I am trying to figure out the difference between a few choices available for upgrading the air filter in my 04 ESV and I am hoping that someone can shed some light on the differences between these three options and make recommendation as to which way to go?

The first option is of course to replace the factory filter with a K&N filter. Part Number: 33-2135

The second option is the 77 kit, part number 77-3023KG

The third option is the FIPK, part number 57-3023-1

Did you ever get a response to your question?
I have a regular Escalade 04 that I am using to tow our Airstream and would like to improve mpg and hp.

just get the cone from K&N it will raise horsepower and MPG, while the kit will drop horsepower and raise torqe because the stock ductwork is great, if you're worried about MPG get a supercoil and a set of electric fans, if yours didn't come with them
