I"m sticking with the SE (it's K&N?) until I find an element that's the same width or thinner withmore airflow capacity. I just don't like having my knee sticking out any further on the thick high-flow elements I've seen thus far. I did request a price quote from Zippers for the element and the round cover as it's used instead of the football. I spoke with a performance builder and he states the Zippers is more narrow than the Gerolomy Overflow air filter I've looked at, just a bit wider than the SE element.
