Don't waste money on mil eliminators

Comments about Dorman - Help Spark Plug Non-Foulers - 18mm Gasket Seat:

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!

          Used this non fouler on a Chevy Cavalier to grab the stripped threads deeper in the pipe than the oxygen sensor could. I drilled out the center hole to open the path to the sensor ports. Works and passed all tests.
