I've never run one or seen one, but I'm guessing they can't be that bad. Just take a good look at the ports when you get it and clean them up if need be.
The Summit Stage 1 intake is either a Weiand Action Plus intake cast for Summit private label or an identical appearing copy cat.
The Summit Stage 2 is either a Weiand Stealth intake cast for Summit private label or an identical appearing copy cat.
The Summit Stage 3 is either an Edelbrock Performer RPM Air-Gap cast for private label or an identical appearing copy cat....OR its a Professional Products Crosswind intake cast for Summit private label which is an identical "appearing" Chinese-made copy cat of the Edelbrock Performer RPM Air-Gap. Wouldn't that be grand, a rip off of a rip off.
