This little piece essentially makes the electrical connection between the ignition coil and the spark plug. It's how the high – voltage pulse actually gets to the plug so it can create the spark that fires the engine. It’s a simple job, but critical. It has to deliver that spark reliably, every time. Some connectors also ground the system, providing a return path for the electricity. Think of it like a link in a chain. Your ignition system is all about getting that spark at exactly the right moment. The connector is one of the pieces that has to work perfectly for that to happen. It’s part of the high – voltage side of things, so it's constantly being stressed. It sits right where things get hot and vibrate, so it takes a beating. If this connector fails, you’re going to have misfires. You’ll notice if the engine starts running rough, maybe hesitates when you accelerate, or even won’t start at all. It acts like a shield, protecting the connection from the elements and corrosion. When it goes bad, that protection is gone and the electrical connection becomes unreliable. You might see a check engine light come on, too. These aren't super expensive parts, and a failing one can really cause some serious driveability issues. We carry a lot of these at Fixparts Online, and replacing it is usually a pretty straightforward fix. Guaranteed quality: Connector (MPN 0356250029) includes a 12-month warranty!
