I bought this MAF several years ago when I had my TTA. As I was diagnosing some issues I bought it from Advance Auto Parts, it is made by Micro-Tech Industries, part# 49-1022. However after some investigating it was something else. Ended up selling the car and this all I have left. It has never been used and is ready to install. Paid $75 for it, asking $60 OBO shipped within cont. US.If interested post up or give me a call 512-297-8842, ask for Jeff.
