Just started getting 170 / 173 codes and CEL.

When it rains it pours I suppose.

Anyone point me to the best price from a reputable company for a new MAF insert?

I've read about $90 inserts and wanna try that first.

The "inserts" are either made in CHINA or for other cars!

Stick with an OE Bosch unit
