Should I switch to spark plugs instead of ignition coils?

Spark plugs and ignition coils work in tandem. The other cannot work correctly if either one fails. So, should spark plugs be used in place of coil packs? It varies.

The spark plugs are the part that needs to be changed the most frequently along with the ignition coils. Coils can be overworked by worn spark plugs, and the effort needed to replace both parts is frequently overlapped. It is advisable to repair both parts at once if your worn-out spark plugs caused your ignition coils to fail.

However, unless there are indications that they are malfunctioning, replacing your ignition coils at the same time that you replace your spark plugs as part of routine maintenance is not necessary.

It is advised to replace the wires in ignition/spark plug systems if they look to be brittle, worn, or broken. If moisture (such as an oil leak) has harmed the ignition coils, the moisture source should also be fixed in order to prevent the problem from reappearing too soon.

  • To the new plug, reattach the plug wire. Twist the boot until it is securely fastened to the top of the plug.
  • Maintain cleanliness in the vicinity of the spark plug port. To ensure adequate contact between the new plug and the seat, wipe the seat with a clean rag.

Why do spark plugs cost so much?

The majority of automobile manufacturers ceased making the plugs accessible because replacing them is no longer an annual maintenance task. In order to reach the plugs nowadays, the intake manifold may need to be removed along with other complicated tasks.

When you were younger—or older if you were your parents—

A tuneup was a yearly maintenance procedure for your vehicle. For $19.95, the mechanic tested or changed the rest of the ignition system in addition to replacing the spark plugs, points, and condenser (really old). Additionally, the spark plugs were rather simple to access because it was such a frequent event. Most of the time, all it took was opening the hood to reach them. In instance, one automaker received a lot of negative press when they created a vehicle that needed the engine jacked up in order to access one of the spark plugs.

However, the tune-up has evolved during the previous 20 years or so. Most cars’ spark plugs should last for 50,000 miles or longer before they need to be replaced. And the ease of access to those spark plugs is no longer a priority for the producers. Before you can access the spark plugs on many cars, you first need to remove the intake manifold and carefully detach and remove each cylinder’s unique ignition coil. It’s a significant job that takes a lot of effort and knowledge.

The good news is that you shouldn’t have to worry about it too frequently; in fact, it won’t come up at all for many people. The better news is that your local Cottman Transmission and Total Car Care store is the only place you need to go if you need to replace the spark plugs in your car.

How can I tell if my spark plugs need to be replaced?

Sometimes just swapping out one of the smallest parts—the spark plugs—can greatly enhance your car’s performance. Spark plugs, which are little but formidable, are very important to your car. To ensure your vehicle operates at its peak performance, stay on the lookout for the warning indications of faulty spark plugs and replace them frequently.

What Do Spark Plugs Do?

Small electrical devices called spark plugs start the combustion process in your car’s engine. They supply the necessary “spark” for the air-fuel mixture to ignite in the combustion chambers of the engine cylinders, producing power for the engine. Your car starts, maintains power, and operates smoothly in this manner.

How Long Do Spark Plugs Last?

The performance of your engine may be affected by the state of your spark plugs. Fortunately, despite their extensive usage (they “ignite” thousands of times each minute! ), spark plugs don’t need to be replaced very frequently.

Most manufacturers advise replacing spark plugs every 30,000 miles, however depending on the kind of spark plugs your automobile has, you could be able to go up to 100,000 miles. For instance, a spark plug made of copper won’t survive as long as one made of a more durable substance, such as platinum or iridium.

Engine Misfires

One or more of your spark plugs may not be burning properly if your engine is misfiring, which is a clear symptom. A misfire may feel like a sudden loss of power or intense shaking, sound like spitting, or both. A broken catalytic converter, poor vehicle performance, poor fuel efficiency, increased exhaust emissions, and frequent misfiring are all possible consequences.

Poor Gas Mileage

Your engine’s spark plugs burn fuel effectively when they are functioning properly. Deteriorating spark plugs may be to blame if you realize you are using less gas per tank. The distance between the plug electrodes can increase or decrease as spark plugs get older. Because of this, the spark plugs either don’t fire at all or fire inconsistently, wasting fuel and raising pollutants.

Trouble Starting

Especially in cold weather, it might be challenging to deliver the spark required to start your car’s engine when the spark plugs are dirty, broken, or worn out. As a result, the car can start jerkily or take a long time to crank. If this keeps happening over time, your starter and engine may be harmed, and your battery may be discharged.

Slow Acceleration

Your spark plugs may be the reason your car doesn’t respond as quickly when you push the gas pedal as it usually does. But there are other possible causes for this, like clogged fuel injectors, broken oxygen sensors, or a defective fuel pump. Therefore, before spending money on new spark plugs, be sure to get your car diagnosed by a skilled mechanic.

How can spark plugs be checked without removing them?

  • affix an ignition wire tester to the spark plug. The tester’s other end is connected to the spark plug that is currently installed in your engine.
  • Activate the ignition.
  • Watch the transparent sides of the tester while you start the engine or, if it won’t, simply flip it over. You can be certain that there isn’t a spark at the crucial spark plug tip if there isn’t a visible spark or glow. Does this indicate a defective plug? No, not always. Yes, a faulty spark plug is a possibility, but an ignition system malfunction could also be to blame for a lack of spark.
