i got a dodge neon r/t 2002 is it worth buying the INDY Intake Manifold?

 

Since you have the RT and it doesn't have that stupid plastic intake manifold, you're intake manifold should be good. The Indy flows a bit better than the intake manifold on the RT but it's also expensive for only a slightly larger gain. If u want a better flowing intake manifold than what you already have, you should just port yours.
I would say that it would be worth the extra money if u has the plastic intake manifold that comes with the regular neons though.
