Unfortunately he doesn't list part numbers...
As per previous in this thread from Brian....you need...
Part # 113 090 01 29 - Y-Pipe with hoses
Part # 113 090 06 01 – Right side airbox with filter
Part # 113 094 16 82 – Right side intake tube (to radiator support)
Part # 113 090 05 01 – Left side airbox with filter
Part # 113 094 17 82 – Left side intake tube (to radiator supprt)

But it does mention SL55...so you "should" be right
b22b

the other thing I picked up on with this is that one of the throttle body clips (top) is missing....
