Model # for Apexi filter N62 maf

[Sil#2]

Anyone know what the model # is of just the filter that can bolt on to the n62 maf?

I found these 2 but not sure which is correct:
Part Number 500-A021 = 3.35 inch diameter

Part Number 500-A022 = 2.95 inch diameter

I feel like both are pretty close to the 3" maf. Called Apexi-Usa and they send me the japanese instructions of the actual Z32 kit, BUT after finding someone to help me translate, there's no part # of just the filter.
