Flashark Cold Air Intake Kit for 2007.5–2012 Dodge Ram 2500/3500/4500/5500 6.7L Cummins Diesel — Aluminum, Dry Reusable Filter

Your 6.7L Cummins needs air — lots of it. The factory intake chokes airflow and pulls hot under-hood air when you need it coldest: climbing a grade with 10,000 lb on the hitch. This Flashark cold air intake relocates the filter outside the engine bay, feeds the turbo with denser, oxygen-rich air, and wakes up throttle response right where you feel it — merging onto the highway, passing, and pulling hard in the mid-RPM range.

Built with lightweight T-304 aluminum tubing, a polished finish that resists corrosion, and a high-flow dry cone filter you wash and reuse, this kit bolts on with basic hand tools in about an hour. No tuning required, no cutting, no check engine light.

Expected gains: +7–10% horsepower, +6–8% torque. Results are conservative estimates; actual gains depend on existing mods.

Key Features

• T-304 aluminum intake tube — lightweight, corrosion-resistant
• Dry, washable cone air filter — no oil to foul your MAF sensor; clean and reinstall
• Filter relocation design — pulls cooler air from outside the engine bay, not hot under-hood air
• Optimized tube length & diameter — tuned to match the 6.7L Cummins intake resonance for maximum volumetric efficiency
• Improved throttle response — most noticeable in the low-to-mid RPM range where you tow and haul
• Lower intake air temps — more oxygen per combustion cycle = more complete burn = more torque
• Aggressive intake sound — deep turbo spool and intake note under load without drone at cruise
• Bolt-on installation — all hardware included, uses factory mounting points, average install time ~1 hour

How a 6.7 Cummins Cold Air Intake Boosts Performance

A cold air intake system relocates the filter outside of the engine compartment to deliver the coolest air inlet temperatures possible. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber—creating more horsepower and torque. But that's only part of the power equation. A well-designed 6.7 Cummins cold air intake also tunes the inlet pipe’s length and diameter to match the engine's natural resonance, helping move more air into the cylinders (think of your engine as a big air pump). This tuning allows for maximum power gains throughout the entire RPM range.
