THINGS TO KNOW ABOUT THIS ITEM:
Reman units are notorious for being bad, even right out of the (new) box.
For performance applications, as well as to get a stable MAF unit since OEM reman versions are very unreliable, many turbo regals have been switched over to LS or Corvette style (3″ or 3.5″) MAF sensors. Most Buick vendors sell these aftermarket / conversion type sensors. And these non-factory units DO require a MAF translator box to use.
OTHER NOTES:
The newer stand-alone style ECU/ECM units totally eliminate the stock maf sensors by utilizing a speed density type of system within them.
