When To Change Spark Plugs Of Nissan Altima?
You will face unwanted situations with the car when spark plugs go bad. Nissan recommends going to servicing your vehicle after crossing 100,000 miles. Nissan Altima spark plug replacement schedule is a 105,000-mile mark and beyond. It still depends on how often you are using the car.
Dirty and fouled spark plugs can reduce the fuel economy of the vehicle. If you feel that you are going to gas stations too often, probably it’s time to change the plug. Also, when a spark plug gets fouled or dirty, it doesn’t spark effectively, resulting in sluggish acceleration.
The combustion process is hampered due to the dirty plugs. It can cause the engine to misfire instead of running smoothly. You may also hear a rough sound coming from the engine or feel the car’s vibration because of the faulty plug.
If you face any situation like the above, you need to change the existing spark plug with a new one. Even if one of the spark plugs is found dirty or faulty, you should replace all in sets. If you continue with fouled plug anyway, the problems will get worst eventually.

Key Features For Nissan Altima Spark Plugs
Many people simply ignore this thing where you should be most careful. Buying a spark plug that doesn’t fit your car or against your owner’s manual can both waste your money and time. Make sure you go through these must-have key features to consider before you buy spark plugs for your favorite ride.
Spark Plug Types Explained
Spark plugs are made of different metals. Based on the metal used, spark caps are classified into different types. Each type of spark plug has specific advantages to use.
For example, copper spark plugs are the least expensive but last less than other types of plugs. They require more voltage and are suitable for earlier vehicles especially before high-energy distributor ignition system engines became popular.
Platinum spark plugs are more robust than copper caps with a long lifespan. They require less voltage to operate and reduce misfires during the startup of the engine.
Iridium spark plugs are the most expensive but serve you the best. They usually run more than other types of spark caps.
But we recommend you stick with the type of spark plugs that are instructed in the owner’s manual. After all, your Nissan Altima engine is built considering the nature of the plugs. However, if you want to try new plugs you should go for different types of spark plugs in detail.
First thing first. You need to check back the material your Altima model fits before purchasing. Copper is ideal for old-fashioned models that feature low-voltage distributor-based ignition. Platinum and Iridium are commonly better for modern vehicles. Platinum plugs provide fuel efficiency, performance, and longevity. Iridium also serves excellent at a higher cost. But, before you go for any of them, you should follow what the car manufacturer recommends.
Spark plug size
The diameter of the threads determines the size of the spark plug. If you install the wrong-sized plug, you can cause anything from the cap not being able to be torqued down to damage the cylinder head by either cross-threading or trying to jam the plug in a place where it won’t fit.
Spark plug reach
The reach of the spark plug is the length of the threads. Reach also tells us how far a spark plug goes in the cylinder head. You will see a darker portion of the thread before it gets down to the electrode that goes into the cylinder head. If your plug doesn’t have a sufficient amount of reach, it won’t go far into the cylinder to produce proper combustion. On the other hand, if the reach is too long, it can cause pre-ignition, piston, or valve hitting the spark plug.
The heat range is determined from the tip of the insulator to the sealing ring. The range is listed on the side of the plug. A longer distance from the sealing ring to the insulator’s tip is called a ‘hotter’ plug. When you install a hot plug in your car, pre-ignition may occur in the cylinder. The cap is a better insulator. Installing a colder plug file, the plug out really fast due to deposits building up on the socket. A cold spark plug can conduct more heat out of the tip to lower its temperature.
Spark plug gap
A spark plug is designed for various models of vehicles. Different vehicles maintain a different spark plug gap. For Nissan vehicle, it is 0.044″ or 1.1 mm. So, before installing a spark plug, use a gap gauge to measure the socket gap. This will fit your vehicle and produce proper combustion.
A Note: Don’t use a screwdriver/ pliers to bend the gap open that may damage the plug.
The spark plug is the primary component required to power the engine. If you don’t choose the best caps for the engine, don’t expect much from the car. So, spend some time to find the best spark plugs for Nissan Altima that you drive daily. The other problems will automatically be solved.
