Was prowling around my engine bay and I noticed a hole in the airbox. My guess is this is where the flow meter/filter minder used to reside. Ford does not show this separately from assembly. Are these glued in originally or do they sit in a grommet? Should I not even worry about it and just tape the damn hole shut?

 

A picture is worth a thousand words. I can't imagine your Ex would run well with a missing MAF meter.

 

I think he means the filter minder, but I didn't know the V10's had those. I thought it was a diesel thing only.

Yes the filter minder, I know I have seen them on gas motors on other Fords. Just though it was odd to have a hole ~ 3/4" in the side of the filter housing.

 

Well if its after the filter then your sucking in unfiltered air and I would plug it until you get it fixed.

 

Yeah, I know that. This is in the filter housing. I'm trying to find a picture of a stock V10 engine bay from the passenger side, but it seems most people that take pictures have swapped to warm air intakes already...

 

I just happen to have a stock filter housing handy down on the garage. Mine has 2 holes, can't say I ever noticed them before. Normal probably??

 

hmmm, didnt feel down to the second one, will check when I get home. Speed holes?

 

Yup... Two holes. Just like that, Wonder what the hell put them there for? Anti-icing of some sort using under hood air? Or just noise factor like they did on the Mustangs?

 

Mine has the same two holes, you can see the filter through them so what's getting sucked in is going through the filter and sensors before it enters the engine. I would definitely not plug those up.

 

It definitely lets crap in, just pulled the air box and looked inside, you can see where road spray has come up and been pushed over the years.

 

Water drains?

 

There has been threads on these before so do a search. My guess is that if the cold air intake got plugged by a foreign object on the road (newspaper etc) it would still draw air to run the engine, or possibly to equalize the pressure in the filter chamber, or a noise dampener for the chamber. Call Ford and ask.....but they probably don't know either unless they look in their archives for their engineers and do an investigation. Yes, it's a mystery and something an engineer dreamed up at one time and everybody said "fine with us, you're the engineer"..........let there be holes, and it was good.

 

Is that tiny little hole in the middle of the air box where the air gets sucked in? Why so small?

 

No, it's just an extra air inlet I case the main one sucks up a Walmart bag.
