Spark plugs must be fitted with the correct heat range to optimize efficient combustion and protect the engine from overheating. The Champion N9YC is a relatively hot spark plug with a comparable heat range to the NGK B6ES.
This spark plug is appropriate for 1978-1982 Triumph Models T140E and T140D along with 1972-1975 Norton Commando 750s.
The Champion N9YC has 14mm threads, 19mm thread reach and features a projected tip configuration. The heat range is similar to the NGK B6ES spark plug and is suitable for use on many British twin-cylinder motorcycle engines.
The spark plug fires the fuel mixture charge to create combustion in the combustion chamber. Spark plugs must be clean and free of heavy carbon and oil deposits to provide a strong spark.
The spark plug is threaded into the cylinder head. Sold individually and multiple quantities for savings.
