Description
Drag Specialties - Spark Plug fits '75-'84 Shovelhead (Hot), '84-'99 Evolution Big Twin Models
Hot Spark Plugs:
- Designed for: Optimal performance in engines that operate mostly under low to moderate load conditions.
- Characteristics: Have a longer insulator nose that retains more heat, helping to prevent fouling when the engine is operated at lower temperatures for extended periods.
- Best Used: In scenarios where the engine runs at lower speeds, such as city riding or short trips that do not allow the engine to fully warm up. They can help keep the spark plug cleaner by burning off deposits.
Features:
- Plugs have a unique look with a black ceramic body and bold red logo/script
- Insulator is made of 95% pure alumina, features strong resistance to heat shock and superior insulation
- Multi-rib design of the insulator eliminates flashover
- Nickel-plated housing prevents oxidation and corrosion
- Multi-layer gaskets and heat crimping process ensure a leak-free, gas-tight seal
- Copper core electrode prevents oxidation and corrosion, has good electrical and heat conductivity and creates long spark plug service life
- Sold in pairs
