When installing the AEM intake and connecting the stock MAF sensor with the AEM MAF adapter, which way to you start to thread the bolts through, going through the AEM adapter first into the stock MAF sensor or the other way around? When I was trying to install it the other day my stock MAF sensor does not have threads on it to feed the bolt into, hence the two pieces would just fall off. Are there supposed to be treads on the stock part?
