hi, i just bought a 2003 g35 sedan and im just wondering if a g35 coupe spacer plenum fit on to my sedan.thanks

 

Yes if it's a pre-2008 coupe.

What size spacer are you looking at?

 

motordyne 5/16

 

FYI parts between the 03-06 sedan are all pretty much interchangeable with little to no modification. You can also use alot of parts that are made for the coupe and 350z with the exception of exhaust (without alot of modification) and a few other parts.

Here is a good place to start looking for most questions you might have: https://g35driver.com/forums/g35-sedan-v35-2003-06/196616-look-here-before-starting-new-thread-2003-2006-sedan-faq-s.html
