Hi

Ive been looking for a New MAF on flea-bay for some time.....

Will a MAF part number 986.606.125.01 fit my 1999 C4 cab ( ROW) - in previous posts I was advised to get 986.606.124.00......

thx

The numbers you are quoting there are 986 (Boxster) numbers. The latest numbers for the MAF on the 996 are:

MY1998-9 (non eGas): 996.606.123.00

MY1999-01 (eGas 3.4L): 996.606.124.00

MY2002 on (eGas 3.6L): 986.606.125.01

You need the 124.00

Edit: OOPS! - Todd and Loren are correct (see below) - Sorry about that - Not being careful enough!

Just to confirm something: the non e gas cars (my 98 Euro) use a different MAF than e gas cars? If I put a 2002 version in my car it wont work? I ask this because apparently the earlier versions of the MAF are prone to more frequent failures if a K&N or Evo intake is added.

Actually Richard the MAF for 2002- 996 cars is a 986 part number : 986 606 125 01.

996 606 125 00 is a knock sensor.

I guess that 3.4 and 3.6 MAFs are not compatible then.

Could someone please give me a definite answer regarding the possibility of a 3.4 car working with a 3.6 MAF? Apparently the 3.4s are prone to fail with the K&Ns, but not so the case with the 2002+ model cars.

You have been misinformed about the non-egas maf failing more than others. You can take your MAF and soak it in oil overnight, clean it up and it will be exactly as it was before the soaking. All maf's need cleaning periodically if they are exposed to oils, but the oil will not ruin them. If you are frying maf's, regardless of what filter you are using, you have a voltage (current) problem and nothing else.

Thank you all for your replies. For the record, I am not frying MAFs (knock on wood). I was just considering the purchase of a K&N Aircharger and those units have a "high coincidence rate" to make MAFs fail (apparently not due to overoiling, but the inability to handle the newfound large air volumes that pass through it).

If, after installing the new filter the current increases too much because of the increased airflow, put a low ohm resister inline to the MAF wire. This will reduce the current but not airflow. The stock DME sets the engine to run slightly rich at WOT, so this will lean it out very slightly, giving you additional power at the top end and less of a risk of putting to much current through the MAF.

I installed the K&N also, I did not use the K&N Filter.....I used an AEM Dryfilter (~$50). No oiling required with same or better performance than K&N. No MAF issues going on about 6 months.

part number that will fit is AEM 21-204DK AEM Dryflow - 3.50" Short Neck 5" Element. I used speedfreaks.com but you can search for other sources.

1999, could you please tell me EXACTLY what I need to add? This plus the AEM might just be the solution to my potential problem. I know I am not going to get any performance gains (minimal if any), what I am after is a "louder experience".
