The Spark Plug 4162/4 Copper by AUTOLITE is a high-quality product designed to enhance the performance of a wide range of motorcycles. With a copper-glass seal that bonds the insulator, terminal post, and center electrode together, this spark plug ensures the full required voltage at the spark gap, creating a gas-tight seal that is 100% leak-proof. The multi-rib insulator reduces the danger of “flash-over,” while the one-piece terminal post adds strength to the overall structure.

Additionally, the resistor in the Spark Plug 4162/4 Copper reduces radio frequency interference (RFI) and electrode erosion, ensuring a smooth and consistent spark. The cold-formed steel shell with precision-rolled threads provides durability and reliability in all conditions. The full copper core electrode further enhances performance, making this spark plug a top choice for motorcycle enthusiasts.

One of the key features of the Spark Plug 4162/4 Copper is its compatibility with a wide range of motorcycle models, including Aprilia, BMW, Buell, Ducati, Harley Davidson, Honda, Kawasaki, KTM, Suzuki, Triumph, and Yamaha. This versatility makes it a convenient option for riders who own multiple bikes or those looking for a reliable spark plug for their specific model.

In conclusion, the Spark Plug 4162/4 Copper offers exceptional performance, durability, and compatibility, making it a valuable investment for motorcycle enthusiasts looking to optimize the performance of their bikes.
