Air Intake Systems

Our truck air intake system lineup covers both gas and diesel engines — including the 5.0L Coyote and 3.5L EcoBoost on F-150, 6.7L Power Stroke and 7.3L Godzilla on Super Duty, 5.7L HEMI and 6.7L Cummins on Ram, 5.3L and 6.2L V8 on Silverado and Sierra, 6.6L Duramax on GM HD, and the 3.5L V6 on Tundra. Whether you need the best cold air intake for your Ram 2500 Cummins, an aFe Momentum GT cold air intake for your F-150 5.0, or a cold air intake for your Silverado 1500 5.3L, every kit ships with all required hardware, filters, and installation components included. We also stock replacement performance air filters in both oiled (Pro 5R) and dry (Pro DRY S) media, snorkel kits for Jeep Wrangler JL, turbo upgrades, throttle body spacers, and E-PAS positive air shutoff systems for diesel trucks.

aFe, S&B, BD Diesel & Pacbrake Intake Systems for Gas & Diesel Trucks

Our cold air intake kit selection includes aFe Power Momentum GT, Momentum HD, Momentum XP, and Magnum Force systems across the full truck lineup. For diesel performance, we carry BD Diesel Screamer turbo upgrades for Cummins and EcoBoost engines, Pacbrake E-PAS and X-Series positive air shutoff systems for Power Stroke, Cummins, and Duramax platforms, and aFe ProGuard diesel filter master packs for scheduled maintenance. Snorkel kits from Rugged Ridge give Wrangler JL and Gladiator owners deep-water fording capability and raised air intake positioning for dusty trail conditions.

Pair your cold air intake with a performance Exhaust system from MBRP or Borla for maximum airflow gains, or add a Programmers tuner from SCT or Banks Power to optimize your engine calibration for the increased airflow. Monitor your engine vitals with Gauges and A-pillar pods from AutoMeter, or upgrade your Fuel Systems with an AirDog or FASS fuel air separation system for diesel reliability. Browse all intake, exhaust, tuner, and fuel upgrades under our Performance collection.

For truck exterior protection, check out Exterior for tonneau covers, fender flares, and mud flaps. Lift your truck with kits from Suspension, add a trailer hitch from Towing, or upgrade your rims and tires from Wheels.

Frequently Asked Questions

Do cold air intakes actually increase horsepower on trucks?

Cold air intakes increase horsepower by replacing the restrictive factory air box with a high-flow intake tube and performance air filter that pulls cooler, denser air into the engine. On most gas trucks, gains range from 5 to 20 horsepower depending on the engine and intake design. On diesel trucks, the gains can be higher when paired with an exhaust system and tuner. The biggest improvement most drivers notice is sharper throttle response and a more aggressive intake sound.

Is a cold air intake worth upgrading from the stock air box?

The stock air box on most trucks is designed for noise reduction and emissions compliance, not maximum airflow. A cold air intake removes that restriction and allows the engine to breathe more efficiently — resulting in better throttle response, improved towing performance under load, and measurable horsepower gains. For trucks that tow, haul, or spend time on highways regularly, a cold air intake is one of the most cost-effective performance upgrades available.

What is the best cold air intake for a diesel truck?

For diesel trucks, aFe Momentum HD and Magnum Force intakes are among the top-performing options for Cummins, Duramax, and Power Stroke engines. The Momentum HD uses a large enclosed housing with a high-flow filter that delivers maximum airflow at sustained RPMs — critical for towing and heavy-load driving. Pair the intake with a performance Exhaust system for the best combined airflow improvement on a diesel truck.

Does installing a cold air intake void your truck warranty?

Under the Magnuson-Moss Warranty Act, a dealer cannot void your warranty simply because an aftermarket part is installed. They must prove that the specific aftermarket part caused the failure being claimed. aFe Power and other reputable intake manufacturers design their kits to work within safe parameters for each engine platform. Keeping your factory air box and filter stored is a good practice in case you ever need to return to stock for a warranty inspection.

What is the difference between an oiled and dry performance air filter?

Oiled filters like the aFe Pro 5R use a cotton gauze media treated with filter oil that captures finer particles while allowing high airflow. They require periodic cleaning and re-oiling. Dry filters like the aFe Pro DRY S use a synthetic media that requires no oil — making maintenance simpler with no risk of oil contamination on mass airflow sensors. Oiled filters generally flow slightly more air, while dry filters offer easier long-term maintenance.

Does a cold air intake help with towing performance on trucks?

A cold air intake improves towing performance by providing cooler, denser air to the engine under sustained load — reducing heat soak and maintaining consistent power output on long uphill pulls and highway towing. The improvement is most noticeable on diesel trucks towing near their maximum capacity, where the engine demands maximum airflow for extended periods. For the best towing performance gains, combine a cold air intake with a performance exhaust and a Programmers tuner calibrated for towing.
