For a 06 WRV Alpine, the uptake for the air cleaner cannister is right behind the right rear wheels. I'm amazed at how quickly my whole engine compartment gets dirty with road grit, including on top / around the AC cannister. Opening the cannister would cause large amounts of grit to be sucked directly onto the filter media, increasing the dp across the media, and challenging the media with a potential grit "leak" directly into the engine.
The increase in dp across the filter media quickly defeats the purpose of increasing the delivery air flow (hopefully without an increase in airborne grit) to the engine; at $85 / filter, or $20K per engine, gain doesn't exceed potential loss, so the idea is a loser.
