Easy to uninstall your old sensor and easy to install the new one. Just plug it in and screw it in. Came shipped very nicely and fast and no more emmisions control light! If your engine is running rich this fixes that problem.

Great price and OEM fit and quality. Chose this over the bosch part that some users have reported issues with.

Was exactly what I expected it to be and no more cel light. I had no problems passing my emissions either :-)
