The Ultimate 6.7L Cummins Billet Breather Cover Upgrade
The Ultimate 6.7L Cummins Billet Breather Cover Upgrade
If you own a 2007.5 to 2024 Dodge Ram with the 6.7L Cummins, you know it's an absolute beast of a motor. It hauls heavy loads, is reliable for daily driving, and has unmatched durability. But pop the hood, and you'll likely notice one of the factory's disappointments: the brittle, boring 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. It's available in finishes like natural aluminum and black powder-coat.
Engineered to Last
We designed this breather cover 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 for exceptional structural integrity and a beautiful look under the hood. Key features include:
- Aerospace-grade 6061-T6 billet aluminum construction
- Superior heat dissipation compared to factory plastic
- All stainless steel fasteners included 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. 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 compliance anxiety. Because our breather cover maintains the integrity of your OEM emissions equipment, it is 100% legal for sale and use in all 50 states (including California). No EO number is required.
A 30-Minute Transformation
You don't need a professional shop or a weekend-long window for this installation. 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.
The basic installation process involves:
- Disconnecting the CCV hose from the factory cover.
- Removing the factory bolts and the old plastic cover.
- Positioning the new D&J billet cover with its gasket.
- Securing the new cover with the provided stainless steel hardware.
We stand behind our craftsmanship, which is why this cover comes backed by our 36-Month Parts Warranty.
