I have a 1998 Z28. I want to get the updated version of the knock sensors. I am replacing the sensors and want to make sure I get the right ones as I hear some are over sensitive. They said they had 1st release with locating tab or 2nd release without locating tab. what does that mean? is the 2nd release what I need? will they fit or do I need something else to make them work?
thanks
oh and I have a ls6 intake if that matters.
