Product Details
This is a box of four NGK Iridium IX spark plugs, part number DR7EIX. These plugs are designed to give you a more consistent spark, which can lead to better acceleration and improved fuel efficiency. The fine iridium tip is very durable and can handle the higher temperatures found in many modern engines. They also feature a trivalent metal plating that helps prevent corrosion and seizing, making them easier to remove next time around.
The iridium alloy used in the center electrode has a very high melting point, making it well-suited for today's engines. The tapered cut on the ground electrode is a small detail, but it helps with starting, idling, and throttle response. These plugs are a good upgrade over standard nickel alloy plugs and are suitable for modified or high-performance applications.
