How many spark plugs are in this box?

This box contains four (4) NGK Iridium IX spark plugs. This is typically enough for most 4-cylinder engines, but you'll need to verify the number of spark plugs your specific vehicle requires.

What makes iridium spark plugs better than standard ones?

Iridium is a much harder and more durable metal than platinum or nickel alloys used in standard plugs. This allows for a finer electrode tip, which requires less voltage to create a spark and results in a stronger, more consistent spark for improved combustion.

Do these spark plugs come with anti-seize pre-applied?

NGK spark plugs are manufactured with precise tolerances. While these plugs feature trivalent metal plating for anti-corrosion and anti-seizing properties, it is always recommended to refer to the vehicle manufacturer's service manual or NGK's installation guidelines for specific anti-seize compound recommendations during installation.

Product Details

When you're looking to get the most out of your engine, especially if it's been modified or you're aiming for better overall performance, upgrading your spark plugs is a smart move. These NGK Iridium IX plugs are designed to give you a more consistent and powerful spark, which can lead to better acceleration and improved fuel efficiency. They're built with a fine iridium tip, known for its durability and ability to maintain a sharp spark over time, even in demanding conditions. This makes them a solid choice for many Chrysler, Dodge, Jeep, and Volkswagen vehicles from the late 90s through 2011.

What sets these plugs apart is the iridium fine wire center electrode. Iridium is a very hard metal with a high melting point, making it ideal for today's hotter-running engines. The tapered cut on the ground electrode also helps with starting and idling, smoothing out your engine's performance. Plus, the trivalent metal plating on the plug body helps prevent corrosion and makes them easier to remove down the road, which is always a nice bonus during maintenance.
