Did you know that they were only available on Duster Twisters? Low performance 318 and /6 engines only. There was no connection to the carbs or air cleaner, just a small hole underneath each scoop. So, yes, they were fresh air, sort of, but I'm sure they made no difference at all in performance.



should be good for AT LEAST 60+ horse on a standard /6!
