I would strongly suggest researching about your current tuner to save your motor before she goes.
As for intakes, I have dyno tested the 2.5 intakes, 3 in intakes, and stock intakes with dorp in filter and Z1 maf tubes. They were all almost identical power wise (within 1%) Don't waste your money on intakes.
