Denso 3106 S29A Spark Plug

Denso spark plugs are 100% pre-fired to assure the highest quality possible. Surface discharge increases ignitability and fouling resistance. Machine rolled threads prevent seizing or cross threading during installation and removal. Purified alumina powder insulator provides exceptional strength and thermal conductivity. Five rib insulator prevents flashover. Copper-glass seal bonds center electrode and insulator for a gas-tight seal.
