Are the specs on the 2003 G35 coupe valve body different from the 2004 and 2005? I purchased the Level 10 valve body upgrade and the mechanic went to put in the new Level 10 valve body upgrade and found the valve body in my 2003 G35 coupe was different from the one sent to me by Level 10. Why would they different.

 

Yes I remember reading that somewhere, '03 is different. Its best to send your VB for upgrade. You can do a search at my350z forum.

 

Yea I know I found out the hard way I am now without a car for the weekend. I would think Level 10 would know these things especially after he ask me what year my G35 coupe was. Thank you for your response.
