On an Evo 7, what is this NACA duct for?

 

That is blocked off on the street car. However, it's functional on the rally car and it feeds cold car to the air intake box...

 

I'm assuming 'opening' it is a common mod for 7 owners Seems like it would roughly line up with the airbox on the 7.

 

Negative. It lines up exactly with the fuse box
Won't really do much good to open it up unless you add a duct to the air intake.

 

Duh just looked and saw that. For some reason I though the 7 airbox was farther back than our 8s; oh well

 

Survey SAYS! NOTHING!

 

thats a nice looking car!!!
looks familiar

It lines up w/ the fuse box. I did remove the metal plate that was blocking it. Only 2 screws.....It now goes dirrectly to my hks blow off valve w/c is positioned right after the fuse box. You can hear the blow off more....that about it. I was also wondering what its really designed for. Doesnt make sense thou.

 

OnlineAlias - where do you mount your number plate on that car? Forgive the newbie question, but I thought Evo 7s and 8s had the offset number plate mount unless you got a JDM GTA-spec bumper?

I love the clean no-plate look - is it an aftermarket bumper?

 

Nope thats the stock bumper. Mine is the same way because the dealer didnt install the ofset bracket for the license plate. It was in the trunk still pacaged up so I would say they all come without the bracket and the dealers install them. BTW I live in Colorado

 

Did you install the bracket?

I have spoken to the dealer down here enquiring as to whether I can order a GTA-spec bumper so that I can mount the plate in the middle - IMHO it just looks better, less 'rice boy'-ish - even though less airflow will get to the intercooler.

Our plates in Australia are more slimline than US plates, so its not really an issue if it CAN be mounted in the middle on a stock Evo 8 bumper, would save me ordering another one.

 

Good thread. I had often wondered what the Evo 7 NACA duct was for too.

 

Not my car, just an example...pretty one tho...
