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.

Looks Great and Performs Great
The intake is an easy, though not cheap, way to improve your acceleration on these slow and heavy Tahoes. Can't say much on the sound it makes, since I can't hear it with my dual exit exhausts. What I can say is this - definite improvement over stock. Significant improvement on acceleration. Gas MPG on my truck went up 8 on average when driven lightly. Highest HP-TQ-MPG gains are made in winter temperatures, and unfortunately, it suffers noticeably in summer, since the unit is susceptible to heat-soak because of the aluminum material. Especially for me here, in Vegas, where it can get as hot as 120 F. Best part for me is the fact that CARiD.com sells this unit with an Amsoil Ea Air Filter. Same air filters used by the U.S. Army. Great way to extend engine life by filtering those tiny abrasive microscopic particles. Look it up if you don't know what I'm talking about.

Not a Cold Air Intake
The air intake system looks great and is fairly easy to install, but after a short period of time, the chrome polished pipe gets very hot.
