Can 2013 parts fit on my 2011 g37 sedan?

 

Hey there, welcome to the forum.

I would implore to take the 20 minutes and place this same thread title in our search bar and follow other similar threads about this topic.
Key words like:

Compatibility
Year range
Trim years
2013
V36 differences

This will yield tons of info, most of this info will be old, most of this info will be in threads that have 5+ pages, most of this stuff will take more time than just asking such a broad question as one of their first ones.
There are many things that interchange being that they ALL share the same chassis code V36.
I would not be afraid of commenting on old threads (reviving a thread) as long as you contribute something to it. A thoughtful question, some advice, thorough observations can be examples. This usually notifies everyone that has commented on that thread, many times these are the folks you need their advice on and folks that could receive an email on a recent comment.
Asking certain question in 2024 with a different crowd in this forum might not get you the desired answer, this is why the recommendation for proper searching is given. The learning of the search engine will make increase the efficiency of how you yourself progress with the tinkering of your car. I joined a few years ago and many of the things I learned on my own about this car was at least mentioned 1-2 before, 7, 8, 10 years ago.

If you want to get your count up do so by commenting on others and/or older threads.

Engine is ALL the same
Interior design other than a few visual panels and color is the same
OEM wheels are not
Suspension only sport chages
Exterior is dependent on Trim

Good luck!
