Review on 🚀 Enhance Engine Efficiency with Denso 234-9122 Oxygen Sensor (Air and Fuel Ratio Sensor) by Alejandro Silem

Delivered on time. 1/2 the price of Bosch or NKG. Supplied with copper based anti-seize lubricant in a tube. As long as you have relatively easy access (which this product doesn't reflect), you can easily replace the old one with the new one. If not, consider purchasing a specialty key, such as a B. Cal-Van Tools 843 Oxygen Sensor Wrench or similar wrench that allows you to attach a breaker. You need to reset the check engine light. To do this, buy one of the portable electronic diagnostic tools. My wife's car has 5 sensors so I paid for everything.
