My friend got that whole set up for 100$ and plans to install it how much do you think its worth with a stock tune and also will he notice it it is a auto car



Also are there any free mods its a 04 C5 vette

Air ducts on stock cars are worth nothing! We tested one on my head cam motor making 449 rwhp and saw no power change. They are for looks.

IDK dude nothing seems a little far fetched. I was thinking maybe 5horse or so but nothing?? was this on a dyno?

any other people?

Absolutely nothing on a stock car. Coupled with a true CAI like a Vararam, maybe 1hp. Under no circumstances will it be worth 5hp though.

just for looks on a stock car, id say with some type of forced indicution or built motor maybe something small, but not worth your money if your looking for performance. if you wanna see a gain get a dyno tune for 350 bucks, you should see more then 5 with that.

so what your saying is that i should just get the vararam not the combo?

YES!!

Im very pleased with mine!
Went from 13.0's in -2500da to 13.0's in +2500 da! lol

I recommend the Callaway Honker CAI that eliminates that air bridge altogether, and it also moves the MAF closer to the TB for better reads...which is what the GM engineers did on the C6's. I'm happy with mine!
