In this day and age with diesel being so expensive it's imperative to squeeze as many miles per gallon possible. I decided to do a few modifications to increase my fuel efficiency and INOP it was totally worth it. These are the mods I have done to date....

1. Fitch Fuel Catalyst
2. Flex-a-Lite Syclone 14" fan w/ VSC speed controller
3. K&N air filter
4. Bosio nozzles installed and pop tested

I recently took a highway trip and yielded 36 MPG. The biggest difference was the installation of the Bosio nozzles, but the other mods have helped. My car runs great and in my opinion the money spent was well worth it.
