Good information! I knew that the MAF to throttle body hose needed to be different. Thanks EDC for the picture confirming that, and thanks to The Radium King for the part number. I must be looking in the wrong place, as I could not find a different number for that part.

Now a harder question concerning the 550 edition, that won't be so easy to verify. Did the factory modify the airbox to remove the resonance chamber, or did they modify the chassis (I kind of doubt that)? Also, for those who have fit the airbox, are the mounting points identical? That is, do you just bolt it in with the existing hardware, our do you need to modify or add things like bolts or washers?

Personally, I am not sold on the bigger throttle bodies until I see dyno data, not just "butt dyno" impressions. From experience, bigger throttle bodies need to be mapped properly to match the flow characteristics. Just bolting a larger one in and running it can lead to odd part throttle behavior. That probably wouldn't show up on the dyno, but would be felt in real world driving. I am not a fan of something that might give me 5 hp on the top end at the expense of drivability.
