Review on 🚗 HFP-WBS42 LSU4.2 Wideband Oxygen Sensor - Compatible with Bosch - Equivalent to PLX AEM 30-2001 4100 0258007206 - Replacement by James Edwards

Works great on my 427 SBC with 12:1 compression. Bringing Phytech to market means Street EFI. Even Fiteh was shocked that I could run this 02 sensor and it worked great on leaded fuel. They asked me to send them the part number so they can bring it and test it at home. It's much easier to find leaded racing gas at gas stations than ordering 50 gallon 104 octane drums. I had to hook up the sensor to my Bosch connector but it was easy as the wire colors matched perfectly. I didn't solder the wires. I've just used automotive heat shrink tubing connectors and they work great.
