Available at your local automotive store. Spark Plug Non Fouler PN 42009 ($4.99)
You now need to
drill out 1 of the non foulers using a 1/2" drill bit. When finished this is what it will look like.
Side by Side comparison of the original and now modified non foulers
O2 Sensor inserted in the modified non fouler
Second, unmodified non fouler now installed on modified non fouler
Original non fouler->Modified non fouler->O2 sensor
Fully installed one of my other vehicles, but I did the exact same with my DT setup.
You can use one longer non-fouler which is what I did after the first time I did this, just make sure it is the same diameter for the O2 sensor. Whatever route you go make sure you have a setup for both sides of the exhaust. They also have these on Ebay and other vendors, however they are usually $15+ for the same thing. Up to how much work you want to put in, if drilling is too much.
What this does is it moves the O2 sensor further away so a limited amount of exhaust gets to the O2 sensor, it is a VERY little amount that actually gets to the sensor but as long as it is considerably less than the primary O2 sensor then it wont cause a CEL.
