Does a larger filter dissipate enough additional heat to substitute for an
oil cooler? Seems like asking a lot. Yes, a larger filter may offer more
filter media, but not necessarily. I seem to remember reading a
dissertation on oil filters some time back, and the amount of media varied
much more significantly than the size of the can would indicate. More oil
capacity in a larger filter I'll buy. My point was that for street
applications a quality filter that fits, along with the proper oil, is the
most important part. An oil cooler is a good addition when you can afford
it. And yes, this is all just my opinion.
Soap box is now stowed.
