Don't waste money on mil eliminators
If your vehicle has a mid-pipe without catalytic converters then chances are your CEL is on. Dont waste your money on MIL eliminators. Simply install these into the rear o2 sensor bungs then install your o2 sensors. This will move your o2's out of the exhaust stream and turn your CEL off. This will save you a ton of money and their will be no electrical parts that can fail down the road. In my opinion this is a perfect match with any off-road exhaust systems. This would also be a good fix for passing state emissions testing. All in all I feel thisbis a great product for the money and I will highly recommend using for every day use. Thanks advance!

No more P0420 code, perfect fix until you can replace Cat
Drill the smaller opening through with 1/2 bit on first piece, screw in O2 sensor to it, screw together with second undrilled piece then screw into exhaust pipe after catalytic converter. 2009 3.8l VW Routan SE, Dodge Grand Caravan SXT, Chrysler Town and Country Touring.

O2 spacer for 2011 mustang
No cats on my 2011 Mustang threw codes P0420 & P0430. I used two of these spacers for each of the two rear O2 sensors. Drill the first spacer with 1/2" drill bit so the end of the O2 can pass through it. Then screw the next spacer on the end so the little holes restricts the fumes from fully reaching the sensor. This way, your sensor will think there is a cat and get the proper readings as if there was a cat and your car will pass emissions. I took mine to a kiosk so I could self test and not have someone looking for the cats. Worked great. Took one week and 340 miles to get to "readiness" with all sensors ready for emissions. On Ford, turn key on, check engine light will turn on and stay on. If after 15 seconds, the check engine light blinks 8 times, you are NOT ready for emissions. Keep driving and checking until the light stays on continuously and doesn't blink during this test and then take to emissions. See attached pics. I used the crush washers between each spacer to seal but not shown in the pic I did for mockup.
Bottom Line Yes, I would recommend to a friend
Love these things!
Verified Buyer -
I love these because when I have a check engine light come on for a post cat converter i simply drill out the extra material inside of this to then extend the o2 sensor bung in the exhaust pipe. It will keep the sensor out of the heat that is normally generated by a modified exhaust setup in my off-road use only vehicles;)
Blah blah blah

I used them for O2 sensor spacers and they worked great.
