<div style="color:black;font: 10pt Arial, Helvetica, sans-serif;">Curious Q. I have wondered the same thing. However, if you look at filters for modern cars size dos not seem to matter. Many engines today call for a 3 in long filter not 4 to 5 inch.<br>

<div id="yiv3587799047">
<div>Someone please explain to me why the filter required for my 1.8 ltr MGB engine (51515) is so much larger than the filter called for the spin on conversion for my BN2. (51516) Just to add to the confusion, a cross-reference chart for either filter calls out the other filter as an alternative. Does filter volume make any difference from either car?
