GENERAL INFO: The Ultimate Porsche Mass Air Flow Sensor (MAF) Resource

[Nick_Richards]

Listen up 2000 Boxster owners... A lot of crazy stuff went down in 2000. Between the 1999 and 2000 Boxster model years Porsche moved from the 996 606 123 00 MAF to the 996 606 124 00 MAF as a part of their move to the drive-by-wire or e-accelerator system. Well, they had some issues - delays occured and even after they brought the new e-accelerator system to market they continued to have problems with the 124 MAF. The 124 MAF turned out to be highly susceptible to particulate matter. So, as good German engineers do, they fixed it post-haste. This gave rise to the 996 606 125 00 MAF but there's a twist. This required some changes to the engine control unit software. So what does this mean to you? A lot of confusion what MAF you need for your 2000 Boxster.

For the most part Porsche stopped using the 123 MAF after the 1999 model year. They then started their 2000 model year with the 124 MAF. Mid year they switched to the 125 MAF to address the weaknesses of the 124 MAF. If you are thinking, hey if my car uses the 124 MAF why don't I upgrade to the new 125 MAF? Well, remember that involved a change to the engine control software so unless you want to pay $1,500 to have your engine control unit software upgraded forget about it.

We've taken some pics, side-by-side, of the three mass airflow sensors.

Note that in one pic we have highlighted (in pink) three identifying marks that may help you determine which MAF your vehicle is equipped with.
