I bought the Titan brand from OEWheels. The guy at oewheeels told me they are as good as the more expensive ones they sell. I bought them in Jan 2014 and I think the four were $136.00. Work perfectly and show 96 months of life on my Durametric. The oem original sensors lasted from the August 2006 build date to January 2014 when one failed. The other three showed several months left. Were on a 2007 Carerra S. No reason to spend a ton of money on this item.

At the risk of piling on ... get the OE Wheels and enjoy all that cash u just saved. Mine have been working perfectly.
