Claim Text:
1. An air cleaner assembly having improved dynamic wall stiffness, comprising: an air filter element having at least two opposing sidewalls, said filter element including an air cleaner housing comprising: wherein said lockable engagement rigidly and detachably couples said opposing sidewalls of at least one of said first housing shell and said second housing shell, said lockable engagement coupling and locking said opposing sidewalls together to deflect in unison with the effect of substantially canceling pressure pulsations forces on said opposing sidewalls, and wherein said lockable engagement is a rigid coupling providing dynamic stiffening of said at least two opposing sidewalls through said at least one wall stiffening member, said dynamic stiffening reducing housing wall noise by stiffening of said at least two opposing side walls against pressure pulsations present in an air stream in said air cleaner housing.
