Is there a K & N air filter for the 350z ? If so should it be put on immediately or does it matter?











Touring/Black/Auto/Burnt orange/everything except airbabs,nav.

 

Does this also improve fuel economy apart from more power as some have told me?

I originally presume no such piece would be available since surely Nissan tried to max out the power and thus put in a similar flowing filter already as stock..
