Just thought I'd add my $0.02 to the thread, as I've just finished test
driving my SRT-6 after having installed the SL55 intake I got from LET.
Just my opinion, but I'd say I've added a whole lot of torque, and my
acceleration appears to have been positively affected. I can hear the
difference in the sound. Whereas previously when I planted my right
foot to the floor I'd hear the air intake make its whine, now it sounds
like there's a tornado under the hood. I really am impressed with the
apparent (perceived) gain this modification has added. It seems that
with more air, the engine has really come alive.

I would recommend this modification.
