Osculati 47.558.16 – NGK CR6E Spark Plug
The Osculati 47.558.16 includes the NGK CR6E spark plug, a resistor-type marine spark plug used in small to mid-sized 4-stroke outboards. It features a compact 10 mm thread and extended 19 mm reach, with a 16 mm hex for easy access in tight engine compartments. The 5 kΩ built-in resistor ensures full RFI suppression, protecting sensitive marine electronics including GPS, sonar, and radios.
With a medium heat range (6) and a copper-core, projected-tip design, the CR6E provides excellent combustion efficiency, cold-start reliability, and reduced fouling in slow-speed operation. It does not have a direct Champion equivalent but is widely adopted by OEMs in modern 4-stroke platforms.
