Dennis Kirk have one only UNI air filter in stock (https://www.denniskirk.com/uni/factory-air-filter-nu-2278.p30847.prd/30847.sku) at closeout price of $US7.24. Normally $US28.99
Don't bother looking if you are overseas (else I'd have bought it myself). Their shipping is extortionate.
I went ahead and bought it but the shipping is $7.99 USD to me. I will offer it to you but I doubt I could beat their deal.
Thanks for the offer Walt. They wanted to charge $US110 postage, More than a day's pay in total!!! I'm sure it could be done for cheaper but nevertheless it would cost more than I can pay.
That seems absurd. I will see if I can get a price.
