I got mine from
www.SummitRacing.com It is a 9" "K&N Extreme Filter". It came with a 3" high filter element which I changed for a 1" (?) high element so it would not touch my rear glass. I think the #KNN-E-3527 is the 1" high element. It was $33.69 and the rest of the metal housings were about $130.00 which I don't have the # for. Air is sucked in through the sides and down through the top. Can't get much better than that. Someone else mentioned that they had an 11" one in their CAV, but I like to see more out of my rear view mirror so I chose the 9". Hope I have helped. By the way, my CAV has a 302 & a Getrag 016 which may make a difference if yours is different. Joseph
