I know there is a few threads out there about this but I figure I post it anyway.

I just finish getting my car tuned by Chris at AMS (thanks Chris) the car was running strong and boosting hard. One day after I launched my car it started running crappy. My evo kept sputtering and dieing off. So naturally i changed my spark plugs. The car still ran crappy so I pulled the plugs and they were extremly black (abnormal rich condition) I also noticed durring idle my afr was 12 and the idle was also irraticle.

I started a boost leak test and when I took off my intake I heard a loose noise. I took of my filter and found.....







I was like

So naturally guys Im looking for a MAF thats in good condition.

 

wow!...that's a lot of suction!

 

That's what I said to her!

 

lol

 

yeah thats what she said. we had a guy down here in NC who did the same thing. i wanna say he was running the 35r...........guess its time for a JDM MAF now eh.......lol

 

I don't think air can do that alone... There must have been other factors.

 

Wow that is crazy

If you cant find a used one from someone here is a link for a new one. (free ground shipping). Hopfully someone has one you can ****** up though.

I was thinking about just getting another stock one and so one reccomended hypoxing the sides will help.

 

Small children... or squirrels perhaps?

 

what othe factor would cause this??? I have a 57 trim boosting 28-30 ibs

 

I don't know man but it doesn't happen very often.

 

Didn't realize new MAF were that expensive. What's the difference with the JDM?

 

I think he ment to say JDM MAP instead of MAF. Just two different ways to measure the amount of air going into the engine. The preferred method is obviously MAP.

 

I know that DSM MAS units have a little frame that retains the honeycombs and keeps them from tumbling or coming loose. Does the Evo MAS not use such a thing?

 

Yes I concur. Small children and squirrels indeed can affect MAF imploding. The can do the same to speakers cones too

Those squirrels are especially well known for this. Top tip: Always check your air box or induction piping for squirrels when replacing/ cleaning filters. The damage can be very nasty.
