Cold Air Intakes

Go with a dry filter for dusty and off-road conditions for better maintenance and high filtration efficiency. Oiled filters are often chosen for maximum airflow, while dry filters are preferred for easier maintenance and operation in dusty conditions.

The exact number depends on the platform and factory airbox restriction. For reference, certain S&B systems, including some 6.7L Powerstroke applications, have shown airflow increases exceeding 50% during ISO 5011 testing. The enclosed airbox design also helps control inlet temperature during low-speed heat soak in many diesel cold-air intake applications. 

Yes, you can. Nearly all cold air intakes are engineered to have OEM-style MAF sensor ports, preserving factory ECU communication and sensor calibration and adjusting air-to-fuel ratio. If you have a turbocharger, a tuner will allow you to more precisely control the amount of fuel injected to balance it against the added airflow.

No, as factory airboxes on deleted trucks can still do the job just fine. However, after installation, you will enjoy all cold air intake benefits: airflow stability (even when towing) and an improved overall maintenance experience with reusable filters. Some applications may see modest horsepower and torque gains, particularly when combined with supporting modifications and tuning.

Clean or replace dry filters every 15,000-30,000 miles, and oiled filters - every 10,000-15,000 miles. Inspect them in regular intervals to detect damage and check for a dark, dirty appearance. Use screens or water guards to prolong filter service life and ensure performance in varying weather conditions. 

Cold air intake systems are aftermarket devices that replace your truck's factory intake assembly, which draws warm air from the engine bay. They consist of three main parts: an airbox, a filter, and an intake tube. After the replacement, your engine receives a less restrictive airflow path compared to the factory intake assembly, improving horsepower, torque, and throttle response. 

A realistic gain is often up to 5-15 horsepower depending on the platform and supporting modifications, with larger changes showing on engines that already run higher boost and better tuning. The bigger benefit is not peak horsepower. You also improve airflow consistency at sustained load, which can help with power and efficiency on heavy-use diesel trucks.
