You will lose a small amount of torque on the low end and see a very small gain up top. From most sites I have seen that make intakes for this motor, the gains on average were 3-5%. Either way its really just a piece that makes noise which is why the price of $300 to $350 isn't/wasn't justifiable for little to no gains when the intake first came out. The only real way to know if you are seeing gains is to dyno with and without the intake.....this is if you decide to not take the manufacturer's word regarding gains.
