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.
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.378.81

Intake was well made. Welding was very clean for aluminum and the pieces were all flush with attachments. Unfortunately the item was mistakenly advertised as "Converts to Short Ram Air", which it only does with extra fabricated aluminum and modifications to the engine bay (2008 Maxima).Was this review helpful for you?

I absolutely love this intake. From the moment I opened the box I knew it was Premium Quality! It is nothing shy of perfect. The installation is so easy that even a first time replacement is done simply. I know this because it was my first time replacing a whole intake system, and it was done just by myself. It only had taken me 1 1/2 hours from start to finish, just follow the instructions. Then, when I finally took it for a drive, the sound caught me by surprise, because it was louder than expected. The best part about my intake though is that I used to get 32 mpg highway. Now, I get whomping 46 mpg highway! Only when I drive it like a town car though. If I race the engine, I only have about a 3-4 mpg increase. This intake was placed on a 2011 Nissan Altima 2.5 S Sedan.Was this review helpful for you?

I first bought the SP1900 after being told it will fit Turbo model. Then had to buy SP1902 which does. Living in UK this took a long time to get the right part.
