Dodge Challenger & Charger Hellcat SRT Performance Air Intake Cleaner Box - Mopar OEM Replacement Part - Perfect for Racing & Street Performance Upgrades

Bought this for my 2021 Challenger and also purchased the attachment that came separately…The lower fit fine however the attachment didn’t fit properly and despite me having to trim it off the angle didn’t work well for me so I used a lot of gaffers tape to seal it up.After getting it to work I took my car for a ride and immediately notice there was less power in the low end and it lost some of the torque too…The problem I ran into is that whenever you add more air to the intake the fuel management system needs to be flashed to accommodate this which I didn’t do because the sellers are saying you don’t need to do this, they are wrong.I ended up removing it and replacing the original intake back in my vehicle and wouldn’t you know it, my car ran normal with tons of low end torque.This product will work well as long as you or a dealer flashes the vehicle’s fuel management system and calibrates the fuel/air flow to accommodate the changes…
