Not sure if they developed the hot film type, and I don't have a car running that type.
So I have done no research on that type MAF other then how they work.
As a rule of thumb when it comes to sensors I try to find out who developed them.
I try to stay away from copy cat sensors.
But in the end do your testing to make sure your MAF is your problem.
The Porsche MAF is a Bosch even has the same parts numbers I hear.

Thanks for the thoughtful reply.
The car is an '03 S. I just installed a motor from an '04 S. Had an odd "flat spot", put the factory tune back in, same thing.
Unplugged the MAF, problem went away.
