Review on 🚀 Denso 234-4162 Oxygen Sensor: Ensuring Optimal Engine Performance by Bill Dooley

Downtime less than 4 months and less than 2500 miles. Only 30 day return window so I guess that's my loss. UPDATE: I spoke to Denso customer service and discovered that the product warranty does not cover my purchase as Revain is not an authorized Denso dealer meaning they do not know where Revain sources this product so they cannot guarantee that it really is their product. However, after speaking to Revain's customer service, they agreed that I would return the item and receive a full refund. So I give Revain 3 stars for customer service (not anymore because they still brand the product and link customers directly to Denso's website if they indicate they need help with a product, but Denso won't help .).
