Autodayplus Upstream & Downstream O2 Oxygen Sensor Set For 01-06 Hyundai Elantra 2.0L ULEV

Check engine light on for an O2 sensor in your 2001-2006 Hyundai Elantra 2.0L ULEV?

Here's the fix.

This Autodayplus set includes both the upstream (before the cat) and downstream (after the cat) sensors, so you can replace them both at once.

They're a direct fit, with the right thread size (M18*1.5) and 4-wire connectors.

Just screw them in and plug them up.

They're heated for faster activation and come with a 1-year warranty.

Clear that code and get your fuel trims back in line!
