89-91 ZX2R Compatible Air filters AU

Used to be Unifilter.com.au, Uniflow is still Uni Filter?

I think the US unifilter.com company is main setup?

Ridiculous as it may seem I actually buy my filters from the USA simply because it is cheaper ($9.54US postage all the way from the USA)

I paid about $35AU (when the dollar was good) for my last UNI FILTER including postage from the USA

Yeah some things like filters are best not to buy genuine, The aftermarket ones usually perform better & are cheaper

Not sure what the US Uni Filter match would be? It says 87-07 EX 250 NINJA NU-2366 $15.95, Not sure if one of them would match up?
