This product was a perfect replacement for the blower motor on my 2006 Infiniti G35 coupe. My a/c stop blowing cold so I replace the relay and that didn't solve the problem. I took it to the dealership and had it diagnosed and they confirmed it was the blower motor. The wanted to charge me around $450 to install, $250 being for the blower motor part. I priced the part at my local automotive parts store and they wanted $150. I decided to purchase this one and install it myself which took about an hour. Works like a charm but like others have mentioned its just a tad bit louder but not loud enough to bother me.
