Maf problems

1997 Boxster Tip.
NHP headers cold air intake,
accelerated in 1st gear to redline,
tip shifted to 2nd and engine stopped.
would not start
after towing car home it started when I wanted to back off tow truck. 2 hours
codes showed MAF short and tip load signal (Durametric)
replaced MAF
everything good
6 months 1500 miles later MAF failure.
replaced MAF, bought expensive Porsche MAF from dealer.
6 months later MAF failure.
I have rung out the wiring from MAF to DME no shorts and good continuity to correct pins.
Can a bad component fry the MAF?

Hello and welcome to the forum! Take a look at the link below to one of our site's DIY tech articles on the MAF - I hope that it helps you troubleshoot and hopefully resolve the issue.

Exactly why

What air filter are you using? What mods to the intake have you done? Ever cleaned the MAF? What does the intake nearer the throttle body look like inside?
