NGK Iridium IX Spark Plug Box of 4 (BR10ECMIX)

When you're looking to get the most out of your 2003-2006 KTM 85 SX, especially if it's been modified or you're aiming for peak performance, upgrading your spark plugs is a smart move. These NGK Iridium IX plugs are built with a fine iridium tip, which is known for its extreme durability and ability to maintain a consistent spark, even in high-temperature engines. This means you can expect better acceleration and improved fuel efficiency compared to standard nickel alloy plugs.

The iridium alloy used in the center electrode is significantly harder than platinum, offering six times the durability. This translates to a longer service life and reliable performance over time. The tapered cut ground electrode also helps with easier starting, smoother idling, and a more responsive throttle. Plus, the trivalent metal plating on the plug body helps prevent corrosion and seizing, making installation and removal a bit easier down the road.
