What is the purpose of a spark plug non-fouler?
A sparking plug non-fouler may be a device that screws onto the sparking plug and acts as a sort of a sleeve for the plug. It’s a little hole enough for the gas vapor to ignite and move the engine while keeping the oil or other substances out so it doesn’t foul the plug.
What does O2 spacer do?
The spacer puts the O2 sensor out of the exhaust flow. This tricks the ECU into thinking that the cat is working when you don’t have one or have a high flow one.
How does a Defouler work?
you install the defouler on the lower one where it meets up to the exhaust. That one’s only purpose is to tell whether the catalytic converter is working or not. The defouler pulls the sensor out of the exhaust gas stream and tricks the computer into thinking you you still have a functioning cat.
Are O2 sensor spacers universal?
Notes: Fitment is UNIVERSAL – please check for available space for installation prior to purchasing. For use ONLY in the Secondary (post cat, downstream) O2 sensor. Emissions compliance not guaranteed.
How do you install a spark plug on a non fouler?
How To Install Spark Plug Non-Fouler In Your Car?

This is illegal for some states, especially if you are using it to pass an emission test. Others have concluded that 2 spark plug non foulers is not going to work and you’ll still end up with the MIL light on as the ECM will be able to detect that the O2 sensor is not active.
What is the purpose of a non fouler on an engine?
The non fouler could serve as a temporary fix for the engine problem.

The defouler is made up of high quality steel that are corrosion resistant making them effective for their role.
What does the O2 sensor ammount do?
What this does is it moves the O2 sensor further away so only a limited amount of exhaust gets to the O2 sensor, it is a VERY little ammount that actually gets to the sensor but as long as it is considerably less than the primary O2 sensor then it will not cause a CEL or Check Engine Light.
