Something else you can do is take a couple of washers and hinge up the back of the hood and remove the rubber seal... this will allow more hot air to escape the engine bay.

I removed the rubber seal on the back of the hood. Seemed to make a improvement on the underhood temps. Working on the ducting might be your best bet.

Your intake temperatures are getting high not because of the intercooler, but because of the engine bay temperatures.

In order to lower your IAT, you should consider ceramic coating your hotside, manifold, o2 housing, and maybe even the downpipe. After that, stick a turbo blanket over it and wrap the pipes up good. I doubt you'll have temp problems again. Additionally you can have your piping and core 'performance' coated, which will help keep heat out. Also take a look at your intercooler, fan, and radiator setup. If there is nowhere for the fans to draw air, it's going to trap it all under the hood. Maybe get some more efficient slimline fans?

I recommend TCC in San Antonio.

OEM fans outflow all slim fans. Been tested many times. A shroud will make a huge difference as others have said. These cars don't have "O2 housings" like DSMs. I agree with turbo blanket.

Then you should still ceramic coat the entire hot side, downpipe, and manifold.

It also helps to NOT run unrealistic not needed long tube turbo headers

Your cooler needs to get air to work properly , if you want it the best MAKE the air go through the cooler , Air will always take the path of lease residence

You need a piece of alum droping down about 1 inch then out about 3 inches like a scoop picking up air from under the bumper then you need 2-3 inches all around the IC to hold the air and make it go through the IC

The turbo header isnt a hugh issue the raid causes more under hood temps then anything at about 200 deg x the size of the raid so any place you can rought the piping away from the raid and I would wrap the piping in the engine bay then see with the scan tool is and by how much they drop
