Rough Country Cold Air Intake for 2012-2021 Toyota Tundra 5.7L | 10546

Overview

Rough Country’s Cold Air Intake System is crafted for the 2012–2021 Toyota Tundra with a 5.7L V8. By routing air from outside the hot engine bay, this setup aims to deliver cooler, denser air to the intake. The larger diameter tube and cylindrical design create a freer path for air flow, which can translate to quicker throttle response and enhanced driving feel compared with the factory air box.

Individual results vary based on vehicle condition, climate, and driving style. Many drivers report a more immediate response when pressing the accelerator, especially during acceleration, merging on highways, or climbing grades. The system uses a premium, reusable air filter that can be cleaned and reused for long-term performance, helping maintain steady airflow and filtration performance over time.

Key benefits you may experience

• Increases horsepower and performance
• Circulates cooler air which is denser and provides more oxygen to the combustion chamber
• Premium, reusable air filter
• Easy at home installation and support provided by RC
• Backed by Rough Country's Limited Lifetime Replacement Warranty

How it works and what you might notice

Cooler intake air lowers air temperature entering the engine, allowing more oxygen to be packed into each combustion cycle. The result can be more confident throttle response and smoother power delivery during demanding conditions. An improved airflow path helps the engine breathe easier at higher RPM, which some drivers associate with a more responsive feel during spirited driving or when towing.

The kit replaces the stock air path with a larger, direct route to the intake while maintaining filtration. This combination aims to balance performance gains with dependable filtration and durability for daily use and road trips alike.

Maintenance, installation, and warranty

The included premium air filter is reusable and straightforward to clean, helping you sustain airflow over time. Installation is designed for at-home DIY enthusiasts, with Rough Country providing installation support if needed. The system is protected by Rough Country’s Limited Lifetime Replacement Warranty for ongoing assurance.

Compatibility and fit

Designed for the 2012–2021 Toyota Tundra equipped with a 5.7L engine, this Cold Air Intake replaces the factory air path to bring cooler, denser air into the combustion chamber and potentially improve drive feel.

In real-world use, the setup is well-suited for daily commuting, highway accelerations, and weekend getaways. It also helps mitigate heat soak during long climbs or hot-weather driving, maintaining a more consistent intake characteristic across varied conditions.
