I replaced the old sensor on my 1999 Buick LeSabre with this one, and it works like a charm. The acceleration feels much more responsive. My only complaint is that it was a bit more expensive than I had anticipated, but it seems worth it.

Installation was a headache
I had a tough time installing this mass air flow sensor in my 2005 Buick LeSabre. The instructions weren't very clear and it took longer than expected. Once it was finally in, the performance improved, but I wish the process had been easier.

Decent but packaging could be better
The mass air flow sensor itself works fine for my 2001 Buick LeSabre, but the packaging was a bit damaged upon arrival. Luckily, the sensor itself was unharmed. It took a little time to install, but once I got it in, the car runs much better now.
