It might be time for you to replace your spark plugs!
The spark plugs in your car are essential if you want to reach your next destination. Your car may run a while without oil or water; however, your spark plugs activate your engine, so you need them to be in perfect condition at all times. But what spark plug should you be using? We highly recommend you read your car user manual because there are four major types of spark plugs.

Before forking over your hard-earned cash for a new set of spark plugs, you need to figure out which type you need. There are 4 different types of spark plugs and they are listed below with a brief explanation.
Austin explains these different spark plug types well in this video
Spark plugs are designed to produce a small spark of electricity that leaps across a short distance between the center electrode and ground electrode. Once fuel is injected inside the combustion chamber, it is the spark plug’s job to ignite the high-compression mixture of fuel and air. This combustion process enables the pistons to move up and down to propel your vehicle.
Spark plugs are the focal point of the combustion process.
Spark plugs also extract heat from the combustion chamber and transfers it to the vehicle’s cooling system. These high temperatures mean your spark plugs need to be manufactured from the highest quality materials, otherwise they won’t stand the heat and could malfunction prematurely.
Their presence is essential and their quality is vital. Low quality spark plugs may quickly wear out; this can leave you in the lurch without warning. High-quality spark plugs last thousands of miles so you don’t have to change them frequently. In some modern cars, spark plugs are quite expensive so you need to make sure the correct ones are installed to last you a long time.
The brand is not the most important part of the equation. While it is normal for engines or car brands to prefer a specific type of spark plug from an OEM manufacturer, the most important thing to consider is the serial number of the spark plug.
Check the owner’s manual of your vehicle to determine the serial number of the OEM spark plug. It is extremely important to follow the recommended spark plugs indicated in the owner’s manual. Using the wrong spark plugs is simply a waste of time and money. It can also damage your motor.
For example, if your vehicle should be fitted with NGK LZFR5B1-11 spark plugs, make sure to choose the exact same serial number. The LZ code means the spark plugs are NGK Lazer Iridium and are one of the most expensive spark plugs you can buy today.
When you’re looking for spark plugs you need to keep the following guidelines in mind:
Size
Vehicles differ in size and engine design. Make sure you purchase spark plugs that will fit inside your vehicle’s cylinder head. Check the owner’s manual to be sure.
Quality
If you have a newer or modern vehicle, you will most likely need Platinum or Iridium plugs. Make sure you choose a brand which uses quality materials during manufacturing. This determines how quick the spark plugs respond and how long they’ll serve you well.
Functionality
Do you run a super-charger and need the best spark plugs for horsepower? Or do you have a Honda Accord and just want the best spark plugs for gas mileage?
High quality spark plugs will burn off residue from the combustion process so you don’t have to clean them constantly. You can change your spark plugs yourself, but otherwise you can get it done during regular vehicle servicing.
Iridium plugs can last up to 125,000 miles and Platinum is close behind at 100,000 miles. But if you’re running a turbocharger or high-performance engine the combustion is often increased which means more wear on your plugs.
Your car manual will give you the best estimate. However, if any of the following occurs you may need to change them sooner:
1. Idling troubles
The vehicle should idle smoothly and consistently. If the idling is jittery or makes your car vibrate excessively, get your spark plugs checked immediately.
2. Hard starting
Is your vehicle hard to start, particularly in cold weather? You better get your spark plugs checked. Worn plugs won’t be able to start your car. Repeated and prolonged cranking of the motor can also drain the battery.
3. Engine misfiring
Your car may run, but it might experience occasional misfires during your driving. With worn spark plugs, all cylinders can’t function properly. You also run a risk of increased emissions.
4. Surging
If your vehicle starts and stops intermittently, your spark plugs may be faulty. Your vehicle will jerk forward and slow down without warning, which is dangerous and frustrating.
5. Fuel consumption problems
As your spark plugs deteriorate over time, their efficiency influences fuel economy. It can lower efficiency up to 30%, but changing your spark plugs will quickly fix the problem.
6. Can’t accelerate
If your vehicle drags more than usual when you step on the accelerator, your spark plugs might be at fault.
If any or all of those symptoms are present, you should have your spark plugs checked immediately. You may need to clean or replace the spark plugs when necessary. If you still refuse to pay attention to the danger signs of a dad or faulty spark plug, you run the risk of stalling in the middle of the road and eventually damaging the engine in the process.
So there you have it. The best spark plugs that you can buy for your car or truck. There are a ton of options out there and we hope this buying guide has helped you! If you have any questions, leave a comment below, or contact us!
