2-Pack Upstream & Downstream O2 Oxygen Sensors For 2001-2004 Pontiac Grand Am 3.4L

Got a check engine light on in your 2001-2004 Pontiac Grand Am with the 3.4L engine?

Chances are it could be an oxygen sensor acting up.

This bundle from Topcn-autoparts gives you both the upstream (front) and downstream (rear) O2 sensors in one package.

That's two sensors, a direct-fit replacement for the ones before and after the catalytic converter.

They're 4-wire, heated, narrow-band sensors that screw right in (thread size M18, 7/8\ hex).

All metal housing, blade terminals—just like the originals.

Swapping these out can improve your engine's performance and fuel economy.

It comes with a 1-year warranty, and it's a specific fit for your Grand Am, so no guessing games.

Time to get that light off and breathe easy!
