What we read, and what we leave out
A row goes on a vehicle page only if its part number, model year, make and model all pass our checks. Doubtful rows stay out and the EO page points to the PDF. In our last spot check, 30 of 30 randomly sampled rows matched the original PDF exactly (2026-11-11). Every row links to CARB's original PDF.
Questions
What does "CARB legal" or "smog legal" mean?
In California, Vehicle Code Section 27156 prohibits modifying a vehicle's emission controls. A part maker can get a CARB Executive Order (EO) exempting a part after CARB finds it does not increase emissions on specific vehicles. "CARB legal" means the part has such an EO for your vehicle.
How do I use this site?
Type your make and model (for example "Mustang" or "F-150"), a part number from a product page (like 57-3108), or the EO number from a sticker (like D-269-110). The vehicle page lists every EO-listed part we found for that car, grouped by type, with the model years, engine, remarks and the EO PDF.
Does a listing here mean the part is legal on my car?
It means the part number and your vehicle appear in that CARB EO. Match the exact model year, engine and any remarks, and keep the EO label on the part. The final determination is made by CARB and the Smog Check station or Referee.
Why is my car or part missing?
CARB publishes EOs as separate PDFs with no complete list. We found 757 EO numbers by checking CARB's file names, read 690 of them so far, and copy vehicle tables only when every cell passes our checks. Older scanned EOs are linked as PDFs only.
Is this an official CARB site?
No. It is an independent reference built from CARB's public EO documents, not affiliated with CARB, BAR or any parts maker.
