Overview
NGK 1111 is a standard spark plug built for a wide range of motorcycles and small-displacement engines. It uses a copper center electrode core, nickel center and ground electrode tips, and a flat seat design for straightforward service replacement.
Compatible with classic Kawasaki, Yamaha, Suzuki, Honda, Harley-Davidson, Benelli, and Scorpion applications, this NGK spark plug supports direct replacement needs where the specified heat range and gap match the engine requirements. Part number 1111 is also identified as B7ES.
Key Features
- Standard spark plug design for routine ignition service
- Copper core center electrode for stable conductivity
- Nickel electrode materials for common service applications
- Flat seat construction
- Removable nut terminal for flexible connection style
- Part number 1111, also listed as B7ES
Detailed Description
NGK 1111 is a conventional spark plug engineered around proven service-part construction. The 14 mm thread diameter, 0.75 inch reach, 13/16 inch hex size, and 1 resistance rating make it a practical replacement for engines that call for this specification set. The pre-gap is .032, and the manufacturer heat range is 7.
This spark plug is used across many older motorcycle and off-road applications, including Kawasaki KZ400, Kawasaki KZ650, Yamaha DT100, and Suzuki TS250 fitments. If you are servicing a Kawasaki KZ440, Yamaha TY175, or Honda XL175, verify the required gap and seat type before installation. Part number 1111 appears in interchange listings and is commonly referenced as B7ES.
Common Uses
- Hard starting caused by worn or fouled spark plugs
- Misfire from incorrect gap or degraded electrode condition
- Weak ignition performance in older carbureted engines
- Routine tune-up replacement for specified applications
- Restoring consistent spark delivery in serviceable ignition systems
Installation Notes
Confirm the engineโs required heat range, thread diameter, reach, seat type, and gap before installation. Set the gap to the vehicle specification when needed, and inspect the plug wire or cap condition during service. Use the listed fitment notes for application-specific gap guidance.
