The Injen PF Series Power-Flow Cold Air Intake System is a high-performance induction solution engineered specifically for the 4Runner V6-3.4L. Utilizing Injen’s patented MegaRam (MR) Technology, this system is precision-tuned to maintain optimal air-fuel ratios while delivering substantial performance increases. The intake is constructed from mandrel-bent 6061-T6 aluminum, providing a smooth, high-velocity path for air to reach the engine. Equipped with an oversized SuperNano-Web dry air filter and a massive cast aluminum Power Box with pre-filter screens, this system ensures elite filtration and maximum oxygen density for improved combustion and throttle response.
