[Healeys] K&N filters for a BJ7

[rpschauss at gmail.com (Peter Schauss)]

The K&N web site recommends part number 56-9237 which is a frustum with
dimensions 5 7/8 ->3 1/2 x2 11/16" thick.  A thread in the archives
suggested their custom filter # 56-9247 which requires drilling holes for
the mounting bolts and the air passages.

Any thoughts on the relative advantages or fitting issues?

Thanks,
