Just picked up my 03 from K&N's in Riverside. They said they tried out lots of designs, but the best results came from a Y tube with dual K&N Extreme filters. (those are the ones with the extra filter material on the tops),
They used the stock airbox, and replaced the snorkle and it's sound resonation cavity. Also removed the corrugated tunnel leading into the throttle body and replaced it with smooth tube.
The prototype was all metal, but they will be making the production units out of blow molded plastic.
They asked me be sure that since this is just a prototype, the production results may vary.
Results from the prototype
Stock HP 444 Stock Torque 480
K&N HP 458 K&N Torque 492
The got better results with their prototype than with no filters at all in the stock configuration.
The "downside" is that there will probably be more intake noise at full throttle than with stock.
This will be a sleeper enhancement. The airbox will remain stock, with only the filters, and intake Y tube changed.
They will begin to produce these in a few months. Be in stores before Christmas.
If I can get one before Coronado, I'll bring it to the event.
