Review on 🚗 Enhance Performance with Denso 234-4048 Oxygen Sensor: A Reliable Automotive Solution by Fock Dean

This is the same part as the OEM sensor. You can buy a cheaper sensor, but it may or may not fix the error code. This one cost $50 considering the auto repair shop charged $350 for a replacement. It was a hassle removing the old one, you should definitely get a 7/8" O2 sensor head (separately) and I had to put a hose over the ratchet handle to break it. The new one was just too tight to install.
