Product Description

The K&N 77-9031-1KP High-Flow Intake System is precision-engineered for the 5.7 L V8 Toyota Tundra (2007-2011) and the 5.7 L V8 Toyota Sequoia (2008-2011). By replacing the restrictive factory air-intake path with a high-flow mandrel-bent aluminum tube and a large reusable cotton-gauze filter, this kit allows the engine to breathe easier, putting more clean air into the combustion chamber, which can lead to enhanced throttle response, increased power and a more aggressive intake sound.

Installation is simple and typically can be finished in about one hour with basic hand tools - no tuning required. The polished aluminum finish adds visual appeal under the hood while the washable/reusable filter lowers long-term maintenance costs. While this kit delivers strong performance gains, it's important to check fitment for your specific trim and drivetrain (RWD/4WD) and note that this part is **not legal for sale or use in California on pollution-controlled vehicles**.

Ideal for Tundra and Sequoia owners who want a trusted brand upgrade that combines performance, aesthetics and durability. This kit is especially suited for those who tow or carry heavy loads and want improved engine breathing under load. Because fitment is confirmed only through model year 2011, later years (2012 onward) are **unconfirmed** and should be verified before purchase.
