S&B – Best Overall Cold Air Intake for 6.7 Cummins
Most cold air intakes for diesel trucks are a straight swap — bigger tube, better filter, done. S&B took a different approach with the 6.7 Cummins. Their kit retains the active air management logic of the factory system but completely rebuilds the hardware around it. The result is an intake that flows 54.60% better than stock while still protecting your engine from ice, rain, and road debris through a dedicated wheel well inlet that stays active during normal driving.
The real differentiator is the built-in swing gate. Under hard acceleration, high load, or high altitude — exactly the conditions where a diesel needs air most — the gate pivots open to access the ram-air duct behind the grille. That’s cooler, denser, less restricted air feeding directly into the engine at the moment it’s under the most demand. The enclosed airbox handles the rest, keeping engine heat and dirt away from the filter during everyday driving.
Hardware quality is a step above the typical intake kit. The silicone couplers are rated to 400°F and won’t slide, crack, or leave oily residue on your hands during filter maintenance. The filter itself is rated at 99% efficiency — impressive given the airflow numbers. For 2013–2018 Cummins owners who want a performance upgrade that thinks like an engineer rather than just bolting on a bigger pipe, S&B is the benchmark.
- 54.60% airflow improvement over stock
- Swing gate maximizes air under hard load
- Enclosed airbox blocks heat and debris
- Premium silicone couplers rated to 400°F
- Dual inlet option for unrestricted airflow
- Higher price than basic intake kits
- Swing gate system adds installation complexity
Expert Recommendation
If you want the most engineered cold air intake available for the 2013–2018 6.7 Cummins — one that actively manages airflow under load rather than just opening a bigger hole — S&B is the only kit on this list that delivers that level of sophistication without sacrificing everyday engine protection.
aFe Power Quantum – Best Performance Cold Air Intake for 6.7 Cummins
aFe built the Quantum around a simple idea: fewer parts, better results. Where most intake manufacturers stack up components and hope for the best, the Quantum uses an integrated filter-to-housing design that locks the filter to the sealed housing with four captive screws — a positive surface-area seal that eliminates the gaps and leaks that plague budget intakes over time. Installation follows the same logic: direct fit to factory mounting points, no cutting, no modifications, everything included.
The dyno numbers are what make this kit stand out. Up to 15 horsepower and 37 lb-ft of torque are verified gains — not marketing estimates — flowing 520 CFM at 7 inches of water, which translates to a 46% improvement over the factory intake. The intake tube is XLPE (cross-linked polyethylene), a material specifically chosen for its resistance to heat soak, which is a real problem on a diesel that runs hot under tow or grade.
The Pro DRY S filter is a three-layer synthetic media that requires no oil — which means no chance of oil contamination on the MAF sensor and no messy maintenance ritual between filter cleanings. It’s washable, reusable, and well-suited to both street driving and light off-road use. For 6.7 Cummins owners chasing real, measurable power gains without the headache of a complicated install, the aFe Quantum delivers on both counts. Note: not CARB exempt, not available in California.
- Dyno-proven +15 HP and +37 lb-ft torque
- Oil-free filter, no MAF sensor risk
- XLPE tube resists heat soak effectively
- Integrated housing seal, no air leaks
- Direct fit, no cutting or modifications needed
- Not CARB exempt, unavailable in California
- No enclosed airbox, less heat isolation
Expert Recommendation
For 6.7 Cummins owners who want verified dyno numbers, a no-oil filter, and an installation that takes minutes rather than an afternoon, the aFe Quantum is the most straightforward performance upgrade on this list. The power gains are real and the hardware is built to last.
