2005 Civic Ex - www.dry-cell.com

Looking for anyone who has performed this modification on a civic between 2001 - 2005, I believe there was a model change in 2006 and my car was the final year of the body make / engine type that it has. Pretty sure it has a wide band O2 sensor and I'm looking at purchasing a dry cell unit from:

http://www.dry-cell.com

I'm looking for information related to:

- Experiences from people who have used the dry cell and EFIE from dry-cell.com

- Experience using any form of HHO with a civic between 2001 - 2005 model

- Verification of the O2 sensor

- Curious if using the cell with the EFIE is all I need to do to get another 20-25% mileage out of my car

- If my car would require more than just tricking the O2 sensor, then what else have people had to do who own civics?

- Also anyone who have driven their HHO modified vehicles more than 100,000 miles, what kind of experiences have you had (long term effects on the engine)
