Have you blown your MAF Sensor ?
If you have blown an MAF Sensor, please complete the poll. If you have not blown an MAF Sensor, do not participate.
YES, I have blown MAF Sensor with the following :
Totally Stock - No EVO Air Box

As I was saying before, I've blown MAF's when I did NOT have the EVO Airbox. In fact, I haven't yet blown one _with_ the EVO box, nor has anyone in NorCal that has one
There should be an addition to the poll "Bosch's worst part ever".

Stephen,This poll is only to develop a correlation between MAF failure and the EVO Air Box. I am sure there are folks who have not experienced failure both with and without the EVO Air Box. The only issue here IS MAF Sensor FAILURE and the EVO Air Box.

Stephen, I must admit that I love the car since it has been chipped and the EVO intake (by you). I was wondering, though, if altitude would present a problem? The biggest reason I added the EVO intake is the car already is starved for air, but I wonder if there could be something here in the thin air? Or it could just be a lousy MAF!
By the way...correlation has nothing to do with causation!

The commercial sensitivity not withstanding, sometimes we need to observe that an aftermarket part can cause TT owners grief.

Here is my response from another board.
If it is a problem why have I not blown mine? Why has my employee not blown his? Lets take a pole on the average miles driven in a week. I very seriously doubt that any more than a handful clock the mileage I do and I have not had a problem.
If the MAF has any issue at all the added air flow would create an issue. If the MAF is healthy then there are no issues. Just like the plug issue. The chip got blamed but the plugs if old or the wrong heat range fouled. It wasn't the chip rather the plugs. If the plugs were healthy, no issues.

I don't disagree with Sharkster that the MAF is a poor excuse for a part, however the correlation is significant as it can show that the efficency of the EVO Air Box simply cannot be handled by the existing sensor.

I'm guessing that's why Porsche started to outfit 04 and newer cars with the new style one. They must know something we don't yet

That being said...There does exist a theory the EVO box may cause more frequent MAF failures. Unfortunately us P car owners will never have enough data. I was led to believe EVO did testing. Perhaps this data is available (along with the sampling plan).

Yea and I have still had some dealers call me to say that our chip is causing a misfire issue. I have explained the TSB to have them say they did no know that. They change the plugs and call back with a "wow"

? Tell them it's those six lil' French buggers that they stuck in there. I remember way back in summer of 03 when my car was misfiring like a **** Kevin and I were on the floor (he was showing me how) checking the plugs out. They were not too happy lookin' at all.The moral is, if you have an 01 and even if you don't plan on chipping take the car to the dealer and print out the TSB for the FR5-FR6' and have them change 'em out. Your car will run so much better.
