly sealing filter rather than refitting it.
- Refit the housing, ensure it is fully seated, reconnect ducting/clamps and reconnect any electrical connector removed.
- Start the engine and check that there are no loose ducts, abnormal intake noises, warning lamps or obvious air leaks.
Do not invent torque settings. Use the vehicle workshop data for any fastener that has a specified torque.
Estimated Garage Labour Cost Guide
Because JavaScript and active content are not used, the labour calculator is presented as a static lookup table. Planning allowance: approximately 0.5 to 1.0 labour hour for a straightforward housing swap, excluding diagnosis, seized/broken fasteners, additional intake repairs and road testing. This is a planning estimate, not a manufacturer book time.
| Garage labour rate | 0.5 hour | 0.75 hour | 1.0 hour |
|---|---|---|---|
| £50/hour | £25.00 | £37.50 | £50.00 |
| £60/hour | £30.00 | £45.00 | £60.00 |

VAT Information
Returns - Clear and Fair
This listing currently offers 30-day returns. The returned part should be the exact item supplied and should come back in the same condition, complete and securely packaged.
For vehicle parts, installation can change condition. Where eBay rules permit and a returned item has been installed, altered, damaged, contaminated or returned incomplete, a deduction of up to 50 percent may be made to reflect actual loss in value. This is not an automatic 50 percent restocking fee and does not remove buyer rights where an item is faulty, incorrect or not as described.
If fitment is uncertain, contact us through eBay Messages with the VIN and old-part number before installation. The purpose of the fitment chart is to get the correct part ordered first time and reduce avoidable returns.
ThePartPilot Stock and Service
We hold more than 25,000 parts in stock and on the shelf at any one time. This listing is designed around actual item photography, exact part-number checking and clear fitment guidance rather than generic claims.
For this used item, the actual part photos above are more useful than generic warehouse, garage or dispatch stock photos. That keeps the description focused on the exact item and avoids implying that an unrelated stock image is our premises or the exact part being supplied.
Supporting Reuse and a Local Small Business
Choosing a serviceable used vehicle part keeps a usable component in circulation, can reduce demand for a newly manufactured replacement and helps support a UK small business. Reuse makes practical sense when the correct part can be identified, inspected and put back into service safely. Thank you for helping us keep good parts working rather than wasting them.
