I hope you guys don't hate all my questions. I have just about tuned up everything on my truck, except for the 02 sensors. My truck has 100k miles, and I don't know when they were changed. I have a magnaflow exhaust, stock cats. How much toll does it take on the mpg.
Do I need to order two of them for replacements?
