Rough Country Cold Air Intake for 5.3L & 6.2L V8 — Bolt-On Performance with Washable High-Flow Filter

Rough Country Cold Air Intake is a bolt-on performance intake system that supplies cooler, denser air to 5.3L and 6.2L engines for improved throttle response and horsepower.

If your goal is a durable, no-fuss upgrade that helps your V8 breathe better, this Cold Air Intake is built to replace the restrictive factory airbox with a free-flowing design and a washable high-flow filter. The system relocates the air source outside the hot engine bay, adds large-diameter tubing, and uses a reusable cylindrical element to balance filtration and airflow for daily driving, towing, and off-road use.

How does this intake increase engine performance?

By moving the filter away from engine heat and using wide-diameter tubing, the intake delivers cooler, denser air to the throttle body. Cooler air carries more oxygen per volume, which helps the engine create stronger combustion events and improves throttle response under load.

• Relocated filter draws outside air instead of hot underhood air.
• Large-diameter intake tube reduces airflow restrictions.
• High-flow cylindrical filter balances filtration and maximum airflow.

Is installation complicated or does it require permanent modifications?

Installation is intended to be straightforward and bolt-on using factory mounting points—no cutting or permanent changes are required. The design lets you return to the stock configuration if needed, and most installations can be completed with common hand tools in a typical driveway or garage.

• Uses factory mounting locations for a secure fit.
• No cutting, welding, or permanent underhood modifications.
• Typical install time is short; basic mechanical experience recommended.

What maintenance does the reusable filter need?

The included high-flow filter is washable and re-oilable, allowing repeated use without buying replacement paper elements. Regular cleaning depends on driving conditions—more frequent service for dusty off-road use, less often for paved-road commuters.

• Clean and re-oil the filter when performance or inspection indicates dirt buildup.
• Optional pre-filter bag is available for dusty or sandy environments.
• Routine checks ensure long-term airflow and filtration performance.

Are there fitment or legal restrictions I should know about?

This Rough Country Cold Air Intake is designed specifically for 5.3L and 6.2L engines and will not fit vehicles equipped with the eAssist (ECO Hybrid) package due to underhood differences. It is not for sale in California or other states that follow California’s aftermarket air emissions regulations.

• Fits only vehicles with 5.3L or 6.2L engines.
• Not compatible with eAssist (ECO Hybrid) models.
• Not legal for sale in California and certain states adopting similar rules.

Who is this for? Rough Country’s Cold Air Intake is aimed at truck and SUV owners with 5.3L or 6.2L engines who want a durable, easily installed airflow upgrade that improves throttle response, supports towing and off-road use, and reduces recurring filter costs. It’s a good fit for drivers who prefer a reusable performance filter, need a system built to withstand heat and vibration, and want a limited lifetime replacement warranty for long-term confidence. If you often drive in extremely dusty conditions, consider adding the optional pre-filter bag to extend cleaning intervals and protect the washable element.
