i want to fabricate an air grabber for a car but i don't want to do one that you have to flip a switch especially because i suck at electrical work but i want one that goes up whenever i step on the throttle because if you have to flip a switch and keep it up you might as well mold a hood scoop. does anyone know what to use? i heard something about using a vacuum servo and hooking it up to the intake manifold but i need a second opinion because i know the intake manifold carries fuel. i saw a setup on a ram srt-10 that had some stuff hooked up to the radiator and some other stuff i didn't see.
