First let me say that ordering from 1A was a breeze! The part came and it was exactly what I ordered. I received it in a timely fashion. It was hundreds less than my local store! A difference of more than 400 dollars. Would I order from 1A again? Absolutely! Would I recommend anyone order from 1A? Absolutely! My car is operating beautifully!

Problem solved
You guys are freakin awesome!! Installed the air flow sensor as soon as I got it. My car isn't mad at me anymore(fingers crossed). The sensor is working like a champ!! This is the second time I have ordered from you guys and I was not disappointed. Talked to a wonderful lady at customer service. She was polite and made sure I was taken care of. Can't remember who it was though. If you can find out who the nice lady was tell her i said thanks, and give her a raise!!! You guys rock! Really appreciate everything. Keep up the good work. Sincerely, Andrew Digilormo
