I've changed 5 times the freaking MAF. Its seems the air filter blows it. Is any REAL SOLUTION for it??? is there any aftermarket one and also better??
A guy told me about a MAP that replaces the MAF, but haven't find anythig on internet. Please help me cause each one costs for me about US150.
Any DIY for this???????
I know that a Microtec or a Link would get me off this problem, but i dont want any of those ones.
OHH by the way it's a MY00 WRX
thanks.

 

Use something from Apexi oil-less filters. hard to tell unless you give a brief history about what you have setup... cheers.

 

Okay, lot's to deal with here!

Are you using an airfilter or an induction kit?
If it's a panel filter, is it oilless?
Can you confirm NO moisture is getting into the MAF?

Vibrations DESTROY MAFs.
Is anything resting against the MAF? Any pipework? Is the wiring nice and slack?
If you are using an induction kit, you MUST support the MAF, not just leave it on the end of the pipework. This means there should be some kind of metal arm that bolts to the MAF and to the bodywork, NOT the engine.

Air Turbulence
The air going into the MAF needs to be moving in a uniform direction. If you are using an induction kit, it would be wise to try using a length of samco (6 inches at least...10 for preference) between the filter and the MAF to let the air stabilise before it hits the sensor.
If you can mount the cone in the wing, so much the better.

If your car is one of the later classics (facelift) you will have a lovely fragile hot-film MAF. These really work best woth the factory airbox, and not much else.
