The AFE looks very similiar to the EURO box I bought. The EURO box is more completely sealed. I did a flow test on the EURO box and with and without the snorkel and front elbows in place, it flowed the same, no difference. With and without the K+N filter (Cone shape on the EURO) it flowed the same so the K+N caused no restriction or minimal to even detect. With and without the lid it flowed the same. When I take off the stock air box I will flow it to compare. Interesting when I blew air into the snorkel to simulate 'ram air/scoops' the flow did increase. When I flow the stock box I will post all the numbers.
