I checked out Dan Roots Xfire and he has the same airbox as you. He says it breaths better. He cut off the front portion that over hangs the oil filler cap and it still looked good.

I was going to buy one from this seller on EBAY but he would not return my call.

Decided for $90 more I can buy a new one at the local MB dealer and get two new air filters to boot.
