NGK Infiniti FX45 2008-2003 Direct Ignition Coil Boot

When you're changing out spark plugs on your Infiniti FX45, Nissan Altima, or any of the many other vehicles this part fits, it's a smart move to replace the ignition coil boots at the same time. This NGK Coil on Plug (COP) boot is built to the same specs as the original part your vehicle came with. It's a crucial link, making sure the spark from the ignition coil gets to the spark plug cleanly and efficiently.

NGK uses quality silicone for these boots, which helps them stand up to the heat and vibration under the hood. They also include any necessary internal springs and resistors to help suppress radio frequency interference (RFI) and electromagnetic interference (EMI). This means your vehicle's electronics are protected from ignition noise, and you get a solid spark every time. Replacing these boots along with your spark plugs helps prevent issues like flashover, ensuring your engine runs smoothly.
