It definitely makes a difference. There's a velocity stack inside the V&H intake. But without a tuner, like the FP3 to increase fueling, your performance jsut won't improve. The engine runs too lean to begin with, increase the air and it just gets leaner. Too lean to make more power. The FP3 recalibrates the ECM to match the increase in air flow.
