im just wondering because im about to buy an intake adapter and an aem dry flow filter, and the filter has two options, one with a whole for ait sensor or wone with out. i thinking about the one with thte hole so i could put that questionable tube in, it looks like a vacum line.

As long as you put it in the right location, between the filter and the MAF, you should be fine.

I'm looking at those filters as well -- where'd you find the intake adapter?

What size filter are you going with?

i found a 3 inch adapter on ebay but it wasnt the one i was looking for, it fits though. i bought one from autozone and it doesnt fit but it was a 3 inch and it had a little whole for that tube. aem has 5 in. long filters, im going to use one of those.
