Review on UPSTREAM Oxygen 8946741010 Highlander Madlife by Thomas Johnson

Automotive enthusiasts, you won't be disappointed with this product! Based on my observations, the UPSTREAM Oxygen switches and relays installed in my highlander have enhanced my car's overall performance .The installation was simple and the product has sturdy construction. The pros? The switch is easy to locate and operate, and the relay smoothly manages high currents. The only con is the price which is a little on the high-end, but worth it for the increased performance..
