Product Description

The K&N 77-9034KP Cold-Air Intake System is engineered specifically for the 4.0 L V6 versions of the Toyota 4Runner (2010-2024) and Toyota FJ Cruiser (2010-2014). By replacing the factory intake path with a smoother mandrel-bent aluminum tube and an oversized, washable cotton gauze filter, this kit reduces airflow restrictions, allows the engine to breathe more freely and delivers measurable performance gains - namely an estimated +11.13 HP and +13.2 lb-ft of torque.

Installation is straightforward and designed for the enthusiast or DIYer; the kit uses factory mounting points and includes all required hardware. The polished tubing enhances under-hood aesthetics while offering improved airflow and consistent durability. While many factory systems rely on restrictive air boxes, this system opens the airflow path without sacrificing filtration quality or long-term serviceability.

Please verify your exact model, drivetrain (RWD or 4WD) and engine size (4.0 L V6) when ordering. Note that this kit is **not legal for sale or use in California** on pollution-controlled vehicles, so verify local regulations if shipping to or operating the vehicle in California or a CARB-regulated region. This upgrade is ideal for 4Runner or FJ Cruiser owners seeking reliable performance improvements, improved engine sound and enhanced under-hood style - all from a trusted brand.
