Detailed Description
Use NGK 4076 when you need a spark plug matched to the listed Kawasaki KX85, KX80, KX100, and KX125 fitments. The plug uses a 1-resistance design, a .75 inch reach, and a heat range of 11, with fitment notes calling for specific gap settings depending on the model and year. For buyers searching for a Kawasaki KX80 spark plug or a Kawasaki KX125 racing spark plug, this part number 4076 provides the specified configuration in one application-specific part.
NGK’s OE supplier background and broad motorsports coverage support consistent ignition performance across the listed off-road applications. If you are replacing a worn spark plug on a Kawasaki KX85 or KX100, part number 4076 is the cataloged match for the exact year and model combinations shown below.
What It Is Used For
- Restoring ignition performance when the existing plug is worn or fouled
- Addressing hard starting caused by an incorrect or degraded spark plug
- Correcting misfire or weak spark conditions in listed two-stroke applications
- Replacing a plug with the wrong heat range or gap specification
- Maintaining proper combustion in racing and off-road use
Installation Notes and Tips
Verify the exact year, model, and fitment note before installation, since several listings require a specific gap setting such as 0.030 or 0.032 inches. Confirm the plug seat type, thread diameter, and reach match the engine specification before tightening. Use the cataloged gap for the application and inspect the ignition system if the old plug shows signs of repeated fouling.
