Champion Premium Spark Plug
The Champion Premium Spark Plug provides a 14mm thread with a fine-wire nickel center electrode and a heat range of 19. This plug delivers quick, clean ignition to help engines start smoothly while keeping emissions lower. Its profile is intended for lawn and garden machinery along with similar engine types, offering an OE-level replacement that slots directly into the existing cylinder head. The focused spark path converts electrical energy efficiently, giving the ignition system a consistent discharge even in equipment stored for long periods. The build approach provides cleaner combustion and steadier engine rhythm during continuous mowing or small-engine equipment cycles. The Champion 861ECO is chosen for engines that benefit from reliable spark under frequent start-stop patterns.
