$ 336.96
The engineered weapon of choice with a touch of class! Injen Technology continues to remain on the cutting edge with the invention of the first functional composite airbox, ViT valve, air plenum and stainless steel pre-filter screen. The power on demand generated from this explosive combination will satisfy anyones thirst for speed and power with up to an additional +11.6hp and 28ft-lbs of torque. Key Features: MR Technology (Tunes intake to factory Air/Fuel Ratios) Web Nano-Fiber Dry Filter Reusable Mandrel-Bent Prime Aluminum Alloy Hand Crafted in the U.S.A Injen/AMSOIL Ea Air Filters represent a major breakthrough in filtration technology. The revolutionary nanofiber technology used in Injen/AMSOIL Ea Filters captures more dirt, holds more dirt and allows better air flow than conventional air filters. Injen/AMSOIL Ea Filters improve engine performance and help engines last longer. Absolute Efficiency Injen/AMSOIL Ea Air Filters are the most efficient filters available to the Diesel truck market. Ea Air Filters synthetic nanofiber media removes 5 times more dust than traditional cellulose filter media alone and 50 times more dust than wet gauze filter media. Injen/AMSOIL Ea Air Filters have a service life of 100,000 miles or four years, whichever comes first. Better Air Flow Injen/AMSOIL Ea Air Filters allow more airflow than filters that use cellulose media alone. Cellulose fibers are larger than nanofibers, and have larger spaces between the fibers, causing contaminants to load in the depth of the media and plug the airflow path, which results in higher restriction and less capacity. The synthetic nanofibers in EaA Filter media have submicron diameters and small interfiber spaces, which result in more contaminants being captured on the surface of the media and lower restriction. More Capacity Injen/AMSOIL Ea Air Filters hold up to two and a half times more contaminants than cellulose air filters. Since the nanofibers in the media are so small there are more pores per square inch, allowing for higher dirt-holding capacity and lower pressure drop when compared to cellulose filter media alone. Thinner media fibers produce more uniform pore size distribution, improving the filters overall quality and ability to capture and retain particles. Testing shows that Ea Air Filters hold 15 times more contaminants than a wet gauze type filter. Cleanable - Longer Life When cleaned according to Injen/AMSOIL specifications and used in normal service, Injen/AMSOIL Ea Air Filters are guaranteed for 100,000 miles or four years, whichever comes first. EaA Filters remain effective for 25,000 miles or one year before requiring cleaning. This coincides with the Injen/AMSOIL 25,000-mile/one-year motor oil drain interval, adding even more convenience for motorists by consolidating routine maintenance. (See below for cleaning instructions.) Cleaning EaA filters should be cleaned every year or 25,000 miles, whichever comes first. Carefully remove the filter from the housing. Clean the housing with a shop towel, being careful not to knock contaminants into the air inlet. Service Life Injen/AMSOIL Ea Air Filters are guaranteed for four years or 100,000 miles, whichever comes first. The guarantee applies only if the filter has been serviced according to Injen/AMSOIL recommendations. In off-road, frequently dusty or other severe duty applications, clean and change more often as determined by operating conditions or as indicated by restriction gauge.

Injen Technology has taken extra measures to ensure that you get what you paid for: extra power, optimum throttle response and quality. Injen has in-house capabilities for bending these tubes. Available in black for stealth look and polished intakes for those who are conscious of looks along with horsepower gain. With the use of 1/4" thick 6061 T-6 aluminum and precise CNC machined brackets and adapters, you are guaranteed an exact fit every time. Not only does Injen dedicate themselves to making precise crafted cold air intakes, they also back it with a limited lifetime warranty to ensure a quality intake for years to come.
