NGK Lexus GS300 2005-1998 Direct Ignition Coil Boot

If you're working on your 1998-2005 Lexus GS300, the NGK Direct Ignition Coil Boot is a smart replacement part. This boot connects the ignition coil directly to the spark plug, and it's crucial for a strong spark. Over time, these boots can crack or degrade, leading to misfires or ignition problems. NGK builds these boots to meet the same standards as the original parts your car came with, ensuring a proper fit and reliable performance.

NGK uses quality silicone for these boots, which helps them stand up to engine heat and resist damage. They also include any necessary internal springs and resistors to ensure your ignition system suppresses radio interference, protecting your car's electronics. Replacing these boots when you change your spark plugs is a good practice to avoid future ignition issues like flashover, where the spark jumps to the wrong place instead of going down the plug. This part is designed to fit right and function just like the original.
