maf question

[pgboxters]

I bought a bosch maf part ending in .124 to replace my old one The factory seal on the box was open incidently, Then I read that genuine porsche mafs are better tested than the same part from bosch on this uk boxster site. The performance does seem alittle different and it sounded like it was sucking more air when I put it in then i disconnected the battery for 20 sec to clear it. Now im thinking I should get a porsche maf I know my old maf was bad and I dont get any cel or idle problems.

Bosch makes the PORSCHE MAF sensor, so I do not know that there would be any difference. You may just be more hyper observant of the sounds etc.. Hard for the

human ears etc., to detect any minuscule difference there would be anyway. You would need to connect an OBD device to see if you had different voltage, mixture, etc. readings. Sounds like you are OK. If you had issues, you would get a CEL, or will soon.

I guess I was so used to the broken one since I bought the car. Maybe the Durametric software would be good all I have is a code reader.

You don't say what year or mileage, that info is always helpful.

You don't say that the part you took out and replaced was the .124 part, same as this one. Since it was opened, was the part itself labeled .124 also and not just the opened box.

Many MAFs sold on the net are the old one someone took out in the new box they just got the new one in. Buyer beware, know your source, something too good to be true usually is, etc. Since MAF's don't usually show a failure externally .... I'd ask the seller to replace the part with one in its original sealed package.

The "Porsche part is better tested" may well be a marketing myth.

I have 47k miles on my 00 s early model. I think the maf makes it sound agressive like a ricer, noisey I dont think its that good honestly compared to before. The part numbers are the same.
