I have read alot of ads for lsX cars with this LS6 intake. Is it a significant power gain? Does it affect my mpg significantly? I also have 105k on the motor. Too late for such a mod? Sorry for all these questions, I have had the car about 6 months, and I know specs but not much else; and I originally had a 2000 Mustang GT. Fun car, but very different. Sorry if I am flooding you with questions, I do appreciate your help! You have me interested in this intake now, lol.

It might be dead, but im still woundering about the LS6 intake info about power and mpg effects. i just got a T/A so just wounderin since it never got answered

power difference is not seen until 3500rpm between ls-1 and ls-6 manifold (saw on one of gm high techs old comparisons) after that difference was small to about 8rwhp at the top end on a stock car. I got almost 2mpg with headers and a tune.
