Fitment: (2018+) Polaris RZR RS1. The Agency Power High Flow Air Intake System for the Polaris RZR RS1 is a great upgrade to help improve air flow from the intake to the engine. Not only does the intake gain very respectable horsepower, it also improves the drivability through the entire RPM range. The air intake kit features a roto-molded plastic tube design that faces towards the rear of the vehicle. Each intake includes a Polaris mesh inspired cross brace and our high flow dry filters. The new intake tubes and filters replace the factory intake system that runs to the roof of the RS1. This new design aids in increased air flow while filtering out more particulates than stock. As tested on the dyno, Agency Power saw a peak gain of 8 horsepower from just the air intake and an 11 horsepower gain with our custom VR Tuned ECU Flash. The easy modification of adding the Agency Power Air Intake System will help your Polaris RZR RS1 breathe better for greater performance. This simple upgrade is a must have for those running aftermarket roll cages and need an air intake solution. The Agency Power cold air intake has been engineered from the ground up to be a direct replacement for the factory Polaris RZR RS1 intake. Starting from 3D printed components and real world desert testing, each part of the intake has been meticulously thought out to provide performance, longevity, and reliability. The custom high flow Agency Power air filter features a blue mesh design with AP logo end cap. This mesh is made up of synthetic nano-fibers. The dry filter does not need to be oiled as its media has sub-micron diameters and small inter-fiber spaces which result in more contaminants being captured. This filter is reusable allowing you to easily clean it between rides. To further provide the best air quality for off-road use, Agency Power has created an optional custom Outerwear brand pre-filter cover made specifically for the intake filter which is included in the kit.
