Air filters?
 

I have a 74 260z with the original dual carbs.For the life of me I cannot find air filters for it except $50 K&Ns and I really don't want to spend $100 on air filters..I've looked everywhere and the only option I get is one big oval one..Any ideas would be helpful...Plus the previous ones were not the correct ones,they were squashed and manipulated to fit,not even functional.Thanks.
