NGK Racing R7448A-8 Spark Plugs - Heat Range 8 (Box of 4)

NGK Racing spark plugs are purpose-built for the most demanding competitive environments, engineered to withstand the extreme thermal loads and mechanical stresses of high-output racing engines. The R7448A-8 features specialized electrode configurations that prioritize ignitability and durability in conditions where standard plugs often fail. By utilizing a copper core deeply inserted into the center electrode, these plugs provide rapid heat dissipation to prevent pre-ignition and ensure consistent performance throughout the powerband.
