Optimized Product Name: GM Genuine Parts - High-Performance Alternator (25888970) Review

When I tried this Automotive product, I was thoroughly impressed with how it brought power back to my car's engine. The installation was quick and easy, and the quality of the product was evident right from the start. The ACDelco alternator is definitely worth the investment, as it has improved my car's performance and reliability. My only con is that it's a bit pricey, but you get what you pay for in terms of quality. Overall, a great product for anyone looking to boost their car's power!

Installed in January 2017 and already out of service at the end of April 2017. The voltage was erratic the whole time he was in the car, but last week the output dropped below 11.5 volts. I checked the battery and alternator and the alternator was faulty.

I bought this alternator for my 2005 Corvette as it was described as an OEM part. The alternator ran fine at rpm, but couldn't hold the voltage at idle. It was so bad that I couldn't turn the air conditioning on while it was idling in hot weather. Kudos to Revain for the full refund but otherwise the product should not be listed as applicable to the C6 Corvette. This is also evidenced by Internet forums on corvettes.
