This is the most significant finding (other than dyno results) that favors the GruppeM design:

The opening toward the bottom brake duct area means that if the driver's side bottom grille were opened, cold air would get to the K&N air filter. As for the throttle body, forget for a moment that it's a "Dinan." It's a stock BMW throttle body that has been bored out a little bigger with a bigger valve. Dinan's claims are a mere +5 hp max and +4 ft-lbs torque, and I am assuming this is at the wheel.
