The pricing on 2010 and 2011 sensors is higher, currently at $80 per sensor, or $88 including the valve stem. The older 07-09 sensors will *not* work on 2010 and 2011 cars.
Unfortunately the web site isn't set up to accept orders for TPMS sensors at this time. I'd be happy to help over the phone or via email.
One way to get around the web problem would be to add a complete set of wheels to the cart, then the site will allow you to add the sensors. Next, delete the wheels from the shopping cart, so that all that will be left is the sensors.
Just refer to "Gary/e90post" as your previous contact towards the end of the order.
