Ok the first thing i did like probly many others was the pop charger. then i found a thorttle body spacer not sure if that was worth it or not but would u take it off if i wanted to get a plenum spacer? and also after doing a couple things to suck in more air would u do a exhaust next to throw out some air

 

Here is a great place to start for a new 350Z driver: https://my350z.com/forum/engine-and-drivetrain/50429-new-350z-owners-read-this-before-doing-any-modifications-to-your-z.html

 

alright thanks man

 

Here's my final word on N/A mods for the non-revup 350z (i.e. 2003-05 non-anniversary edition).

5/16" plenum spacer
stock intake box from a 2006+ 350Z
high flow air filter such as K&N
Test pipes or high flow cats
2.25" true dual catback exhaust system of your choice
reflash or UTEC + tune

If you have the extra cash,

Headers before tune.


My advice for you is what is known on internet forums as LURK & LEARN. It means read a lot of threads and do research before starting new threads.
