NGK Iridium/Platinum Spark Plug Box of 4 (LKAR8AI-9)

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a prime example of that. These plugs are built to last and provide a strong, consistent spark, which is crucial for your engine to run smoothly. They are designed as an OE replacement, meaning they meet the original equipment specifications for many motorcycles and ATVs, ensuring they fit right and perform as expected.

What sets these apart is the combination of iridium and platinum. The fine wire center electrode uses an iridium alloy, which has a very high melting point and offers excellent durability, lasting about six times longer than platinum. The ground electrode features a platinum pad, which helps it wear evenly, especially in modern ignition systems. This design helps ensure a stable spark and reliable starts, even in high-performance engines. The pure alumina ceramic insulator also helps transfer heat away from the plug, preventing it from overheating, while the trivalent metal plating on the body helps prevent corrosion and seizing during installation or removal.

This box contains four spark plugs, which is the correct quantity for many multi-cylinder applications. They are a solid option if your vehicle originally came with fine wire iridium alloy plugs and you're looking for a long-lasting, dependable replacement. You'll find these are a popular choice for vehicles like the KTM 450 XC-W and Husaberg FE501.
