| Contact the Dealer you got it from and have them send you the right kit. Dry filter kit Item #: 75-5065D Cotton Filter Item #: 75-5065 In the interim put your stock intake back on you'll throw a code. Last edited by FC5452; 01-25-2013 at 07:56 PM. |

| A mass air flow sensor is used to find out the mass flow-rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure. Only thing I can think of why GM is Using two is that the mapping changed. seen this done in injected Gas engines. maybe Kory, Rob have a better explanation in the tuning aspect of it.
