NGK Laser Iridium Spark Plug DFE Box of 4 (DF5B-8A)

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 2013-2018 Lexus ES300h, these are built to the original equipment standards. They combine a fine wire center electrode made of iridium, which is six times harder than platinum, with a platinum pad on the ground electrode. This design helps ensure a consistent and stable spark, which is important for both performance and how long the plugs last.

The pure alumina silicate ceramic insulator is strong and helps transfer heat away from the plug, preventing it from overheating. You'll also find trivalent metal plating on the threads, which helps prevent corrosion and makes them easier to install without seizing. The pure copper core inside also plays a role in heat removal, contributing to reliable starts. These plugs are designed for distributorless ignition systems, promoting even wear and improved spark performance over time.

This set comes with four spark plugs, which is what you'll need for your ES300h. They are a direct replacement for your original equipment plugs, meaning they should fit right in without any modifications.
