I want to run the larger MAF housing. The 2004 550 Anniversary Special Edition Boxster came from the factory with the 987 air box and larger MAF housing. So the ecu is programed to calculate the air volume with the larger MAF housing.
I figure this would be a cheaper way, then buying a custom flash.
