Rough Country Cold Air Intake for 3.8L — Bolt-On with High-Flow Reusable Filter

Rough Country Cold Air Intake is a bolt-on performance system that delivers cooler, denser air to your 3.8L engine for improved throttle response, horsepower, and fuel efficiency.

Designed for drivers who want a dependable performance upgrade without cutting or permanent modifications, this intake replaces the restrictive factory airbox with a free-flowing tube and high-flow reusable filter. The result is increased airflow to the engine, quicker throttle response, and a stronger feel during acceleration — whether you’re towing, commuting, or tackling off-road trails. Built from durable materials and backed by Rough Country's Limited Lifetime Replacement Warranty, the system is engineered to withstand daily driving and harsh environments.

How does this intake improve engine performance?

The intake improves performance by supplying the engine with cooler, denser air and reducing intake restriction. That allows combustion to be more efficient, helps the throttle respond faster, and can translate into noticeable gains under load and during acceleration.

• Relocates the filter away from hot engine bay air for cooler intake temperatures.
• Large-diameter intake tubing reduces airflow bottlenecks versus the stock airbox.
• High-flow cylindrical filter increases volume of air available to the engine.
• Optimized flow path supports better throttle response and acceleration feel.

Is the filter reusable and how do I maintain it?

The system includes a washable, high-flow performance filter that’s designed for repeated service cycles. Routine maintenance is simple and cost-effective: clean, re-oil, and reinstall the filter to restore peak airflow and filtration performance.

• Wash the filter with a compatible cleaner and rinse thoroughly.
• Allow to dry completely before applying filter oil evenly.
• Reinstall using the included clamp or mounting hardware for a secure fit.
• Optional pre-filter bag available for dusty or sandy environments to extend cleaning intervals.

How difficult is installation and will it require vehicle modifications?

Installation is designed to be straightforward and uses factory mounting locations, so no cutting or permanent modifications are required. Most technicians or experienced DIYers can complete the swap with common hand tools and basic mechanical knowledge.

• Bolt-on design aligns with factory mounts for a secure fit.
• No permanent trimming, drilling, or adhesive modifications needed.
• Clear instructions and all necessary hardware included in the kit.
• Typical install time is significantly less than custom or enclosure-modifying kits.

What materials and protections help this intake last?

The Cold Air Intake is constructed from robust materials chosen for durability under heat, vibration, and off-road stress. Components resist common under-hood wear so the system continues to perform mile after mile.

• High-quality intake tubing resists heat deformation and vibration.
• Durable filter media built for repeated wash-and-reuse cycles.
• Corrosion-resistant clamps and brackets maintain secure connections.
• Optional pre-filter bag adds debris protection in harsh conditions.

Who is this for: The Rough Country Cold Air Intake is ideal for owners of vehicles equipped with a 3.8L engine who want a reliable, maintenance-friendly power upgrade without permanent vehicle alterations. It suits daily drivers seeking better throttle response, towing drivers who need stronger acceleration under load, and off-road enthusiasts who want durable components. Note: this intake is designed exclusively for 3.8L engines and is NOT for sale in California or other states that have adopted CARB regulations.
