If you are comfortable with the potential risks and are looking for a more affordable alternative to the OEM alternator, the TYC SX-3984 alternator may be a suitable choice. However, if you prioritize durability, reliability, and peace of mind, you may want to consider investing in the OEM alternator or a high-quality aftermarket alternator with a reputable warranty.
