INJEN PF Series Power-Flow Air Intake Systems

Injen PF Series Power-Flow intake systems deliver unmatched power gains. These Injen Power-Flow cold air intake systems are engineered to the highest standards, utilizing the latest technology available. Incorporating Injen's own patent-pending MR Technology proves that the Power-Flow series intake systems are the world's first tuned intake systems on the market! The Injen Power-flow intake systems ensure the highest horsepower and torque gains within the safe factory air/fuel ratio limits.

Injen Power-Flow intakes deliver a blast of oxygen at the perfect moment, for blazing combustion and gut-wrenching power output. Injen Power-Flow intakes put your motor on a steady diet of colder, richer oxygen. The process starts with the high-flow air filter's integrated air inducer, air stabilizer, and velocity stack. Fresh air is drawn in, smoothed out, and pressurized. From there, the oxygen flows through the Mega Ram-tuned pipe, where it is released to the mass airflow sensor at calculated intervals. Each intake kit goes through a rigorous dyno-testing process, and is fine-tuned to unleash ferocious performance across the rpm spectrum.
