What is the difference between the 30-4100 and the 30-4113 (besides $100). The 30-4100 says it's a 6 in 1 with a bunch of different faces for it. The others say display only (does that mean it doesn't come with a sensor???)
Also what does UEGO stand for? Oops - I found this "Universal Exhaust Gas Oxygen Sensor".
