EO lookup
An EO identifier is a starting point for document research. Showgone does not confirm vehicle coverage from a number alone. Open the official source and compare the exact product and application details.
Open the official CARB aftermarket parts database
The official database opens in a new tab. Showgone does not fetch it or automatically assess its documents.
What to compare in the source document
- Identify the manufacturer and exact part number on the installed product or its label.
- Locate the official EO document and note its revision and date.
- Read the listed vehicle years, model, engine, calibration and installation conditions; record any exclusions or missing details.
- Keep the source link with your parts record. Ask the manufacturer or an appropriate inspection professional about unresolved application questions.
Keep an EO identifier in view
Enter a number to open a research reference page. It starts as unresearched; this does not search or retrieve an EO document.
