        Injen FAQsInjen About

        • A large air filter and large diameter air intake tube to maximize air volume
        • Uses the patented MR Technology tuning process to ensure the air/fuel ratio is within optimum limits
        • Custom designed and engineered to deliver maximum power for each specific vehicle
        • Improves acceleration and fuel economy

        • Backed by a Limited Lifetime Warranty
        • Proudly manufactured in the USA

        The big "deep breathing" engine in your high performance car, truck or SUV needs a PF Series High-Flow Air Intake System to unleash all of its power. The system starts with a large EA Nanofiber dry air filter, installed in place of the restrictive factory airbox. The large increase in filter area over the stock airbox filter results in a huge increase in airflow and a greater capacity to capture and hold dirt.

        The increased airflow continues with a free-flowing mandrel-bent or cast aluminum intake tube in place of the factory air path. The use of a casting was necessitated on some applications to maximize the airflow and for fitment reasons. So, instead of power-robbing hot air squeezing through a restrictive air filter and intake duct, your engine is taking in huge quantities of air surging through free-flowing tubing. The result is increased horsepower and torque, and improved performance.

        MR technology

        But unlike other air intake systems, Injen's patented MR (Mega Ram) Technology attains this increased intake airflow and performance while maintaining a safe air/fuel ratio. Injen steps down the diameter of the intake tube where the Mass Air Flow (MAF) sensor mounts, enabling the sensor to detect airflow within established parameters. The engine control computer can then maintain the proper air/fuel ratio and optimize horsepower and torque. Simply put, MR Technology tunes the intake system to avoid the necessity of recalibrating the MAF sensor, and prevents your engine from running too lean or too rich. With MR Technology, Injen created "The World's First Tuned Intake System", delivering optimum performance with a factory safe air/fuel ratio.

        The PF system is carefully engineered, with CNC machined brackets and adapters, to ensure an exact fit. Installation can be accomplished with simple hand tools and everything necessary for installation is supplied, including comprehensive instructions. The PF Series Air Intake System is backed by a Limited Lifetime Warranty.

        Injen Technology Company, Ltd., based in Pomona, California, was formed as a sister company to RD Metal Works in 1998, to utilize the experience and design capabilities that RD Metal Works had gained designing and manufacturing air intake kits for leading air filter and intake manufacturers. Since that time, the company has made it a point to stay at the forefront of performance technology, continually setting new standards for quality and improving their engineering and manufacturing capabilities. This enables Injen to regularly introduce new, cutting edge products to market and has required the company to continually expand to meet the demand for those products. Today, Injen continues to set the industry benchmark for innovation, styling and technology.

        The product fits perfectly and was delivered on time. One end of the polished tube was dented, but I easily repaired it. The truck sounds and preforms great !

        Shipped fast. Looks impressive at a good price. Install only took 15 minutes on 2010 Dodge. Haven't had it on very long or on any trips yet, but it appears to be better gas mileage.
