Hey kids- just put my hood scoop screen in this weekend- it looks great- if anyone is planning to do this, wear gloves when working with the aluminum- I got a few jagged pieces stuck in my hands and they were like trying to remove fish hooks- sweet looking (and cheap) mod though!

There's a nice discussion on this also over on Edmunds Townhall.

The cheapest way to go to Home Depot and buy some aluminum mesh and cut it to size.

Uh huh- that's what I did- but once you cut it, watch out for the rough edges of the aluminum- Home Depot had it for, like, $4 and change.

I don't feel it's too restrictive at all- no power loss or anything, and if it keeps my intercooler safe, I'll take a little less airflow- I was thinking of adding an air diverter, but I'mnot sure if this is a gimmick- anyone wanna chime in? Jedi

sounds real gimmicky to me. someone show me a smoke test of our current setup, and how inneficient it is, then i'll consider.

I know what you mean- the stock scoop takes in the air and then the intercooler is sealed against the inside of the hood- so where's the air gonna go? Right to the intercooler, it's not like the air gonna go in the scoop and make a loop and go back outside of the car- I'll steer clear of the air diverters.

You are DEFINITELY restricting air flow with a scoop mesh. I have one on the STI scoop because I didn't like the way the diverter looked when the hood is closed. I may have to remove the diverter and the screen for maximum performance speciallly if I go to the track. Plus that thing is heavy and you'd think you have a carbon fiber hood almost with that thing off.

Air dividers are somewhat effective, but did you guys see the price on those? Damn expensive! I think Ill stick with not getting one.

Actually I find it hard to belive that 1/4" diamond pattern expanded aluminium is significantly restrictive or heavy, though i've no hard numbers on this data.....

My bad guys, I was typing too fast. I meant this air diverter seemed heavier than the whole hood itself. The diverter that seals the intercooler with the hood, black metal thing.

As for the hood scoop screen, yeah its light, but you will obviously get some restriction, don't you think?

You miss quoted me LyveWRX :). The heavy part I was talking about was the diverter, NOT the screen.

Sorry.....

Sorry bout that,

Yeah any time you put interference in a flowing passage you will cause some restriction. If any one can figure out the total
X-sectional area of the scoop and the total real area of the 1/4" diamond mesh figuring the % of the restriction shouldn't be too hard...

I don't think the percentage of restriction is relevant- mostly it's does the intercooler still do what it's supposed to or not? In this case it does, so keep the screen and keep the intercooler free of dents- that's what I'm gonna do anyway...

Somebody posted something about (forgive me) a fin comb to straighten out the intercooler dents etc. Anybody know anything about that?

I got a couple of bent fins while taking it on and off for the uppipe install. I figured I'd use a flathead screwdriver to "fix" them. After making another 1 or 2 fins worse, I decided I'd let them be. That is some SOFT aluminum!
