Great DIY. I've used this DIY to replace my headlights at least three times over the years. By far this is the easiest and fastest way to do it. Thanks OP.

 

I have a 03 sedan and need to change the headlights (due to fogging they look white). Is this process the same for the coupe and sedan?

 

I have a coupe and I changed my headlights ~10 years ago. Very pleased overall .I suggest you do it. These G35 stock headlights are notorious for getting white. You will notice the difference! They should be the same for Coupe and sedan. I paid ~$500 back in the day. Someone from this very forum
