Got a 2000-2004 Toyota Avalon with the 3.0L engine and dealing with a check engine light?

This set from Autodayplus includes both the upstream and downstream oxygen sensors—everything you need for a full replacement.

They're heated, direct-fit sensors with 4 wires each, and they screw right in.

Just get the old ones out and pop these in.

Comes with a 1-year warranty, so it's a solid fix.

Get your engine running efficiently again!
