NGK Laser Iridium Spark Plug Box of 4 (SILFR5A11)

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a prime example of that. If you're looking to replace the spark plugs in your 2010-2013 Suzuki SX4, these are built to meet or exceed the original equipment specifications. They're designed to provide a consistent, strong spark, which is crucial for smooth engine operation and efficient fuel combustion.

What sets these plugs apart is the iridium center electrode, which is significantly harder and more durable than platinum. This means they're built to last longer and maintain their performance over time. You'll also find a platinum pad on the ground electrode, which helps ensure even wear, especially in modern distributorless ignition systems. The pure alumina ceramic insulator helps with heat transfer, keeping the plug from overheating, and the copper core further aids in heat removal. Plus, the trivalent metal plating on the threads helps prevent corrosion and makes them easier to install and remove without seizing.

This set includes four spark plugs, which is exactly what you'll need for your four-cylinder SX4. They're a direct replacement for your original plugs, so installation should be straightforward, but always refer to your vehicle's service manual for the correct torque specifications.
