Spark Plug - Genuine ACDelco R44TS

Product Description

Brand-new genuine ACDelco R44TS OEM spark plug. This was the original stock spark plug with the same heat range that was factory installed on new 1984-1987 Buick Grand Nationals, Turbo Regals and 1987 GNXs.

This plug is designed to keep the center electrode at the optimum temperature to burn off deposits that may otherwise lead to misfires and lost efficiency on stock and mildly modified engines that are primarily used to idle and drive around town.

This genuine ACDelco part will ship in its original box as pictured.

Recommended gap = 0.035"
