series. Specifically, the "38" series in their catalog (such as parts like 38-1958MPG) identifies high-performance ignition wire sets designed for specific vehicle engine configurations.
The primary innovation in the line is the use of a solid stainless steel inner core . Unlike standard carbon-core wires that rely on resistance to suppress noise, these wires feature 0 Ohms per foot of resistance .
These are typically pre-assembled with stock-style distributor terminals and spark plug boots, allowing for a "plug-and-play" replacement of OEM wires. HMM Gracel Set 38 Part 1 Mpg part
The improved ignition efficiency often results in measurable increases in both horsepower and torque . 3. Physical Specifications (Set 38 Series)
Below is a detailed report on the technical specifications and performance claims for this specific part series. series
High-temperature silicone boots and jackets designed to withstand extreme engine bay heat.
Provides a stable path for current, which Granatelli claims leads to a "hotter" spark for more efficient combustion. 2. Performance and Efficiency Gains Unlike standard carbon-core wires that rely on resistance
The zero-resistance design ensures that the full energy of the ignition coil reaches the spark plug without power loss.
