I am going to be installing twin HS4s on my Spit 1500, and I need to get some
new air filters for them. Does the SU HS4 have the same air intake flange
configuration as the HS2? Or is the HS4 its own special bird?
Whatever filters I install will have fit within the confines of the metal piping
that delivers fuel to the float chamber of the forward carb. My guess is
that a K&N would work fine, but I am leaning toward the round LONGFLO -- if it
fits (!)
Any suggestions for filter types and where to get them?
