NGK Iridium Racing Spark Plugs R7438-8 (MPN 4905) - Set of 4
$610.88
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
NGK Iridium Racing spark plugs (R7438-8) are engineered to withstand the extreme cylinder pressures and high thermal loads found in professional motorsport and high-performance tuning applications. Designed for durability and consistent ignitability, these plugs utilize specialized center electrode configurations to ensure a reliable spark under the most grueling racing conditions. The trivalent metal plating provides superior anti-corrosion and anti-seizing properties, protecting your cylinder head threads during frequent plug changes.
- Iridium Center Electrode: Engineered for high melting points and maximum conductivity to maintain a stable spark.
- Trivalent Metal Plating: Delivers exceptional anti-seizing and anti-corrosion protection for easier installation and removal.
- Pure Alumina Silicate Ceramic: A high-grade insulator that provides superior structural strength and optimal heat transfer.
- Copper Core: Assists in rapid heat dissipation to prevent pre-ignition and electrode overheating.
- Triple Seals: Ensures combustion gases cannot leak past the shell, maintaining engine compression.
This set includes four individual spark plugs. Manufacturer Part Number: 4905.
