I am currently in the intake market. Initially,I inclined to HKS foam-style filters,but I have found tons of this kind stuff as I did research on ebay. Very few are genuine HKS,but they seems that all are made of the same material. I even found dual-filter one for G35. I am wondering if anyone had experience with these products.

HKS offers 4-inch and 8-inch foam-style filters for 3 inch pipe. Dose 8-inch one fit the place under the hood? thanks for sharing your experience.
