Your factory spark plugs are an essential part of your vehicle's ignition process. They create the initial flash of electricity that ignites the air-and-fuel mixture inside the engine.
How Spark Plugs Work
Spark plugs do that by firing an arc of electricity across a gap between their two leads. The gap is precisely calibrated to deliver the ideal sparking required to kindle the mist in the engine cylinder. Once that happens, the pistons start pumping, the crankshaft rotates, and you have the the power you need to head off for the day. Unfortunately, even the best spark plugs can begin to lag in performance. That affects your ability to start and drive your Porsche.
How to Spot Failing Spark Plugs
It may be that the leads have grown too far apart to produce an effective spark, or perhaps the spark plugs have corroded. You'll want to check the condition of your spark plugs if you detect any of these symptoms:
- Engine misfires
- Uneven engine idle
- Problems starting your vehicle
- The "Check Engine" light comes on
Genuine OEM Spark Plugs Perform Best
If you're not experiencing any of these problems, look for the recommended maintenance schedule in your owner's manual. You don't want to risk using your spark plugs past their rated mileage, since they'll start to fail at that point. When you do need to replace yours, get the right ones for your vehicle. Those are always genuine Porsche, since they're the only ones guaranteed to be compatible. Buy yours now and we'll ship your order straight to your door!
