This little guy basically takes electrical noise created by the spark plugs and cuts it down. Think of it as a filter, smoothing out the electrical signal. It does this by resisting radio frequency interference – that’s the noise. It’s a resistor designed to work with your ignition system. It slides right onto your spark plug wire, right where it connects to the spark plug itself. It sits between the ignition coil and the plug. It’s part of the high – voltage system that gets the spark going inside your engine. It's designed to work with the resistance wire in your spark plug wires. That electrical noise I mentioned? It can really mess with other sensitive electronics in your vehicle. Things like your radio, your engine control unit, even your anti – lock brakes can get confused by that interference. The suppressor acts like a shield, preventing that noise from causing problems. You’ll notice if yours are failing if you get static on the radio, or if you start having weird electrical issues that don’t seem to have an obvious cause. They don’t always cause a check engine light, so it can be a sneaky problem. You can find these pretty easily online, actually – Fixparts Online has a good selection, just so you know. They’re a relatively cheap part to replace, and it can save you from having to deal with bigger, more expensive issues down the road. Your peace of mind matters: Enjoy a 12-month warranty on Spark Plug Suppressor (MPN 0356351053)!
