The appropriate NGK spark plugs are designed solely for use in automotive, motorcycle, marine, horticultural, agricultural, commercial, industrial and stationary engines. NGK spark plugs should not be used in aircraft engines. Resistor plugs should always be used where they are recommended by the manufacturers. The use of non-resistor plugs could, in some cases, result in interference with and/or damage to electronic components. http://www.ngk.com.au/
