Ok so I am new to the g35 fam. I know you guys get this question a lot or get tired of it. Lol. Whats the difference if I buy autozone to oem? and can anyone give me suggestions on where to buy and look. Like a head gasket kit? thanks guys bare with me as I am learning. And can you guys let me know brands and stuff to look for that's oem or close to its standards

 

If it's a part that is a pain in the *** to replace or is critically important go oem.
So mostly everything.

 

Rockauto.com has an extensive parts list available for the G and offer a lot of OEM replacement parts.
