Unfortuantely it might require some modification to fit. Many people have used Focus intakes to install on the Contour, But the problem with them is usualy the hole for the MAF... On a Contour intake the MAF just goes on after the piping, then the filter clamps to the MAF. On the focus the MAF just removes from the stock tubing and can be bolted into the CAI's Tubing. Do you have a picture of the tubing on this CAI?
