Before you buy for a Ford Flex
- Match the engine. The EOs here list 3.5L Ecoboost. A part listed for one engine is not covered on another.
- Match the model year. Use the year filter above. EOs are often extended with new years later; a newer EO from the same brand may cover your year.
- Read the remarks. Some rows exclude certain test groups or require keeping the factory air box or hydrocarbon trap.
- Keep the EO label. The maker supplies a label with the EO number ("CARB D-xxx") to put under the hood for Smog Check. How to read it.
An EO exemption only says the part was found not to increase emissions on these vehicles. It says nothing about power gains, fit or warranty. What an EO does not mean.
Questions
Is there a CARB legal air intake for the Ford Flex?
Yes, at least in the EOs we read: 1 listing from K&N Engineering name the Ford Flex for model years 2014–2019 (EO D-269-94). Each EO covers only the exact years, engines and part numbers in its table, so match all three to your car and keep the EO label on the part.
How do I prove a part on my Flex is smog legal?
Keep the EO label from the part maker in the engine bay and a copy of the EO. At a Smog Check, the inspector compares the part with the EO number. If a station questions it, BAR's Smog Check Referee can inspect modified vehicles. See our guides on the EO sticker and the Referee.
