The standard MAF housing size is 3 inches. When upgrading even a stock turbo vehicle with bolt on parts you can quickly reach the limit of the stock size MAF sensor housing, The sensor has a 5 volt operation limit. Once you either come near or exceed this limit the ecu can no longer calculate or torque and can cause the system to go lean. This can damage your engine and cause catastrophic failure.
Here at FK8TD.com we have tested the Rampage 3.5″ housing and have exceeded 520whp without hitting the 5 volt limit. Horsepower higher than this can be achieved depending on your vehicles set up. Rampage Fabrication has always delivered the highest level of quality and the best product possible.
