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!!

I use these in my KTM 300XC. Great plugs. Last a long time, engine runs great and have never had one foul out.
Great performance & mileage
item is as listed
Bought as a update for my Husaberg to aide in starting! Works awesome, spark is so much stronger!
New plugs in the "ol" Girl (1995 ZX11) and she runs smooth and sweet! Thanks again!!!
confused on how to find size
I replaced the OEM plugs with these about 6mo ago, the difference was immdiate, when starting her up. I've had no complaints since.
NGK’s spark plugs has always been reliable for all my motorcycles. NGK’s IRIDIUM IX PLUG - is a great spark plug if you want a hotter plug that’s dependable and lasts. Worth every penny!
Great stock upgrade for my warrior
