Denso Iridium TT Spark Plug IKH20TT

Denso Iridium TT Spark Plugs (like this IKH20TT) combine iridium and platinum with Denso's 360° laser-welding process to machine-engineer a spark plug capable of over 150,000 kilometres of driving. The premium design technology allows for spark minimisation and ignitability maximisation, meaning better power transference, greater torque and improved fuel economy for your vehicle.
