You can visit http://www.knfilters.com and shoot them an email or call them. Go to the Vehicles needed section which is listed on the left hand side of the page. At the bottom of the page they have a form to fill out to submit your info. right on the page as well. They have the 2006 Honda Civic listed but it does not say a certain model it just says all. When I called them they told me they wanted the Hybrid as well. I hope this helps.
