The threads on the stem of one of the original sensors sheared off and caused a constant air leak. The sensor was removed and replaced with a traditional stem. I want to replace this with a new sensor; however, I have been told that the first gen sensors are crap and will probably fail as well. I am looking to replace all four sensors but would like to know which sensor to use. The OEM? Is there a better aftermarket? Can anyone provide thoughts and experiences?
