Can anyone tell me where to find clear corners for an 05 coupe and how to install them

http://infinitipa.zoovy.com/category/cosmeticupgrades. That's one of the sites where you can get them. They are very easy to install. All you have to do is pop/snap out the amber corners from the wheel well and pull out.

You can try Grubbs Infiniti and Performance Nissan for around $30-$33 plus shipping. Do a search for clear corners in the DIY section.
