FAQ:

Q: What is the purpose of a non fouler on an engine?

A: The non fouler could serve as a temporary fix for the engine problem. They are designed to prevent the spark plugs from getting damaged and to fix spark plug fouling if the engine has run too rich or if there are some oil issues. The defouler is made up of high quality steel that are corrosion resistant making them effective for their role.

Q: What is a spark plug non fouler and how does it work?

A: So what is a Spark Plug Non Fouler? A spark plug non-fouler is a device that screws onto the spark plug and acts like a sleeve for the plug. It has a small hole enough for the gas vapor to pass through to ignite and move the engine while keeping the oil or other substances out so it doesn’t foul the plug.

Q: Is it illegal to use spark plug non fouler for O2 sensor?

A: But some techs have been using Spark Plug Non-Fouler for O2 Sensors for a cheaper and a temporary fix of the P0420 code/Catalyst Inefficiency Code instead of replacing the catalytic converter or other more costly repairs. This is illegal for some states, especially if you are using it to pass an emission test.

Q: How do I choose the best non-fouler for my car?

A: Speak to a team member about the best non-foulers for your vehicle. With different brands and prices, one may work better for your engine than another. If you’re burning or leaking oil, be sure to keep a quart or two stocked in your car along with shop towels and a funnel.
