Question MAF sensor placement/mounting

I have a couple questions about MAF sensors. Can anyone help?? I'm trying to use an intake on a 2002 WRX that does not have a mount for the MAF sensor. I've done a search and can't find any answers, so here goes!!

1. Has anybody, private or manufacturer, fabricated a MAF sensor mount for the 2002 Impreza that would allow you to use any intake (I'm imagining a short peice of piping with the sensor mount brazed/welded on)??

2. If I have to fabricate the part myself, what considerations should I make? (location, etc...)

3. Can I use MAF sensor from any other car?? Could I just wire it in?? What are the differences in sensors between manufacturers??

Any help would be greatly appreciated!!

Thanks,

/Chris

I know of no one that offers something like this.

If the intake you have is for our cars and it does not have a MAF sensor mount point, that chances are, it doesn't replace that part of the stock hose.

If you were to fabricate one on your own, I'd try using the stock one and molding it into a new piece of piping.

The placement of the MAF sensor is important - where it is and how far down into the intake it sits.

I would not recommend using a MAF sensor from any other car, chances are they wouldn't work anyways.

Thanks for the info. What about the sensor's placement allong the inlet pipe?? Can it be placed anywhere after the filter???

Thanks again,

dont expect stellar results ...
the ecu was tuned for where and what the MAF is in now.

Your ecu will be fighting it the whole way.

Talking I DID IT !!!!

I got my WRX and there were no performance parts being sold in the US. I took an old aftermarket intake from my Honda and cut it short enough to fit where the stock air box is. The problem I needed to solve was how to put the MAF into an intake pipe that didn't have a mount for it. The solution was to cut hole in the intake and file it so the MAF fit in very snug. Then you need to seal it. I used this stuff from Home Depot kind of like JB weld, it withstands high temps so it was perfect. All that said go buy a new intake that has the MAF hole already there!!! Sell the intake that you already have to someone with a car that doesn't use a MAF (like a honda civic). My intake worked fine but if I ever want to remove it I have to buy a new MAF since mine is permanently part of my intake!!! But I wanted to be first on my block to put in an intake. Hope this helped.......
