I have an 03 G35 coupe automatic and am looking for some simple upgrades for power and sound... I'm mildly retarded when it comes to mechanics and have no clue what to look for. I have a K&N intake/ filter and want to do some more mods without breaking my bank... any help would be appreciated. Thanks!

 

if you want some "COOL" sounds get an intake. intakes rarely give you any hp gains its just for sound. combine the intake with a MD spacer it will sound pretty sick and with the spacer you should feel a noticeable difference.

 

Here, let me get that for you..

What are some basic performance and sound upgrades for my g35?

 

How difficult is installing the spacer, and would I need anything else to go hand-in-hand with it?

 

Add a Z tube to the mix and you're good to go.

Spacer install is easy and straightforward if you know your way around basic tools. There are good DIYs here and on infinitihelp.com and the Motordyne spacers come with very detailed instructions as well.
