Herko Oxygen Sensor For Nissan Sentra, Altima, Frontier, Xterra (2002-2012)

If your Nissan is throwing a check engine light or running a bit rough, it might be time for an O2 sensor.

This Herko unit (part #HK41306) fits a ton of models from 2002 to 2012, including the Sentra, Altima, Frontier, and Xterra.

It crosses over with a bunch of OEM numbers like 226A08J010 and others, so it's a solid, reliable replacement without the dealership price tag.

It's brand new, comes with a warranty, and should wake up your engine's performance and fuel economy.

Herko is a known brand in the game, so you're not getting some no-name gamble.
