K&N 2010 Toyota FJ Cruiser 4.0L-V6 / 2010 4 Runner High Flow Performance Kit

K&N Engineering is well-known for its high-flow air filters and performance intake systems. This specific cold air intake kit, part number 77-9034KP, is built for your 2010-2024 Toyota 4Runner or 2010-2014 Toyota FJ Cruiser with the 4.0L V6 engine. It's designed to replace your restrictive factory airbox and intake tubing, allowing your engine to breathe more freely.

The system features a mandrel-bent aluminum intake tube, which helps maintain consistent airflow diameter throughout the intake tract. This is paired with K&N's signature washable and reusable High-Flow Air Filter, made with oiled cotton filter media. This oversized, conical filter is designed to go up to 100,000 miles between cleanings under normal highway driving conditions. A custom heat shield is included to help block hot engine bay air from entering the intake, ensuring cooler, denser air reaches the engine for improved performance. K&N guarantees an increase in horsepower and torque with this system.

Installation is typically straightforward and can often be completed in under 90 minutes, with no special tools required beyond basic hand tools. This kit is backed by the K&N Million Mile Limited Warranty. Please note that this intake system is not legal for sale or use in California due to emissions regulations.
