The application is vital to your CV. This is why it is the first page and not an addition. "Please find enclosed my CV" won't get you very far.
Your application demonstrates your writing style better than your CV.
The application puts flesh on the bare bones of the CV. It points out to the employer the information showing that you have the qualities the job calls for, and makes a statement about yourself and your suitability for the job. It should give the personal touch that your CV will intrinsically lack.
What do employers look for in an application?

- 19% Your value, not the basics, why we should hire you
- 18% Spelling & grammar
- 17% Personal vision & uniqueness
- 2% Brevity
