Jim wolf Pop charger replacement filter alternative

[ZenkiKid]

So I got a good deal on a g60 MAF for my ka24de swap that had a busted Pop charger with the carb number sticker attached to the MAF, I was wondering if there was a cheaper replacement filter that would fit the pop charger assembly, 50 bucks for a replacement filter for an add on to the oem intake isnt justifiable to me.
