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

      This simple device allows the spark plugs to remain clean and free of oil on engines that burn oil and that would otherwise foul the plugs. Used a few of these on my 1948 Buick that is overdue for a ring job. Plugs stay clean with the non-foulers. However use a plug a few heat ranges COOLER because the non fouler makes the plug run hot besides keeping the oil off the plug. If you use a hot plug with the non-fouler the plug may overheat and cause pre-ignition. Used with care however they work perfectly...just be sure to use the correct heat range plug with it.

          Hi Ken, this spark plug non-fouler is not an ideal part for your 1946 Jeep Willys CJ-2. Currently, I am unable to locate an exact spark plug non-fouler for your vehicle online. However, if you could please visit the nearest Advance Auto Parts store one of our Parts Pros will gladly assist you.
