This set of 6 Dinan Iridium spark plugs is an excellent upgrade for tuned B58 and S58 engines. Made from Iridium for optimal temperature and pressure resistance, these colder (grade 9) spark plugs are designed to deliver a more powerful spark while dissipating heat more efficiently, regardless of the fuel type used. Compatible with the 140i / 240i / 340i / 440i and the M3 G80 / M4 G8x / M2 G87 / X3M F97, these 1 step colder spark plugs are perfect for both stage 1 tuned or heavily built engines.
