A really free flowing air cleaner also reduces the velocity of the air going through the carb thus reducing the venturi vacuum. That's why on a lot of threads guys bitc* that their new expensive free flowing air cleaner makes their car run worse.  See the Note at the bottom of the Secondary Throttle Opening Ranges in my post above. |
