07-13 Tundra 5.7L Air Intake System

The K&N Engineering 07-13 Tundra 5.7L Air Intake System (part number 57-9031) is a cold-air induction upgrade engineered to increase airflow to your Toyota truck's engine while maintaining reliable, street-legal operation. This reusable, oiled-filter design replaces the restrictive factory air box with a tuned intake tract that draws cooler ambient air directly into the engine, improving volumetric efficiency and throttle response across the RPM band.

The 57 Series FIPK (Fuel Injection Performance Kit) configuration features a black plastic intake tube and K&N's signature reusable cotton-blend filter element, which captures airborne contaminants while allowing high flow rates compared to OEM paper alternatives. The larger filter surface area and smoother intake path reduce intake velocity restriction, which translates to measurable gains in responsiveness during acceleration and towing. The oiled filter design requires periodic cleaning and re-oiling—a simple maintenance task that extends the filter's lifespan indefinitely and maintains performance consistency over thousands of miles.

This system is purpose-built for 2007–2013 Toyota Tundra full-size trucks and Toyota Sequoia models equipped with the 5.7L V8 engine. Owners seeking genuine performance gains without complex tuning or engine modifications benefit from the straightforward installation and compatibility K&N provides. The intake system delivers noticeable improvements in engine sound and responsiveness, making it a foundational upgrade for truck owners who tow regularly, drive off-road, or want to maximize the potential of their 5.7-liter platform.
