Perfect fit for my Nissan Xterra. The batteries in the factory TPMS sensors died after 100,000 and the dealer replacement cost was ridiculous. Other aftermarket manufacturers offered a replacement, but it didn't fit exactly and didn't work. They worked on the first try and my TPMS light went out immediately. The installer used a scan tool to install them and the pressure readings were accurate. I've heard they can only last 5-6 years but the price difference is worth it.
