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.\u003c\/p\u003e\u003cp\u003eThis 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.
