I currently have a 24x12x3 fmic on my car. At what point (on my pump gas set up) do I need to switch to something larger? The one I want is another cheapy on ebay, but I've seen it work really well on high hp applications and is 31x12x4 but I don't know if that big is necessary yet or what it will take to make it fit. Let me know what you all think. Thanks
