07.5-12 Ram 6.7L Cummins Sinister Cold Air Intake

Before Sinister Diesel puts their name on any part they manufacture, it has to beat the competition in 5 ways: Strength; Performance; Simplicity; Durability; and Fit. The Sinister 6.7 cold air intake meets all those requirements, and more. Sinister's intakes come with a dry, washable filter that is desiged for the lifetime of the truck.

STRENGTH: Sure, they could build their intake out of plastic like everyone else, but aluminum is stronger. For example, aluminum won’t crack like plastic. Plus, unlike plastic, aluminum holds up to the wide temperature extremes common in every engine compartment.

PERFORMANCE: All the bends in their aluminum tubes are CNC mandrel bent and engineered for maximum air flow. Plus, our cold air intakes go all the way from the filter to the turbo, feeding your engine the cold air it needs. As everyone knows, better airflow means better performance.

DURABILITY: Rubber couplers may meet industry standards, but they don’t meet theirs. They use superior silicone couplers because they are best at providing years of reliable performance while resisting your engine’s temperature extremes.

FIT: Your components are only as good as their fitment. Sinister cold air intakes are designed, engineered and fabricated in-house. That means they control the manufacturing process from concept to prototype to testing to production. The result is the lowest tolerances for fitment variability combined with the highest levels of quality control.

SIMPLICITY: The best ideas are simple ones. We believe the same is true of parts, especially when it comes to installation. Their air intakes install in just a few hours, with common tools and minimal experience. Plus, each kit comes with full color instructions and all the necessary couplers and clamps you need to get the job done fast.

MORE: Their 6.7 air intake is polished and powder coated in their unique Sinister blue, providing a clean, distinctive look under your hood. Pick up your air intake today and experience Sinister’s 5 quality standards for yourself.

Sinister Diesel part number: SD-CAI-6.7C.
