Review on 🔧 Enhanced Denso 234-4738 Oxygen Sensor for Optimal Engine Performance by Christopher Ruth

Unlike the low flow sensor I bought which did absolutely nothing, this guy is perfect, cleared my upstream oxygen sensor code and let the ECM know , which my catalytic converters need a little attention to . Haven't bothered to create a new O2 sensor code like its useless cousin in the future. Make sure you have an oxygen sensor jack (a quick search here on Revain will help you find cheap ones), or have some creative swear words to teach the neighborhood kids. I knew this beforehand and didn't offend the neighborhood kids, do your civic duty.
