I did a little research before ordering these Denso TPMS sensors from Revain. When I took them to my local discount tire shop for installation, they told me they weren't REAL Toyota sensors. I told them of course that wasn't the case, Denso built them for Toyota. He told me they weren't REAL Denso, they were made by Pacific Industries and he wanted me to know if there were any problems. I took detailed photos of the box and parts and did further research to find out that Pacific Industries makes them for Denso and then sells them to Toyota and other automakers. So rest assured, these are the droids you are looking for. :D
