O₂ sensor plug direction? pre cat or post cat?

The O₂ sensor plug is closer to the inlet featuring larger diameter.

Is it approved by California?

Sorry, no. It is prohibited from sale in California, Colorado, Maine, and New York due to State emissions regulations.

Welded or flanged?

Both ends adopt convenient flange design, so you can directly install the product using the preassembled 3 bolts on both ends. Require no complicated cutting or welding.

What to do if check engine light comes on?

Ensure that the gas and oil caps are on tight and that the oil dipstick is seated correctly. If the light remains on, it could be triggered by a faulty oxygen sensor, wrong installation of catalytic converter, bad spark plugs, malfunctioning thermostat or bad mass air flow sensor. If none of the above is true, please contact with the customer service ASAP.
