Comments about Dorman - Help Spark Plug Non-Foulers - 14mm Gasket Seat Long Reach:

I have a 1996 Mazda Protege with 150,000 miles. I replaced the plug wires and plugs. I noticed a cylinder with oil in it so I purchased the non-fouler thinking I would use it until I had a chance to make the correct repair. After driving about 3 miles the porcelain part of the plug blew out leaving the plug base in the non-fouler. This happened 2 more times with about 8 miles being the greatest distance driven before it happened. I removed the non-fouler and have been driving the car since with the occasional fouled plug.

    • A:

      Exactly. It extends the plug distance from the oil, so it won't foul out and not fire.
