GrimmSpeed put a lot of work into this intake. Using their FARO arm, they were able to map the engine bay in 3D to ensure a perfect fitment. They used that working envelope to maximize performance by eliminating the 90 degree bend just before the airbox. This contributes to decreased resistance, and helps with accurate MAF readings. The MAF sensor is located inside the airbox to ensure that the heat from the motor and headers doesn't skew its readings.
The GrimmSpeed cold air intake provides gains in horsepower and torque across the entire rev range. This includes gains of 3-4 ftlbs in the "torque dip," and peak gains of 6 horsepower as measured at the wheels on a Dyno Dynamics dynamometer. These gains are not achieved through MAF trickery either, as the air to fuel ratio remains nearly identical to the factory's. Additional gains (around 2whp) in the top end can be achieved by modifying your factory snorkel.
