Your high performance 'airflow' parts source for GM / Chevy 4.3, 5.0, and 5.7 Vortec Engines Everyone on every gm truck forum is praising this "mod" for horsepower, throttle response, less throttle at highway speeds? My guess is they're just happy to chirp the tires. I'd imagine GM put it there for a reason. Fuel efficiency? Distributing even air flow to all cylinders? I've been searching for the pros and cons but I'm only finding everyone praising it. I'm lost! Just wondering what you guys think. My guess is it would use more fuel with a bigger throttle body opening?
