Hood Scoop Setup for Aftermarket TMIC

I just bought a CSS TMIC. It is obviously significantly bigger than the stock intercooler, so I was wondering what to do about the stock hood scoop vent and skirt. Should I just remove the rubber skirt, or do I need a different vent setup too? Will I need to buy something like this Zero Sports 'Cool Action' Hood Scoop Insert - Intake??? Thanks.

Look for an sti hood scoop splitter. It should be wider to cover more area. Otherwise, just look for aftermarket hood scoop splitters/plenums.

don't remove the stock rubber skirt unless you have something similar (that directs air) to replace it with

So I'd be better off leaving the skirt and only having air fed to half of my intercooler?

Better than removing it and having nothing yes, not better than getting something that will open up and spread air over the while IC.

Best bet is to find somebody local to fab one up for you out of aluminum. I know a guy by me does them for around $100.

You CAN run it without the splitter/skirt setup and have no issues what so ever. I have been doing for over a year with my TMIC. Thats how my car as dyno'd and everything. I havent had a tuner or shop guy tell me any different (they all said it was better than running the stock setup). But if you want to get the zerosports setup, that will work also.

So your hood scoop is gutted? No splitter or anything?

I'd say the one you linked would work as well though.

It may be easier on a pre 08 to run with the scoop gutted since the scoop itself makes a near 90 degree bend for the air to be re-directed through the intercooler. The 08+ on the other hand, the re-directing of air is almost 100% up to the splitter inside the scoop as there is no bend in the scoop itself.

So, yes you can get away with it like new said, but it still won't flow air to the intercooler as well as something like that last link you posted.

Been running my car without a splitter since I installed the turbo (over a year), havent had any issues at all. I will be getting the zeropsorts one to just add it to my "wow" list, but thats about it.

Awesome. Really good to know. A new splitter is just not what I want to spend my money on right now. Thanks.

If I remember right the CSS is identical to the TurboXS (which Im running), it will catch dang near everything that comes through that scoop. Like I said the splitter might help some, but IMHO its not a "must" have.

I'll probably get mine installed tomorrow so I'll let you know. But I'm sure Josh can answer that question now.
