What sensors did you buy? I'm looking at doing this to mine as well. I lost approx 12% in mpg all of the sudden and no reasons yet why. I've done the basic and normal maintenance and am lost for things to try now. I'm not getting a code but it could be my o2 sensor is starting to fail. I've found both denso exact replacements for close to $65 each and I need 4 rt? I've also found a universal ones for $35 each.

 

Good tip. Some Denso sensors actually come with anti seize in the box. Also, if you have the time in the future, always get your sensors online. They are usually almost half price over a traditional auto parts store. Amazon or Rock Auto or even eBay from a reputable seller.

 

I actually bought 2 bosch sensors at Autozone, so far they are working great.

 

I agree with the online searching. As long as you cross reference with Densos website Amazon is a great source.

 

Long Drive + Liquid Wrench + O2 Socket = WIN !!!

 

Nothing breaks rust like heat!
