Product Details

NGK Racing Spark Plugs deliver OEM-quality performance and extended service life for demanding applications. These platinum spark plugs feature advanced dual-platinum construction for superior durability and consistent ignition.

Key Features:

  • Dual platinum design with platinum on both the fine-wire center electrode and ground electrode
  • Extended service life compared to standard copper plugs
  • Enhanced protection against plug wear and gap erosion
  • Original equipment specification on many late model vehicles
  • Fine-wire center electrode for improved ignitability
  • Sold as a 4-pack for convenient multi-cylinder service

NGK's platinum technology ensures stable spark performance over the life of the plug, reducing the need for frequent replacement. The platinum ground electrode provides additional resistance to the harsh combustion environment, maintaining proper gap and firing efficiency.

Great thanks

This was an awesome experience. I thought I was going to have to have 2 days of car work due to not ordering in time, but apparently what I needed, shipped from Commerce City (and I live in Colorado) and it showed up in 2 days during the busiest ship time of the year. Also was the cheapest price by quite a bit.

Fast delivery.

Glad there is next day shipping available!
