Powerdex AFX Sensors I am looking at the sensor I just pulled from my downpipe out of my original kit. Does'nt look too bad but I have a fresh build and wanna play it safe. The part number is NTK 24302 and they are a around $109 on oxygensensor.net. Looking around and summit has a similar 5 wire NTK sensorNGK-24313 for over $250. What is the difference? I don't know much about that website not sure if anyone has a reputable vendor that sells these replacements for a reasonable price. Thanks in advance!
