The main difference between a CR43TS and an R45TS spark plug lies in their heat range and design. The "C" in CR43TS indicates that it has a copper core, which can provide better heat dissipation, while the "R" in R45TS signifies that it has a resistor, which helps reduce electromagnetic interference. Additionally, the numbers indicate different heat ratings, with the R45TS being slightly hotter than the CR43TS, affecting their performance in various engine conditions. Choosing the right plug depends on the specific requirements of the engine.
