NGK IX Iridium Spark Plug Box of 4 (BPR6EIX)

NGK is well-known for making reliable ignition components, and their Iridium IX spark plugs are a solid choice for many vehicles. These plugs are designed to give you a more consistent spark, which can lead to better acceleration, improved fuel efficiency, and longer life compared to standard plugs. They are a great upgrade for modified engines or for anyone looking to get more out of their ignition system.

The key to these plugs is the fine iridium tip on the center electrode. Iridium is a very hard metal with a high melting point, making it durable enough for today's hotter-running engines. This fine tip also helps create a stronger spark and resists fouling, meaning you get reliable performance and easier starting, idling, and throttle response. The ground electrode is tapered, which further helps with ignitability. Plus, the trivalent metal plating on the plug body helps prevent corrosion and makes them easier to remove down the road.

This set comes with four spark plugs, enough for most 4-cylinder engines. They fit a wide range of vehicles, from classic BMWs and Audis to more modern sports cars and even some powersports applications.
