My Coupe Newbie Questions

2003 G35 Coupe 5AT.

I want to know what should I get before going in for a tune?

I just installed new spark plugs and an AEM 21-548R cold air intake.

what other bolt-on is recommended?

already have a plenum spacer coming in as well already.but don't know what else to get I am getting the car tune within a months time. just trying to get all the parts in and installed before doing so.

A new exhaust system. You have about all you can mod without rebuilding with aftermarket parts.

do I have lsd/vlsd?

Okay so I searched everywhere and none I've seen had a positive answer so I am testing my luck here.

I have a 2003 G35 Coupe. 5AT with leather/nav/rear spoiler/18inch rims.
Also how do I find out if I bought the sport package g35? instead of someone else who decided to throw the 18s and rear spoiler on.

Is there a way I can tell if its had lsd?

A lot of forums said look at the suspension red shocks black springs. But what if last owner replaced em? I havent checked yet.

Read the "Sticky" knowledge is power!

Since he has an '03 AT it's unlikely he has Brembo brakes! Would he know the difference?
At the top of this couple page there's a sticky with all the answers about which mods to make first. I suggest you read all the sticky and use our Search when you have questions rather than making threads!

Good Point... I guess if the previous owner swapped the Shocks, you will never know... Call a dealer and have them run the VIN and see what packages you are supposed to have!

There is a VIN decoder in the TOOL tab here on G35driver, just type it in and all that info pops up.

the vin decoder in the tool tab showed me wrong specs. I emailed infiniti they called me and verified that I have the Performance package w/ lsd. so it was great news.
