O2 sensor replacement options

NGK and Denso are both reliable options for O2 sensors. Many people prefer Denso for Toyota and Honda, while NGK works great for most vehicles too. Just make sure it’s the correct part number for your car.

I have a hemi 5.7 swap in mine and it's throwing a bank 2 downstream code. Which one is correct or best?

56029050AA or 56029049AA Both say for downstream use, not sure which way to go. One is $55 and the other is $75. My luck and history says it's the $75 version.
