Using the Denso brand gave me confidence because it’s reliable and designed to fit my LX450 perfectly, ensuring optimal performance and longevity.
In short, the upstream oxygen sensor is a small but vital part that directly impacts how well my 1997 LX450 performs, saves me money on fuel, and keeps emissions in check. It’s definitely not something I’d overlook when maintaining my truck.
