Yours is a 2000 which is a split year. If it's an early 2000 it will have two. If it's a late 2000 it will have 4.
Do you have two pre-cats in the down pipes or not? If you do then you have 4. If not, then you have 2.
If you only have two, the correct part numbers are as follows (taken directly from the NGK website):
NGK #23151 - Bank 1, Sensor 1 (Upstream)
NGK #23099 - Bank 1, Sensor 2 (Downstream)
If you have four, then these are the correct part numbers:
NGK #23122 - Bank 1, Sensor 1 (Upstream)
NGK #23506 - Bank 2, Sensor 1 (Upstream)
NGK #23099 - Bank 1, Sensor 2 (Downstream)
NGK #23099 - Bank 2, Sensor 2 (Downstream)

I just got off ngk website,,,it doesn't show 23151 anywhere for my year.... it says 23122 for b1 s1 non cali ...federal emission
Oops, I meant to pull the part numbers for a 2000, the ones above were for a 99.
The part numbers should be:
NGK #23122 - Bank 1, Sensor 1 (Upstream)
NGK #23506 - Bank 2, Sensor 1 (Upstream)
NGK #23099 - Bank 1, Sensor 2 (Downstream)
NGK #23099 - Bank 2, Sensor 2 (Downstream)
Take a photo of the downpipe. Are there two pre-cats or one?
Until you answer that, no one can help you. I don't mean to be rude, but that's going to tell us if you have 4 O2 sensors or 2.
