# NGK Spark Plugs: Harley-Davidson & American V-Twin ## NGK Spark Plugs: Harley-Davidson & American V-Twin 384 spark plug applications from NGK's catalogue, for the machines we supply parts for. Each line gives the plug NGK specifies, the premium upgrade where one exists, and the electrode gap. **Plug codes shown as links go straight to that plug on our shop.** Models that take the same plug are listed together on one line — find your model on the line for your engine size — the plug and gap on that line apply to every model listed there. Years are shown in brackets after each model where NGK lists them. **Check the gap before you fit.** Plugs are not always gapped correctly out of the box, and the wrong gap causes misfire and hard starting. Where a resistor plug is specified, fit a resistor plug — a non-resistor substitute can interfere with a tacho, ECU or engine electronics. - [Harley-Davidson](#harley-davidson) - [Victory (Polaris)](#victory-polaris) -

The digit in the middle is the heat rating — a **higher number is a colder plug**, which is the opposite of most other brands. An **R** after the first letters means a resistor plug. Codes ending **IX** are the Iridium IX range and **G**, **GP** or **P** the platinum ranges, both direct upgrades with a finer centre electrode. Where NGK specifies the solid-terminal build of a plug we show the base code, which is the one we stock — tell us if your leads need the solid-terminal version. Do not substitute a hotter or colder plug to cure a running problem. A plug reading the wrong colour is telling you about the fuel, ignition or oil — changing heat range hides it rather than fixing it. ### Other machines - [Honda & Kawasaki Motorcycles](/pages/ngk-spark-plugs-honda-kawasaki-motorcycles) - [Yamaha & Suzuki Motorcycles](/pages/ngk-spark-plugs-yamaha-suzuki-motorcycles) - [Off-Road, Enduro & Trials Bikes](/pages/ngk-spark-plugs-offroad-enduro-motorcycles) - [European Road Motorcycles](/pages/ngk-spark-plugs-european-motorcycles) - [All Other Motorcycle Makes](/pages/ngk-spark-plugs-other-motorcycles) - [ATVs & Quad Bikes](/pages/ngk-spark-plugs-atv-quad) - [All Other ATV Makes](/pages/ngk-spark-plugs-atv-other-makes) - [All reference charts](/pages/resources) ### Not sure which plug you need? Model families ran across several specifications and the year or engine number usually decides which line applies. Ring [0412 532 984](tel:+61412532984) with your bike and we will confirm the plug, the gap and how many you need.
