2x Upstream+Downstream O2 Oxygen Sensors For Mazda 3 2010-2013 L4 2.0L – Direct Fit, 1-Year Warranty

This set includes both upstream and downstream oxygen sensors for your 2010 to 2013 Mazda 3 with the 2.0L engine.

Two sensors total—one's about 690mm long, the other 390mm—so you're covered front to back.

They're direct-fit, meaning no splicing or hacking wires; just plug 'em in and go.

Brand new from nafullparts, backed by a 1-year warranty.

They replace a bunch of OEM numbers like LFL7188G1A and LF8R188G1, plus cross-reference with 2344467 and 25025029.

If your check engine light's on or you're running rough, swapping these out might be the fix.

Easy install, solid performance, and peace of mind with the warranty.
