LS6 intake is a great mod especially if you do a cam in the future.

with heads cam there is a definate gain. even on stock heads, even though some people would have you believe otherwise

just dont forget the new coolant tubes if you get it and the block of plates for your headers after removing your egr system.

so far, 12.8 on a hot humid day. So 12.5 is realistic on a cooler dry day.

my car always varies 2 - 3 tenths, 3 mph depending on weather.
