datsun75 Posted August 2, 2017 Share Posted August 2, 2017 DO PEOPLE RUN COOLANT TRU THE COOLER PORT FOR MIKUNIS OR CAN RUN WITHOUT THEM JUST FINE? BENIFITS? Quote Link to comment Share on other sites More sharing options...
northwoodz Posted August 2, 2017 Share Posted August 2, 2017 Typically you run coolant through a passage to keep the throttle blades from icing up in cold weather. It hurts performance in the summer months by heating up the intake charge. Quote Link to comment Share on other sites More sharing options...
zbloke Posted August 2, 2017 Share Posted August 2, 2017 Even though they are called "cooling bodies" you don't actually run coolant as in engine coolant through them Your supposed to route your fuel return line through them but in practice I don't think I've ever seen anyone run with them hooked up My advice for what its worth:- Run without them hooked up to your fuel return line and if the car performs to an acceptable standard call it good and move on to something else Quote Link to comment Share on other sites More sharing options...
