The K&N 57i Generation II air intake for 2015–2022 Toyota Hilux with the 2.5L L4 diesel replaces the restrictive factory air path with a rotationally molded, non-metallic tube and high-flow filter. K&N says the engineered tube reduces intake restriction and temperature, driving more airflow to the engine. These kits come with K&N’s No-Hassle Lifetime Limited Warranty and are designed for straightforward installation.
