Aftermarket EFI Air Filter

I have an aftermarket Billet Air Cleaner 8 1/2" Across x 3 1/2" High x 3" Deep on my LT 1 with EFI. Does any one know what a replacement element would be, or where to get it? The element is the size given above. I bought the unit a couple of years ago and now need to replace just the element. Thanks.....Larry

From your picture it appears to be a K&N style filter and all ya need to do is wash it with hot soapy water,hang it out to dry and then oil it with K&N filter oil........
