Capri Tools Oil Drain Plug Wrench for BMW & Mercedes-Benz — 17 mm box / 14 mm hex, low-profile offset

The Capri Tools Oil Drain Plug Wrench is a low-profile, dual-ended tool with a 17 mm box end and a 14 mm hex driver designed to reach oil, transfer case, and differential drain plugs on most BMW and Mercedes-Benz vehicles.

When you need faster, cleaner fluid changes on German cars, the right tool makes the job simpler. This Capri Tools wrench combines a 17 mm boxed end for oil drain plugs with a 14 mm hex end for transfer case and differential plugs. Its offset, low-profile shape fits into tight engine bays where standard sockets and ratchets struggle, reducing stripped fasteners and awkward extensions.

How does this wrench make oil and fluid changes easier?

The dual-ended design removes the need to switch tools between oil and drivetrain plugs. With a dedicated 17 mm box end and a 14 mm hex driver on the opposite end, you can quickly address both oil and transfer case or differential plugs. The offset profile improves access under splash shields and within cramped underbody cavities.

• 17 mm box end grips oil drain plug head securely to prevent rounding.
• 14 mm hex driver fits transfer case and differential drain plugs.
• Low-profile offset reaches recessed plugs where sockets cannot.
• Single-piece construction reduces wobble and slippage.

Which BMW and Mercedes-Benz models is it compatible with?

This wrench targets vehicles that use 17 mm oil drain plugs and 14 mm transfer case or differential plugs, common across many BMW and Mercedes-Benz models. It’s suitable for both older and newer cars when those plug sizes are specified. Always confirm plug size in your vehicle’s service information before use.

• Designed for BMW and Mercedes-Benz vehicles that specify 17 mm oil drain plugs.
• 14 mm hex end handles transfer case and differential plugs on compatible models.
• Works on most model years where plug sizes match, including popular series and C/E classes.

Can this tool access plugs that standard sockets can’t reach?

Yes—the low profile and offset geometry were engineered for confined spaces. Unlike traditional sockets that require extensions or universal joints, this wrench slides into tight areas and provides leverage without bulky attachments. That means faster, safer removal of drain plugs without stripping or rounding heads.

• Offset head clears obstructions such as crossmembers and shields.
• Low vertical profile fits shallow cavities under the vehicle.
• Box end design keeps firm contact to reduce slipping while turning.

The Capri Tools oil drain plug wrench is crafted to be straightforward and durable for shop or DIY use. Its compact, single-piece design eliminates joints that can fail and preserves torque transfer for stubborn plugs. The finishes are corrosion-resistant to withstand contact with oil and road grime.

• Dual-ended: 17 mm boxed end and 14 mm hex driver on opposite ends.
