Construction & Design

Constructed from high-quality 6061-T6 aluminum, the intake tubing is both lightweight and exceptionally durable, offering excellent resistance to heat and corrosion. The polished finish not only enhances the engine bay’s appearance but also aids in dissipating heat to keep intake air temperatures low. The SuperNano-Web dry air filter features a synthetic media that balances high airflow with outstanding filtration efficiency, ensuring your engine breathes clean air while protecting vital components.

The intake system’s design strategically positions the air filter away from the engine’s heat sources, drawing in cooler ambient air to improve combustion efficiency. This thoughtful engineering reduces intake air temperatures, contributing to enhanced power output and throttle response.

Performance & Sound

Dyno testing confirms that the Injen Polished PowerFlow Intake System delivers measurable performance improvements, with gains of up to 11 horsepower and 13 lb-ft of torque. These enhancements translate to quicker acceleration and a more responsive driving experience. Additionally, the intake produces a noticeable, aggressive engine tone under full throttle, adding to driving excitement without being intrusive during everyday use.
