Exact current model and interface
The current manufacturer page identifies MX2326-US as an 86.6mm, 16-flute oil-filter wrench for BMW and Volvo applications. Motivx states that it is compatible with all BMW engines using a smooth-top oil-filter cap and most Volvo engines using a smooth-top cap, while warning that Volvo has exceptions in the fitment information. The defining fact is the smooth-top cap and 86.6mm/16-flute interface, not the BMW name alone. A buyer should compare the actual cap before ordering, especially where an engine family or model year has more than one housing.
Materials and drive options
The page specifies a CNC-machined 6061-T6 aluminum body, gunmetal anodizing, and a 7075-T6 aluminum drive hub with red anodizing. It provides the same two drive routes as the smaller Motivx wrench: a 3/8-inch ratchet or a 24mm/15/16-inch socket or wrench. That gives the technician a normal square-drive option and a direct hex option for access or controlled leverage. The manufacturer says the materials are high strength, but no independent torque or deflection test is supplied; this review therefore describes construction without converting marketing language into a performance rating.
Compatibility is cap-specific
The phrase “all BMW engines” on the product page is bounded by the smooth-top oil-filter-cap condition, and “most Volvo” is explicitly less than universal. The 86.6mm dimension and 16-flute count are the safer purchasing anchors. The source does not provide a complete BMW/Volvo year-by-year application table in the product information, so an exact vehicle match remains a required check. Do not substitute the 64.3mm MX2320-US, and do not assume a nearby 86.4mm description represents this current 86.6mm model. Variant identity matters here.
Service suitability
For a vehicle with the matching smooth-top cap, the socket-style interface is purpose-built for routine filter-cap removal and installation. The dual drive choices help accommodate a ratchet or a 24mm/15/16-inch wrench, while the machined body avoids the ambiguity of a broad adjustable tool. However, the source does not state engagement depth, torque limit, cap-removal instructions, or clearance dimensions. The responsible use case is therefore narrow and clear: match the cap, seat the tool completely, and follow the vehicle’s service procedure. No hands-on success or failure is claimed.
Ownership and finish
Motivx says this model is made in the USA, carries a limited lifetime warranty, and is shown with a 90-day satisfaction guarantee. Those policies can matter for a specialized socket that may be used infrequently, but they do not prove long-term durability under shop abuse. The anodized body and red hub are easy visual identifiers when several sizes are stored together. Keep the flutes clean, avoid substituting the wrench for an impact-rated socket unless the manufacturer’s instructions allow it, and inspect for damaged engagement surfaces; these are prudent practices, not sourced test findings.
What customer feedback can and cannot say
The exact product page shows a 5.0 aggregate from 41 reviews and includes comments identifying BMW N-series, S55, and M4 applications. Those comments support that some owners used the named model on those engines, but they are anecdotal and not a fitment database. One displayed review even notes a loose fit cold and removal difficulty warm, which is a useful caveat rather than a generalized defect claim. The page provides no controlled comparison against other sockets. Treat the feedback as limited owner context, not a substitute for cap measurement or vehicle lookup.
