Hey guys, I am looking for schooling on the operation of a 70-later Road Runner airgrabber scoop set-up. Not the air cleaner assembly but just the scoop part. How does it activate? any special parts?
any info would help. thanks Henry

If I remember vacuum held it shut and when you got on it the vac would drop and the door would open. I might be wrong it's been awhile.

Simple dash mounted vacuum switch to open or close the A/G door. An ignition activated electrical solenoid valve on the open circuit would bleed off the “open” vacuum side when ignition was off, and switch left in the open position, allowing a actuator mounted spring to close the door. The system runs off a vacuum reservoir and is not responsive to changes in manifold vacuum directly.

I don’t I’m afraid, pretty sure it was cable operated similar to the 69’ Plymouth “Fresh Air” system. The 71-72’ Dodge Ram Charger system was basically the same system as the 70-72’ Plymouth Air Grabber.
