NGK Spark Plug
CAL188 - Augusta,GA 2018 KX 450 and KX 250 "Great spark plug. Change on both bikes after 30 hours on KX 250 and 50 hours on KX 450. Both plugs looked great. For the price its makes since to change out with new even if they look good. Don't ever skimp on maintenance when comes to motocross."See all reviews for this product
NGK Iridium IX Spark Plugs
Timmay - Ca Check spark gap!!!!!!!!! "These are a fine plug, however, many think these come pre-gapped.. If your manual calls for 0.20 then I guess it is, my manual calls for .38-.43 ... 2015 Sportster.. I gapped accordingly and the throttle response is quite noticeable and gas mileage 2 mpg improvement.. CHECK THE GAP!!"See all reviews for this product
