Genuine ACDelco spark plugs: conventional plugs like R45TS and CR43TS, and platinum and iridium plugs like 41-962 and 41-109. Where GM gives the plug its own part number, the listing shows it, and searching the GM number finds the plug. See the ACDelco to GM number chart.

Packs of 1, 2, 4, 6 or 8, or any amount from 1 to 48. Check the number on your old plug or your owner's manual before ordering.

Free standard shipping on orders over $150; in-stock parts ship the next business day.
