I jsut bought the intake boot for my car and I have seen people ask for the part number with no response. It is as follows

46023AA110

This is the boot that goes between the resonator box and the turbo.
It took quite a bit to get it as they ordered the boot that goes from the turbo to the throttle body first, and then when I pointed out that the part was wrong and showed them which one I needed, they had it in stock.

Now after getting the boot on and hooking up some vacumn hoses correctly my mileage has taken a dump for some reason. I know I was getting unmetered air past the boot and now it is all metered, but this will turn out to be a severe drop. Any ideas?

I would think that your gas mileage would go up, because though you were getting unmetered air, you were also losing vaccum pressure and through that, your car normally has to work harder and uses more fuel. Are all of your hoses hooked up properly and tight?

Near as I can tell they are all hooked up right now. I used a diagram on this site and found 2 hoses that were wrong and got those sorted out. All appears to be in order. The only thing I can think of is the maf is now seeing more air through it and is adding more fuel.

Well i know that if you are sucking unmetered air into the system, then the ecu is not being able to recognize the gain and adjust fuel accordingly, therefore the loss in power. I would track down andy and all vaccum leaks to help cure this

I really don't have a loss of power, it is a loss of mileage. I did have unmetered air before I replaced the hose and now that all air is metered I have the loss of mileage. I may reset the computer and see what happens.

Well I disconnected the battery for a couple of days while I did the water pump and am assuming it was reset. My mileage is still really bad and am not sure why. No codes of course and the only thing I did was replace the intake hose. Maybe replacing the coolant temp sensor although the tech at the Subaru dealer said that the fans usually run all the time when the temp sensor acts up and mine work normally. Anybody have any ideas?
