Champion N-Series Spark Plugs
Champion N-series racing spark plugs have 14mm threads and a 3/4 inch reach. They take a 13/16 inch (21mm) wrench. We offer regular tip (CH NxC) and projected tip ("J Gap", CH NxYC) designs in a variety of heat ranges. An R in the part number indicates a resistor plug for RFI suppression.
Formula Ford 1600 engines with the original cast iron head use the CH N6YC plug.
