Purchased a stage 1 pro-dry aFe intake from an E46F member who said it was for the 325/330. Went to install it today but my stock MAF o-ring is too big to fit into the billet adapter. It is supposed to go inside the billet adapter, right? That's what it says/shows on the installation instructions. Could this be the 323/328 intake instead of the 325/330? Second pic shows how big o-ring is in relation to the adapter. I am having so much bad car luck these past couple of weeks... :thumbsdown
