Found this kind of filter on ebay for 6 bucks apiece, just wondering if it might fit our motors??? Says it will fit the ISB, thats what these are just dont know if they are exactly the same..

No they won't. The thread size on that filter is 1 1/8" - 16, where we use 1-16.It does fit many ISB's and QSB's, but not the Dodge ISB.
