The case for genuine GM
- Ships from Dallas. Oxygen Sensors ordered by 3pm Central go out the same business day.
- Straightforward returns. No restocking games on oxygen sensors that did not fit.
- GM stands behind it. The oxygen sensors warranty comes from the manufacturer, not from us.
Getting the right part
When a component is superseded, GM documents why. That history is worth having when something failed early. Two vehicles off the same line in the same week can take different parts. The VIN is how we tell. Most orders leave the same day. Oversized and freight items take an extra day to crate.
