This Dynamic Air Scoop (D.A.S.) increases direct airflow and velocity into your Challenger's intake system. The cool dense air allows your vehicle to run more efficiently, increasing performance. Inspired by the Challenger SRT Hellcat Air Inlet Duct Design.
Works as it should I feel more power upon hard acceleration not even runs alittle cooler as it shows on my temp Guage. Price I felt was high but I guess you pay for more horse power gains
