Spark Plug Non-Fouler

A spark plug non-fouler shrouds the end of the spark plug to prevent oil contamination inside the cylinder. If your vehicle is burning a lot of oil, that means that your spark plugs are at risk of being fouled by the oil in the combustion chamber. If this is the case, the spark plugs may need to be cleaned or replaced much more regularly than usual. If your car starts to misfire and your spark plug looks burned and damaged, then a spark plug non-fouler insert may be a temporary fix. Purchasing and installing a non-fouler might help extend the life of older engines that burn an excessive amount of oil. At O'Reilly Auto Parts, we carry spark plugs, non-fouler inserts, and other parts to keep your car, truck, or SUV on the road.
