NGK Iridium Stock Heat Spark Plug Box of 4 (LZTR5AIX-13)

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.
