Be the first to write a review

NGK R-7438-9 are ideal for the Toyota V6 engines used in the Evora and V6 Exige race cars

Spark plugs used for racing must withstand especially hard stresses with some engines revving in excess of 10,000 rpm.

Temperature, pressure, and vibrations in the combustion chamber are so immense that conventional ground electrodes could break or melt.

NGK Spark plugs are used in all types of race engines for many years and are trusted by McLaren Mercedes, Ferrari F1 teams and the Qatar M-Sport WRC and MotoGP

Specially designed ground electrodes, the most extreme form with a ring-shaped ground electrode and the zinc dipped shell prevents corrosion while the triple gasket seal eliminates combustion gas leakage.

Special configurated insulator nose improves throttle response and prevents fouling with corrugated ribs on the insulator to prevent flashover.

One of the world’s hardest metals, the precious metal iridium starts melting at a temperature of 2450°C and is therefore very resistant to spark erosion.

The plug includes a solid copper core for a greater spark.

Fine-wire centre electrodes provide better sparking and enhanced ignitability and Fine-wire ground electrodes further improve the ignitability of the plug.

NGK Race Iridium spark plugs will give you more power and torque over any other spark plug.

PRICE IS FOR 1 SINGLE SPARK PLUG
