Default Intake Manifold Swap

hey guys i just had a question on whether it's worth it to put in a stock STI intake manifold on a wrx.

I have a 06 WRX limited and i'm planning on putting on a stock STI Turbo, stock STI injectors and a stock STI TMIC, is there any worth to the engine to invest in a stock STI intake manifold?

what are the differences between the stock WRX and STI manifolds?

they're identical internally, and it wont work without customizing the throttlebody flange.

Not worth your time or money. I'm almost positive the main difference is the color.

If you found a TGV-less JDM manifold, that would probably be worth it.

the STI TGV's are different also but basically all you will end up with is a red manifold.

everything else is the same.

Do the turbo though! great daily driver mod for real power

will i need to get a tune? bc if i do i'm probably gonna throw on the TMIC before the turbo and keep the TD04 on for a little bit before i have time to get a tune.

and if i do that i heard the Y pipe for the STI turbo wont reach to the TD04, is that true or will it reach?

get a tune no matter what you change. these aren't mid '80's cars anymore. you waste gas if you don't get a tune, and make less power than you're hoping for(tune=power on newer cars)

same manifold, and not worth sourcing a TGV-less manifold as you can delete them on yours for free! lol
