Rough Country Cold Air Intake for Chevy Silverado & GMC Sierra 1500 (2014-2018) 5.3L/6.2L – Increases Horsepower, Towing Power & Acceleration

What This Intake Actually Improves

The stock airbox restricts airflow and pulls in warmer air. Rough Country replaces it with a high-flow system designed to increase efficiency and performance.

• Improved airflow for better engine breathing

• Increased throttle response in daily driving

• Enhanced towing performance under load

• More aggressive intake tone when accelerating

• High-flow air filter for better air volume

This is one of those upgrades you actually feel—especially in a full-size truck.

Gain increased horsepower and throttle response while protecting your engine from harmful particles and debris with Rough Country’s Cold Air Intake System. By moving the air filter away from the heat of the engine compartment, it delivers cooler, oxygen-rich air directly to the combustion chamber.

Real Benefits for Trucks (Not Just Sound)

On a Silverado or Sierra, airflow upgrades aren’t just about noise—they directly impact how the truck performs under stress.

• Better towing response when pulling heavy loads

• Improved acceleration for merging and passing

• More consistent power delivery under load

• Reduced engine strain during heavy use

Because let’s be honest—these trucks aren’t just cruising to Cars & Coffee. They’re working.

This optimized airflow increases engine efficiency, allowing your truck to perform at its greatest potential. The cylindrical design and large-diameter tubing offer far superior airflow compared to factory air filters enclosed in a box.

Each intake kit features a premium, reusable multi-layered air filter that’s easy to clean, ensuring long-lasting performance and providing additional engine protection from dirt and debris. Installation is quick and simple, providing an instant performance upgrade. Engineered for heavy-duty use, our cold air intake system is built to withstand extreme and demanding conditions often found under the hood. With a Limited Lifetime Warranty, the Rough Country Cold Air Intake is an ideal choice for truck owners looking to maximize engine power and efficiency. Note: Does not fit eAssist models.

High-Flow Filter + Heat Management

Rough Country’s system focuses on both airflow and temperature control:

• High-flow reusable air filter improves intake efficiency

• Heat-resistant design helps reduce hot air intake

• Durable construction built for truck use and conditions

Because under-hood temps in a truck—especially when towing—are no joke.

Boost Horsepower and Throttle Response: Increase engine power and throttle sensitivity with Rough Country’s Cold Air Intake kit. It delivers cool, oxygen-rich air to increase HP, torque, acceleration, and overall engine performance.
Optimized Airflow for Cooler Combustion: Delivers cooler, denser air to the engine for better combustion and overall performance. Its cylindrical design and large-diameter tube improves airflow over stock air filters.

Daily Driver + Work Truck Approved

This intake is ideal if you want:

• Better throttle response in everyday driving

• Improved performance while towing or hauling

• A deeper, more aggressive engine sound

• A reliable, bolt-on upgrade

It adds performance without sacrificing the practicality you bought the truck for.

Durable, High-Quality Construction: Built for heavy-duty driving, this intake system uses a high-density polyethylene (HDPE) tube for increased airflow and includes a molded heat shield to protect intake air from engine heat.
Reusable High-Performance Air Filter: Includes a premium multi-layer air filter that’s easy to clean and protects your engine from harmful particles and debris.

Why This Upgrade Makes Sense

For a full-size truck, airflow upgrades actually matter more than people think. You’re moving more weight, asking more from the engine, and dealing with higher loads.

The Rough Country Cold Air Intake helps your Silverado or Sierra handle all of that more efficiently—while also making it sound like a proper V8 should.

And if your truck still sounds stock when you hit the gas… yeah, it’s time.

Simple to Install: Installs in a snap for an instant increase in performance, backed by Rough Country’s limited lifetime warranty.
