I was looking into information about the SAFC Neo and somehow worked my way to Intake Spacers. Found a company that makes them for 2002-2006 altimas so I fired off an email about them for the coupe. This is what I received:
We do not currently have any plans to make Intake Spacers for the new modelAltimas. We would definitely be interested in conducting some testing tosee if you would benefit from intake spacers.
Also, since your intake manifold is made of a plastic composite, it is noteffected by heat like the other Nissan engines are. So, heat soak isn't abig issue for you. You will not need a Thermal Intake Spacer to helpinsulate. But, we are currently designing an aluminum intake spacer for theVQ40DE Frontier engine. What this will do is shift the torque band lowerand provide a healthy low end and midrange power gain! Proper testing willneed to be conducted on the Altima to determine the optimal spacer design inorder not to hurt top end power substantially.
Please let me know if you have any more questions.

Not even sure why I posted this but I guess its an oppurtunity for someone to get something free.
