A friend has a 2005 4.6 GT with a Roush M90. We were considering a intercooler upgrade and I was wondering if anyone has ever installed a 11/12 GT500 intercooler? They are dual pass and were sold by Ford Racing as an upgrade for earlier model GT500's. I realize dual fan is always the best way to go but we are just looking for an upgrade, his car isn't raced. Any input or experience would be appreciated.
