Put More Ignition Energy Where It Matters

Conventional spark plug wires can introduce resistance between the ignition source and the spark plug. Granatelli's 0 Ohm technology is engineered to minimize that resistance and maximize the transfer of available ignition energy.

According to Granatelli's product specifications, these wires can provide up to 400% more power to the spark plug compared with stock wires, depending on the application. Performance gains will vary based on the engine and overall combination.

Performance Notice: Horsepower improvements are application-dependent and will vary based on engine configuration, ignition system, tuning and other modifications.

Patented 0 Ohm Technology

Granatelli's 0 Ohm ignition wire technology is protected by U.S. Patent #7,185,622. The design combines extremely low resistance with noise suppression technology to help maximize electrical energy transfer from the ignition source to the spark plug.
