2x Upstream & Downstream O2 Oxygen Sensors For Mitsubishi Lancer 2002-2007 2.0L (4-Wire)

Got a 2002-2007 Mitsubishi Lancer with the 2.0L engine?

If your check engine light is on or your gas mileage has tanked, these are likely the culprits.

This set comes with both the upstream (B1S1) and downstream (B1S2) oxygen sensors, so you can replace them all at once.

They're a direct fit, which means no messing around with wiring—just plug them in with the blade terminals.

They're built to last with a zirconia element and a stainless steel sleeve, plus they've got this double sealing technology with gaskets and rubber plugs to keep everything tight.

These are for the naturally aspirated engine only, not the turbo model.

The wiring harness is about 372mm for the upstream and 509mm for the downstream.

They come with a 1-year warranty, so you're covered.

Easy install, better performance, and hopefully that engine light will finally shut up.
