I used their drop down menus to find out if this set up would work work my car. The drop down menus said yes. I got the parts and tried installing them and found that they wouldn't work with my car. I used extra parts to attempt to find a way to make them work and the car was running too lean and kept throwing codes. When i looked at the product info without using the drop down menus i could not find my car listed for the model year i own. There were changes between 2008 and 2009 and my guess is that these parts are made for 2009 on. Because the parts were briefly installed i can no longer return them. I'm out $300+(bought air box too) because i trusted their drop down menus to be accurate. Not happy.
