i just bought on ebay a pro flow adapter kit on ebay for 99 cents. it doesnt have the filter but it says it can only use the uni replacements. do i have to buy the special replacement filters or can i just buy a uni pod filter that fits the dimensions. also can i put a K and N filter on a uni plate. i dont think it should matter as long as the clamp on peice fits good and tight. thanks

 

Measure the adapter and look on K&Ns site for one that will fit.
