Better Flow for More Power. A simple way to increase the power and performance of your 2011-2023 5.7L Hemi V8 Challenger is by installing a SR Performance Cold Air Intake. By replacing your Challenger's restrictive stock factory intake with a high flow filter assembly you will see and feel a noticeable increase in rear wheel horsepower and torque. This SR Performance Intake not only improves airflow for an increase in power, but it will also add a show winning appearance to the engine bay with its brightly polished aluminum intake tube.No Tune Required. SR Performance engineered their Cold Air Intake to improve the performance of your V8 Challenger without the need of reprogramming your computer. By utilizing flow dynamics, this Intake will increase power using the original factory tune. Even though a re-tune is not required for operation, We recommend a custom tune to reprogram the vehicles computer (ECU) to get the best possible performance from this Cold Air Intake.Reusable Air Filter. The included high flow air filter effectively filters out power robbing particles with its multi layer design. The specially treated media creates a sticky surface to capture microscopic contaminants before they can enter your Challenger's engine and do harm. Seeing that the filter is reusable there is no need to buy a new filter every few thousand miles. You can just clean the filter, re-oil it, and reinstall - saving yourself money in the long haul.Simple Bolt-on Installation.
