Thinking to switch out my stock intake with Injen CAI but is it worth it to just upgrade the intake only with stock exhaust?

do you think I'll notice anything? Is it even gonna help the engine performance at all to upgrade the intake only?

Thanks

I/E upgrades are marginal at best. I would get a CBE after the intake and then a tune. That would be significant. But other than cool engine sounds I would not expect much out of a CAI.

I have the gem 3s and I really don't feel much. Maybe a bit in the higher end, it's IMO cool to have but not worth 500
