If you own a 2007.5 to 2024 Dodge Ram with the 6.7L Cummins, you already know that it is an absolute beast of a motor. It hauls heavy loads, reliable for daily driving, and also has unmatched durability. 

But if you’ve ever popped the hood, you’ve probably noticed an area where factory engineering was a little disappointing, the brittle, boring factory plastic breather cover.

At D&J Precision Machine, we believe your engine components should match the heavy duty nature of the truck itself. That’s why we engineered the all new Billet Cummins Breather Cover, the perfect blend of aesthetics, maximum durability, and seamless function. Available in a natural or black powder coated finish. 

Engineered to Last

We designed this breather cover at our shop to give truck owners a high end upgrade without the inflated price tag.

Instead of cheap factory plastic that can warp or degrade over years of heat cycles, each D&J Breather Cover is precision-machined from aerospace-grade 6061-T6 billet aluminum. This means exceptional structural integrity, great heat dissipation, and a beautiful look under the hood. To ensure you never have to worry about the elements, we package it with all stainless steel fasteners for total corrosion resistance.

Zero Hassle, Full OEM Integration

A common headache with aftermarket breather covers is that they require you to re-engineer your Crankcase Ventilation (CCV) system, forcing you to purchase aftermarket catch cans or reroute hoses.

We don’t think a great upgrade should make your life more complicated. Our Billet Breather Cover retains the factory CCV system entirely. It is a direct bolt-on replacement for OEM parts.

Even better? We include a custom D&J powder-coated oil cap cover to bring the whole look together.

The Best Part? 50-State Legal

Modifying your truck shouldn't come with the anxiety of compliance check-ups. Because our breather cover maintains the integrity of your OEM emissions equipment by nature of its smart design, it is 100% legal for sale and use in all 50 states (including California). No EO number required.

A 30-Minute Transformation

You don't need a professional shop or a weekend-long window to get this installed. The D&J Billet Breather Cover is designed for user convenience with a realistic install time of just 30 minutes. With standard tools, you can completely transform the look and durability of your 6.7L Cummins engine bay before your lunch break is over.

We stand behind our craftsmanship, which is why this cover comes backed by our 36-Month Parts Warranty.
