I just received and installed the ROUSH cold air kit on my 2010 today. I will update after I get my car dynotuned. (shorty headers, magnaflow xpipe, macs boomtubes axle backs, and Roush CAI) I also put some ZMAX fuel and oil additives in today. Here are some pics after installation.
It feels and sounds much smoother and really screams at higher RPM's. I wanted an intake that fit well and would work with the stock ECU until I can get on the dyno. I knew ROUSH would be a no-brainer. The fit and finish are as good as the stock CAI on the 2010 GT500's. It is not loud like a Civic when you mash down on it, but I think that is because Ford already pipes the intake sound into the cabin with the sound tube thing. You can hear it suckin' air outside the car, but it sounds good with my exhaust setup.
Cool. I have been trying to find a shop that has a tuner and a CAI, but have yet to find any.
This is one my list as they claim you don't need tuning, just waiting for a local shop to give me a price.
I was thinking of getting the same CAI for my car, just BC I have a roush (stage1). The only thing is that... all you would be changing is the filter... you still use your factory intake tube. I think I will still use that CAI though BC it isn't a bad price either
