This was the right part for the right price. Man, after the rats chewed the wiring on my original sensor, my low-end rpm was really rough. Now my truck runs great - And Thank you 1A for the clear cross-references, etc., so I could make certain my order would fit.

Customer Service was outstanding and I received my O2 sensor within days.
