NGK G-Power Spark Plug Box of 4 (BPR5EGP)

The fine wire platinum center electrode in these NGK G-Power spark plugs is a key detail that matters for your engine's performance. This design choice means less voltage is needed to create a spark, which can lead to quicker starts, better acceleration, and improved fuel economy compared to standard nickel alloy plugs. These are a solid option for many vehicles, offering the benefits of platinum at an economical price.

NGK builds these plugs with a pure alumina silicate ceramic insulator, which is strong and helps transfer heat away from the firing tip. The ground electrode has a trapezoid cut to reduce the area where the spark can be "quenched" or extinguished, helping to ensure a more complete burn. For added durability and to prevent seizing in the cylinder head, the metal plating used is a trivalent type, offering good corrosion resistance. The copper core also aids in heat removal, and triple seals are used to prevent any compression leaks.

This set comes with four spark plugs, which is the correct quantity for many common 4-cylinder engines. They are a good choice for upgrading older vehicles that originally came with nickel alloy plugs, or as a cost-effective replacement for existing platinum plugs.
