    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. All kits include a heat shield that seals against the hood and isolates the filter from engine heat, or the Injen Powerflow Box. The Powerflow Box incorporates an EA Nanofiber dry air filter as well as a velocity stack and air stabilizer, and a cold air inducer, all contained in an aluminum housing to protect the filter from heat. The reduction in air intake temperature results in a cooler, denser air intake charge and even more horsepower. So, instead of power-robbing hot air squeezing through a restrictive air filter and intake duct, your engine is taking in huge quantities of cool 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.

    Nice Upgrade!
    We recently purchased a travel trailer, so I was looking for a low cost solution to get a few more horses out of my old truck. We have definitely noticed the increase in power, both towing and just normal driving. Sounds great too! Would definitely recommend this product!

    Awesome!!!
    This is awesome. I installed this on a 2005 Nissan Titan LE and it looks great, and sounds great when you get into the throttle. There is a noticeable throttle response difference on hard access, and it looks amazing when you pop the hood. The installation was super easy, however I did have to modify the intake manifold cover slightly to fit properly. No big deal.
