NGK Laser Iridium Spark Plug Box of 4 (SILMAR9A9S)

When it's time to tune up your 2009-2020 Honda CRF450R, getting the right spark plugs makes a big difference. These NGK Laser Iridium plugs are built to be a direct replacement for your OE plugs, meaning they're designed to work perfectly with your bike's ignition system right out of the box.

The center electrode uses an iridium alloy, which is much harder than platinum and can handle the high temperatures and pressures inside your engine for a long time. This helps ensure a consistent spark, which is important for smooth running and reliable starts. The pure alumina ceramic insulator helps manage heat, and the trivalent metal plating on the plug body helps prevent corrosion and makes them easier to remove later on. You'll want to order four of these to get a full set for your CRF450R.
