Are there any differences between the 03/04 auto/manual engines and the 05 auto engine besides the more aggressive ECU?

 

No one knows? I read that the plenum might be different on the 05's any truth to that? Also what about the cooling and structual improvements to the engine in the Infiniti press release for the 05's is that just for the 6 speeds?

 

From what I recall, it sounded like just the 298HP engines... as if that makes sense. But that's what it sounded like...
