These plugs do exactly what they sound like – they create the spark that ignites the fuel in your engine’s cylinders. But the “suppressed” part is key. It includes a resistor built right into the plug. That resistor limits radio frequency interference, or RFI. Think of it like a little gatekeeper for the electrical signal – it allows the necessary spark to jump the gap, but cuts down on stray electrical noise. Basically, it’s a core part of the ignition system. Each cylinder needs a spark plug to get things going. Without a good spark, the engine won’t run right – you’ll get misfires, rough idling, and a loss of power. The suppression aspect protects other sensitive electronics in your car, like the radio, the engine control unit, and even things like anti – lock braking systems. Older cars didn't need these as much, but modern vehicles are packed with computers, so it’s much more important now. Without a working, suppressed spark plug, you’ll notice if it's gone bad. The engine will run poorly, you'll likely get a check engine light, and your fuel economy will drop. The suppression part itself isn’t something you'd feel directly, but it prevents interference that can cause all sorts of electronic gremlins – weird radio static, sensor errors, things like that. Using the right type of plug is crucial. You can find a good selection of suppressed spark plugs at places like Fixparts Online, and they have info to help you find the right one for your car. It’s a small part, but it makes a big difference in how reliably everything runs. Shop with confidence: Suppressed Spark Plug (MPN 0242236560) comes with a 12-month warranty!
