What makes them stand out?

Angled Ground Strap Electrode

These spark plugs use an angled ground strap electrode, which:

• Protects the internal ceramic

• Improves high-temperature resistance

• Provides a more stable spark under high pressure

• Suitable for aggressive loads

Why Racing spark plugs?

For IS38 configurations and increased boost:

• Cylinder pressure increases

• A stronger and more stable spark discharge is required

• OEM spark plugs can start to "blow out" under high load

The R7438-8 is designed for racing use and higher thermal loads.

Advantages

✔ More stable spark discharge under high pressure
✔ Better insulator protection
✔ Reduced risk of misfire with tuning
✔ Higher resistance in track conditions

Important

These are competition spark plugs – designed for cars with increased power.
They are not necessary for standard or lightly tuned daily configurations.
