A few weeks ago my 03 Boxster S would stall at start up and had a rough idle. The CEL came on and my scanner revealed a P0103 fault code which indicated a high current to the MAF sensor. After reading about the code, I decided to first remove the MAF and clean it with a spray cleaner for MAF sensors at my local automotive shop. This was a simple first step and something to do before you buy a new part. The rough idle was gone for a few min but after going around the block the CEL came back on with the same code. I shopped this part at a few of the bigger Porsche parts guys online (like Pelican and Suncoast) and found the Bosch part on Amazon to be about half price! During the swap I checked the part numbers and they were identical. The DIY job takes about an hour and all you need is a T20 torx security bit (hole in middle) and there are a bunch of videos on Youtube with step by step instructions. No reason to take the car to the shop for this fix if you have some basic mechanical skills.

Total junk. Worked for maybe an hour and then it started jumping from 9 to 35 rapidly. Idle, cruise, wot. Even with the key on and engine off. I should have known better for the price, but I got had. Listen to the bad reviews!

The part fits perfect in a Captiva 3.2 LTZ 2010.It is a little long, but nothing to worry about.Great price, specially if you compare it with some brands.By the way, is the same as the original one.
