Review on TEKTON 3/8 Inch Drive x 7/8 Inch Offset Oxygen Sensor Socket - 6-Point, Model 47749 by Victor Kakaruk

Good. This item saved the day on my 2003 Elantra. Hyundai corrected the incorrect top track width angle on the 2004 model, but pre-2004 this is a bottleneck. To the person who mentioned the hose clamp idea, THANK YOU. I would buy these 3 tools below. If your time is more important than your money, get all three at once. If your money is more important than your time, I would rate the benefit as follows. 1-3.1 TEKTON 47749 "Short" 2 TEKTON 4929 Deep Well with Socket 3 Bovidix 0681922 Cap Wrench, Metric - 19 x 22mm (or similar) (Least useful tool for a really stuck sensor, but great for after the first one breakage rust and tightening) 47749 is best for hard-to-reach areas and allows for the installation of a hammer or impact wrench. But a deep hole is better for full power with an impact wrench. I was able to remove the top sensor and the bottom sensor. The deep well was best for the top. and 47749 was better for the bottom. However, this only depends on the settings of your machine. Much luck.
