The NGK MOD ignition coil set for Audi A4, A8, S6 and RS6 applications increases output using custom primary and secondary windings for stronger spark energy. PET housings, vacuum-sealed epoxy resin and high-temperature silicone COP boots provide dielectric strength and thermal resistance. Tuned to pair with NGK spark plugs, these coils were developed and tested in NGK’s ISO 17025 lab for reliable high-output service.
