Injen’s all new Evolution series sealed cold air intake system for the 2019-2021 Chevrolet Silverado 1500 and the 2019-2021 GMC Sierra 1500 is unmatched in the aftermarket. The EVO7104 is a sleek intake kit that practically drops-in by itself and provides unparalleled looks under your hood. On top that of that beautiful housing is our Clear-View window for easy filter inspection. This window has an eye-catching red stripe with a white Injen logo that really pops when you open your hood. The EVO7104 housing encloses an Injen SuperNano-Web dry air filter utilizing our patented Twist-Lock technology for a simple install and clean looks. Injen’s EVO7104 comes with all necessary hardware to provide a simple and fast installation. No cutting or drilling required for an easy installation process that does not require aftermarket tuning for exceptional HORSEPOWER and TORQUE GAINS straight out of the box.
When it comes to durability, Injen’s Evolution series can’t be beat! Some of our competitors use an inferior HDPE linear polyethylene to mold their intakes. HDPE is cheap for manufacturing but doesn’t come close to the strength and durability of XLPE polyethylene. The XLPE that Injen uses has 20 times the environmental stress crack resistance of HDPE, 10 times the molecular weight of HDPE, and 5 times the impact and tensile strength of HDPE. In other words, Injen’s Evolution intake systems are built tough and designed to last!
Cross Linked XLPE Roto-molded Housing:
The one-piece sealed housing utilizes the all-new Injen Twist-Lock System to securely attach the SuperNano-Web Dry air filter in place which eliminates the use of unnecessary parts and provides one of the simplest installations available. The EVO7104 housing also sports the all-new Injen Clear-View badge for a cleaner more aggressive under hood appearance.
Roto-molded Intake Tube:
The EVO7104 Evolution Air Intake System uses a custom designed and dyno-tuned, intake tube to produce huge power gains while retaining an OE quality fit. Injen also incorporated their internal MegaRam (MR) technology for safe and effective power gains without the fear of check engine lights.
SuperNano-Web Dry Air Filter:
"That’s massive!” is all you will hear about this SuperNano-Web Dry air filter that is included with the EVO7104 cold air intake system. This filter has been uniquely designed to work with the Injen Twist-Lock System. Using our Twist-Lock technology has allowed our engineers to use the largest filter possible for this application, which increases the available air volume - resulting in added power while keeping the installation process quick and simple.
From the Stainless Steel Band Clamps with an inner protective liner to the reinforced automotive grade silicone coupler, every aspect is covered for a perfect and secure fit.
Make it easy! By designing this kit in a 3D workspace, you’re ensured a quick and easy installation that not only increases the power output of your engine, but also provides a clean and powerful look that others see every time you pop your hood.
Clean and simple, NUMBERS talk! Injen has put in the time and diligence to stand behind our performance data. We put in the time to test and prove that we have developed a superior kit for your 2019-2021 GM Silverado/Sierra 1500 truck. After hours of designing and dyno testing, Injen is proud to say that the EVO7104 Evolution Air Intake system puts down numbers of up to 13 additional horsepower and 14 Ft.-lbs. of torque.
