These leads – sometimes people still call them spark plug wires – basically deliver the high – voltage electricity from the ignition coil to the spark plugs. Think of it like a really important electrical connection. The kit includes all the leads needed for your engine, and often new boots that go over the spark plugs and the coil terminals. Those boots are important, they seal out moisture and keep the connection solid. They’re a critical part of the ignition system. The ignition system, as a whole, is what makes your engine actually go. The leads specifically take that high voltage pulse and get it where it needs to be, at the right time, so the spark plug can ignite the air – fuel mixture inside the engine cylinder. Without that spark, nothing happens. It’s a pretty direct line from these leads to getting the car moving. Well, over time, the insulation on these leads breaks down from heat and age. They can start to leak that high voltage electricity – you might even see a little arcing on a dark night. That leaked electricity doesn't get to the spark plug, so you'll start to notice misfires, rough idling, a loss of power, and your gas mileage will probably drop. They essentially act like a shield, preventing that high voltage from going anywhere but to the spark plug. If they’re failing, you’ll notice if the engine is stumbling, especially when accelerating. A bad lead can even damage the ignition coil. You can find kits like these at places like Fixparts Online, and it's usually a pretty straightforward job to replace them – although a little fiddly sometimes! They’re a relatively inexpensive part that can make a big difference in how your engine runs. Confidence in every purchase: Ignition Lead Kit (MPN ADM51622) is covered by a 12-month warranty!
