The OEM in the instance of Nissan would be NGK spark plugs (check prices and fitment). Now, to some extent, the plugs you must choose rely on the model year of your vehicle. The models from 2002 to 2009 come with platinum plugs. These platinum spark plugs, model number PLFR5A-11, are the exact OEM replacement.

A v8 has how many spark plugs?
The total number of spark plugs in your car’s engine depends on two factors: the type of engine and the number of cylinders you have, regardless of whether you drive a Dodge Charger, a Chrysler, a Mercedes AMG, or an Alfa Romeo.
On the other hand, dual spark engines without a distributor and more recent HEMI engines with MDS (Multiple-Displacement Systems) will have two spark plugs per engine cylinder for a total of sixteen spark plugs.
It’s interesting that this only applies to gasoline engines. A glow plug is used in the engine of a diesel vehicle instead. The air-fuel mixture in the diesel engine’s combustion chamber is not ignited by a glow plug. Instead, each cylinder’s superheated compressed air ignites the fuel.
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.
The moment you notice a problem with your ignition coil, call a professional. Should I switch out my ignition coils for spark plugs? should be one of your first inquiries to your mechanic. Have your mechanic check your car to see whether the ignition coils and spark plugs need to be replaced.
How can I tell if I need to replace my spark plugs?
7 Indices That It’s Time to Change Your Spark Plugs
- Starting the automobile is difficult.
- The engine stalls out.
- More frequently, you’re stopping at the gas station.
- The idle of the engine is noisy and harsh.
- Your automobile has trouble picking up speed.
- When driving normally, the engine is rather noisy.

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.
Will OEM spark plugs work?
It’s simple to claim, “I don’t care whether my plugs last another 100k miles,” or “I simply want to save money,” particularly if the vehicle for which you’re purchasing the plugs won’t see another 100k miles of use. However, you won’t have to wait long to pay for a poor set of spark plugs.
Your gasoline expenditures will go up by the same amount if you purchase a subpar set of spark plugs that reduce your engine’s fuel efficiency by only a few percentage points. For instance, if you spend $40 a week on gas and your plugs reduce gas mileage by 2%, your fuel price will increase by around $1 a week (2% of $40 equals 80 cents). Your “cheap” spark plugs will force you to spend an additional $40 on gas in less than a year. A cheap pair of spark plugs will cost a lot of money after five years.
Therefore, OEM plugs are still the best choice even if you’re looking to save money on spark plugs and don’t care about longevity. They’ll guarantee the best efficiency and performance, which will enable you to reduce one of your biggest car expenses (fuel).
Is iridium a superior spark plug material to platinum?
With a 700 higher melting point than platinum, iridium is believed to be six times stronger and eight times tougher than that metal. Spark plugs made of iridium feature incredibly tiny electrodes and good wear characteristics. Iridium spark plugs can live up to 25% longer than comparable platinum spark plugs because of their durability.
Iridium spark plugs include a core electrode made of a thin wire that is intended to carry electricity more effectively and improve firing efficiency.
This valuable metal comes at a cost. Spark plugs made of iridium are often the most expensive, costing between $8 and $15 each.
Are pricey spark plugs worth the cost?
Purchasing high-performance spark plugs is an assured method to save money over time. The first benefit is simply better gas mileage. These premium spark plugs are built to live longer than regular plugs, allowing you to go between tune-ups more frequently while paying less for upkeep. It is simple to understand why consumers pick Pulstar high-performance spark plugs when you pair it with an engine that is more dependable and has a longer lifespan.

Copper
The most basic and cost-effective form of spark plug available is one with a copper core. Due to their improved performance, efficiency, and lifespan, platinum and iridium spark plugs have lately supplanted these as the most popular plug type on the market. Copper spark plugs are simply incompatible with many modern engines, although certain older engines perform better when utilizing copper plugs.
Platinum
Compared to copper plugs, platinum plugs offer better performance and fuel economy, but they cost a lot less than iridium spark plugs. Platinum spark plugs work at a lower temperature than copper spark plugs, much like iridium plugs do. Additionally, they can survive up to twice as long as standard copper plugs.
Double Platinum
Compared to single-plated platinum plugs, double-platinum spark plugs offer even greater performance, efficiency, and durability. Additionally, double-platinum spark plugs are often still less expensive than iridium spark plugs. Simply look for spark plugs that use platinum in both the electrode and cap for an economical upgrade from single platinum.
Iridium
The top spark plugs on the market are made of iridium. Iridium spark plugs outperform double-platinum plugs in terms of performance, lifespan, and efficiency. Iridium spark plugs cost more than copper and platinum alternatives since they are made of a superior material and use cutting-edge technology. Use of iridium spark plugs is ideal for high-performance engines.
Double Iridium
Double-iridium spark plugs resemble double-platinum ones in many ways. Two discs formed of the rare metal are used in double-iridium spark plugs to improve longevity and performance. These spark plugs are made to provide the firepower required for all types of driving conditions, such as intense heat or constant high speeds. In comparison to a typical copper spark plug, double-iridium can offer up to four times the usual life of service.
How much time do spark plugs last?
The majority of manufacturers advise replacing spark plugs every 30,000 miles (or more, for extended life spark plugs). By doing this, decay, carbon fouling, or issues with worn spark plug tips are reduced. Additionally, it aids in avoiding problems with the combustion chamber or cylinder.
However, the brand, model, and kind of spark plugs you use will also affect how often they need to be replaced.
Here are some details on the lifespans of several plug types:
- Although it is claimed that the double platinum spark plug will last up to 100,000 miles, actual mileage may vary from brand to brand.
- The typical lifespan of a copper spark plug is between 10,000 and 20,000 miles.
- Long-lasting or extended-life spark plugs can go 100,000 miles.
- Platinum or expensive iridium spark plugs can last 60,000 kilometers.
- Premium iridium spark plugs have a 100,000 mile lifespan (although an extended life iridium spark plug may last up to 120,000 miles).
- Silver plugs, which are utilized in older automobiles, have a 20,000-mile lifespan.
