Review on Amrxuts 28103-AJ00A 4pcs Tire Pressure Sensors TPMS for Subaru 2008-2016 Forester Impreza Legacy Outback 2009-2012 Impreza R 2008-2011 Impreza Sport 2015-2017 WRX 2016 WRX STI 28103-SG000 28103-AG01B: Ensuring Accurate Tire Pressure Monitoring by Adam Walsh

I wasn't quite sure how it would work without programming or anything but the description said it would work for my 2016 Subaru Wrx. So I asked the tire dealer to install them without "waking up" or programming. I was concerned that my TPMS warning light would come on after fitting a new set of tyres/wheels but no! There is no warning light which means these sensors work for my machine without any programming. This was perfect as I wanted to keep my original sensors on my other set of tires/wheels (winter set) and have a different set for the warmer months with my high performance tires. Ideal! Would buy again.
