BMP 25-26 Ram 6.7 Cummins Billet Oil Filter Cap

Black Market Performance Billet Oil Filter Cap | 2025–2026 6.7L Cummins

Replace the weak factory oil filter cap on your 2025–2026 6.7L Cummins with the Black Market Performance Billet Oil Filter Cap. The OEM cap is manufactured from thin cast aluminum and has become known for seizing, rounding off, and even breaking during routine oil changes. When that happens, a simple maintenance service can quickly become an expensive and time-consuming repair.

The Black Market Performance Billet Oil Filter Cap is precision CNC machined in the USA from premium billet aluminum, providing significantly greater strength and durability than the factory design. Built to handle repeated oil filter services, our billet cap offers a precise fit, improved serviceability, and the confidence that it won't fail when it's time for your next oil change.

Whether your truck is stock, towing every day, or making serious horsepower, this is a simple upgrade that eliminates one of the weak points in the factory oil filtration system.

Installation Recommendations

For the best results, Black Market Performance recommends installing a new oil filter whenever replacing the oil filter cap. A new O-ring is included with genuine Fleetguard oil filters, ensuring a proper seal during installation.

Before installing the billet cap:

• Install the new O-ring supplied with your new Fleetguard oil filter.
• Swap Allen Head Plug on top
• Apply a light coat of clean engine oil to the O-ring.
• Lightly lubricate the cap threads with clean engine oil to help prevent galling and seizing during future oil changes.
• Tighten the cap to the factory torque specification.

Upgrade your 2025–2026 Cummins with a billet oil filter cap that's built to outlast the factory design and make future maintenance easier and more reliable.
