CarCareTruth's Analysis
Last reviewed May 26, 2026
TL;DR No published SAE J1858 or ISO 16889 test data — the 22-micron retail spec carries no named test standard. No cut-open review located; bypass is OEM-integrated into the BMW housing, and no bypass or dry-start failures appear in 4,461 reviews.
What it is and how it performs
Cartridge-style replacement element for the BMW top-mounted oil filter housing on N52, N54, N55, and N20 engines — only the paper element is replaced; housing and bypass valve stay on the engine. Media is cellulose per Amazon spec and manufacturer description. No independent multi-pass filtration test data located; the 22-micron retail spec carries no cited method. No cut-open review found; construction quality scored conservatively. Mann+Hummel supplies the OEM BMW filter element — the HU 816 x is the same part without BMW packaging. Zero fitment failures in 4,461 reviews.
Who should buy this — and who should skip it
Right pick for a BMW N52/N54/N55/N20 owner on 5,000–7,500 mile oil changes seeking OEM-equivalent construction below dealer pricing. Skip for extended-drain programs — a full-synthetic extended-drain filter element is the appropriate choice.
Safety and environmental impact
No chemical exposure pathway — cartridge oil filter element is a passive mechanical accessory with no SDS. Spent elements contain residual motor oil, a hazardous waste in most US jurisdictions; drained elements are accepted at most automotive parts stores.
Frequently asked questions
Is this the same filter as the BMW OEM oil filter?▾
Yes — Mann+Hummel is the OEM manufacturer that supplies BMW's oil filter elements. The HU 816 x is the same filter element sold without BMW packaging. OEM part numbers 11427566327, 11427541827, 11427854049, and others cross-reference to this part.
What's included in the kit?▾
The HU 816 x kit includes the filter element, an O-ring, and a drain plug washer (copper). These are visible in the product images — the element is a black cylindrical paper cartridge with a green secondary O-ring also included.
Is this an Amazon add-on item?▾
Yes — the ASIN B001DRHMRI is flagged as an Amazon add-on item, which means it requires a qualifying order above a minimum threshold or a Subscribe & Save enrollment to purchase standalone. The 3-pack (B01NCVMOSY) and 6-pack (B006B0ZW6U) may not carry the same restriction.
What BMW models does this filter fit?▾
The HU 816 x fits BMW models on the N52, N54, N55, and N20 engine platforms, including the 1 Series (128i, 135i), 2 Series (228i, M235i), 3 Series (320i, 328i, 335i), 4 Series (428i, 435i), X1, X3, X5, X6, and Z4, among others. Verify fitment against your specific year and model before ordering.
Does this filter have an anti-drain-back valve?▾
No — the HU 816 x is a cartridge element and does not incorporate an anti-drain-back valve in the element itself. The BMW oil filter housing integrates the drain-back mechanism and bypass valve. This is the standard architecture for BMW cartridge-style filter systems. No dry-start or slow-pressure-build complaints appear in the 4,461-review sample.

⭐⭐⭐⭐⭐ Perfect fit and excellent quality
I purchased the MANN-FILTER HU 816 x cartridge oil filter for my oil change, and it fit perfectly with no issues at all. The quality is immediately noticeable. The filter feels well made, with sturdy materials and clean construction, which is what I expect from MANN filters.Installation was straightforward, and it seated properly in the housing without any leaks or problems. After the oil change, the engine runs smoothly, and everything performs as it should.I’ve used MANN filters before, and this one continues to meet the same high standard. It gives me confidence knowing I’m using a reliable filter that matches OEM quality.Overall, this is a high-quality oil filter that does exactly what it’s supposed to do. If you’re looking for a dependable cartridge oil filter, this one is a solid choice and well worth the price.
