NGK Infiniti Q45 2001-1997 Direct Ignition Coil Boot

When you're replacing the spark plugs on your 1997-2001 Infiniti Q45, it's a good time to also swap out the ignition coil boots. These boots are the crucial link that connects the ignition coil directly to the spark plug, making sure that spark gets where it needs to go to fire up your engine. If these boots get old, cracked, or worn out, you can end up with ignition problems like flashover, which means a weak or missed spark, leading to rough running or even misfires.

NGK makes these boots to fit just like the original ones from the factory, using good silicone material that holds up well over time. They also include any necessary internal springs and ferrite resistors, which are important for making sure your ignition system works right and doesn't cause any electronic interference (RFI noise) that could mess with your car's other electronics. By replacing them when you do your plugs, you're ensuring a strong, reliable spark and helping to prevent future ignition issues.
