Champion QC12PEP Double Platinum Spark Plug - 956M

Platinum tipped center electrode and platinum pad on ground electrode provide long life and minimal wear. Tapered electrodes create a sharper spark focus and reduce quenching. Electrodes use heat-active alloy to reach operating temperatures quickly and maintain stable temperatures under varying engine loads. Triple sealed interior and copper core reduce failure due to heat and stress.
