First off thanks for the compliments..In my case they fit, that is why I have used them. On the Valiant we originally had a K&N fancy Dominator filter on it. I decided to try the Uni I had and the car picked up almost a tenth and the K&N never went back on the car. The car went 9.11 with the K&N and 9.02 with the Uni. In fact the K&n is still sitting here in it's box.

Here is a picture of what I had on the Valiant before the Uni..
