Product Description

The K&N 77-9042KP Cold-Air Intake System is engineered specifically for the 3.4 L I6 engine in the Toyota Tundra (2022-2025) and Toyota Sequoia (2023-2025), in both RWD and 4WD configurations. By replacing the restrictive factory intake with a smooth mandrel-bent aluminum tube and an oversized reusable cotton gauze filter, this system allows the engine to breathe more freely, improving airflow, intake temps and throttle response. The dyno-tested performance gains of approximately +18.4 HP and +17.9 lb-ft of torque reflect measurable improvement in real-world conditions.

Installation is straightforward and designed to be completed in about an hour using common hand tools - no ECU tuning or major modifications required. The polished tube adds under-hood style while the washable filter offers long service life and minimal maintenance costs under normal usage.

Please verify your exact engine size (3.4 L I6) and drivetrain (RWD/4WD) before ordering. Coverage is confirmed through model years 2025 for both vehicles; however, always check for your specific trim and region. Note that this kit is **not legal for sale or use in California** on pollution-controlled motor vehicles, so confirm local regulatory status before purchase. Ideal for Tundra or Sequoia owners seeking a high-quality performance upgrade from a trusted brand.
