The bungs are there for anti-lag systems... If you do not run anti-lag which no cars in the US do unless its aftermarket, you just plug the bungs up with a bolt that threads into them... Thinking about it, you may even be able to get an egt probe into one of those bungs... I dk if it'd be the optimal place for one, but it may work...

The 2 bung are also called "secondary air intake". In WRC they utilize them as
Anti-Lag system or Missfiring system, it's standard on all Japanese EVO,
not on US EVO. You have to plug them if you are using in USDM EVO
this is a quality piece, the design is almost identical to HKS manifold for fraction of the cost.
Also this is also identical to GT SPEC manifold as well.
