What Is the Oil Filter Number for a 2011 BMW 335i?
The commonly used oil filter number for a 2011 BMW 335i with the N55 3.0L turbocharged inline-six engine is typically referenced as BMW part number 11 42 7 566 327, which is often cross‑listed in the aftermarket as HU 816 X (MANN-FILTER) or equivalent. However, exact fitment can vary slightly by production date and body style, so it is essential to confirm using the vehicle’s VIN before purchase.

Understanding the 2011 BMW 335i Oil Filter Specification
The 2011 BMW 335i sold in the United States and most global markets is equipped with the N55 3.0L turbocharged inline-six engine. This engine uses a cartridge-style oil filter element housed in an aluminum filter housing on top of the engine, rather than a spin‑on filter. The factory specification for this filter is BMW’s own part number, which many major filter manufacturers match with compatible products.
Primary OEM and Common Aftermarket Part Numbers
The following section explains the main OEM and widely used aftermarket oil filter part numbers that are typically listed as compatible with a 2011 BMW 335i equipped with the N55 engine. These numbers are what you will usually see on retailer websites and parts catalogs.
- BMW OEM: 11 42 7 566 327 (often written as 11427566327)
- MANN-FILTER: HU 816 X (one of the most common, often considered the “benchmark” for this application)
- Mahle / Knecht: OX 187/1D or equivalent listing for N55 applications
- WIX: 57341 (cartridge-style filter for N55 in many catalogs)
- Fram: CH10075 (or current equivalent listed for BMW N55 engines)
- STP / AutoZone house brand: S10075 or similarly numbered equivalents cross‑referenced to HU 816 X
- Bosch: Filters in the “P” or “D” series cross‑referenced to HU 816 X (check latest catalog by VIN)
These part numbers generally describe the same basic filter layout and dimensions required by the N55 engine, with the BMW OEM number serving as the reference point and the aftermarket brands offering compatible alternatives that match or exceed the factory specifications.
Why the Exact Oil Filter Number Can Vary
Although the BMW part number 11 42 7 566 327 and its MANN equivalent HU 816 X are widely accepted for the 2011 335i, there are nuances in BMW’s engine family and trim variations that make VIN confirmation important, especially for cars built near model‑year transitions or with different regional specifications.
Engine Variants: N55 vs. N54 Considerations
Most 2011 BMW 335i models use the single‑turbo N55 engine, which is what the part numbers above are based on. However, there are special variants—particularly performance models like the 335is or some late‑run N54‑equipped cars in specific markets—that can share the 335i badge but use a different internal filter listing in some catalogs. In practice, the N54 and N55 typically share the HU 816 X style filter, but catalog part numbering can differ by supplier.
Production Date and Market Differences
BMW sometimes supersedes part numbers during a model’s production life. A filter that originally shipped under one BMW number might later be replaced by a new part number with the same physical fit and function. Likewise, some regions may show a slightly different BMW number due to localized packaging or supplier changes, even though the filter itself is functionally identical.
How to Confirm the Correct Oil Filter for Your Specific 2011 335i
Because BMW’s catalog and aftermarket cross‑references evolve, owners should verify fitment rather than relying solely on one generic part number. This is especially important if the vehicle is a 335is, xDrive model, has been modified, or was originally delivered in a non‑U.S. market.
The following list describes the most reliable ways to confirm the correct oil filter number for your specific 2011 BMW 335i before you buy or install the part.
- Use your VIN in an official BMW parts catalog: Enter the full VIN into BMW’s online ETK or a reputable OEM parts site. This will display the exact current BMW part number for the oil filter for your individual car.
- Check a trusted aftermarket catalog: MANN, Mahle, WIX, Bosch, and other major brands allow VIN or vehicle‑specific lookups, which cross‑reference directly to their correct filter number.
- Confirm with your dealer or independent specialist: A BMW dealer parts department or an experienced independent BMW shop can quickly confirm the correct filter number from the VIN and, if needed, check for any superseded or updated part numbers.
- Verify physically if in doubt: If the filter is being replaced and the old part is still available, match its size and design to the new filter, ensuring the proper O‑rings and end‑cap geometry align with the housing.
Using one or more of these methods reduces the risk of installing an incorrect filter, which could compromise oil flow, cause leaks, or affect long‑term engine reliability.
Why Using the Correct Filter Matters
The oil filter on the 2011 BMW 335i is more than a simple consumable; it is a critical component in maintaining proper lubrication and protecting the turbocharged N55 engine from premature wear. BMW’s oiling system operates at high pressures and temperatures, and the design of the cartridge filter plays a specific role in controlling flow and filtration efficiency.
Fit, Sealing, and Oil Pressure
An incorrect or low‑quality filter may not seal properly in the housing, leading to internal bypassing—where unfiltered oil circulates in the engine—or to external leaks around the filter cap. Either scenario risks contamination of sensitive turbochargers, bearings, and valvetrain components, and could trigger oil pressure warnings in severe cases.
Service Intervals and Oil Specification
BMW’s official service schedules for the 2011 335i often specify long (up to roughly 10,000–15,000 miles) oil change intervals, though many enthusiasts shorten this to 5,000–7,500 miles to better protect the N55 engine. Using a filter that meets BMW’s specifications (often alongside an LL‑01 approved synthetic oil) ensures that the filter has the capacity and filtration performance to operate safely across those intervals.
Summary
For a 2011 BMW 335i with the N55 3.0L turbocharged engine, the commonly referenced oil filter is BMW part number 11 42 7 566 327, widely cross‑listed in the aftermarket as MANN HU 816 X and equivalent filters from Mahle, WIX, Fram, Bosch, and others. While this is the standard fitment for most 2011 335i models, the safest approach is to verify the exact filter using the vehicle’s VIN through an official BMW catalog, a reputable parts site, or a dealer or specialist. Ensuring the correct filter and matching it with the proper oil specification is essential to maintaining oil pressure, filtration performance, and long‑term engine health in BMW’s turbocharged N55 platform.
