To start, why are you replacing the MAF? Is there an indication from the vehicle or an independent source that it needs to be replaced? The reason I ask is because it's unlikely you'll "see dirt" on the MAF primary element. Usually, a Check Engine Light is an indication but not a definite clue. You'll have to have the code(s) for the CEL extracted to tell if the problem is truly a faulty MAF. You don't want to replace it just like an air filter. So what's the problem?
