Don't want to start a argument but I just pulled off the AMG/SRT6 air boxes and re-installed the factory engine cover/intake prior to taking mine into the dealer for the first service/oil change. Car was quieter, smoother at low revs but SLOWER. Difference was startling so I put the AMG set-up right back on. It revved faster, pulled harder and was louder. I'll take the stock set-up to the strip with me when I go and get e.t./MPH number to confirm.
I really don't think this is just a subjective impression. Dynos cay vary But the quarter mile doesn't lie. I'll post numbers as soon as I get 'em !
