I ordered this and the upstream sensor a few weeks ago. Removing the old ones were a PAIN, but installing was extremely easy. They come with anti-sieze preinstalled on the threads. The price and quality is unbeatable. I highly recommend on buying these.

Well, what can I say it was easy to install but the engine light is still on. Although, every where I search and researched it said it takes about 20 cycles and driving it for a few miles.
Customer Q&A
Im installing long tube headers would these be the right ones?

headers make no difference as long as there are holes for your oxygen sensors in your exhaust before and after the catalytic converter. If that was your question?

I need to change both oxygen sensors. Is this one good for both?
