While you should buy spark plugs in matching sets for your vehicle, not all spark plugs are universal. Spark plugs come in different sizes with different gaps and are manufactured using a variety of metals.
Spark plugs are essential for your vehicle and it’s imperative that you make sure you’ve got them in your motor when they need replacing. The last thing you need is to be caught short and stranded with a failed vehicle
Finding the ones that you need can be difficult.
Spark plugs should be replaced every 30,000 miles. The factors that should prompt you to check whether or not your spark plugs are in bad condition are: misfiring, rough idling, loss of performance, spark plug fouling(this can also be brought on by oil getting on the electrode thus preventing the spark plug from working properly)
Types of Spark Plugs
Spark plugs can be split into two categories: standard and performance.
Performance spark plugs use superior-quality materials such as Iridium and Platinum, with better electrodes and more durable metal tabs. These stronger parts make it possible to run higher performance engines for longer distances. These performance spark plugs have a longer lasting electrode, providing a stable arc and improving efficiency. Additionally, spark plug cleaning is unnecessary with performance plugs.
Most spark plugs use expensive iridium electrodes, but standard plugs feature all-nickel metallic construction, which has 50% more heat resistance to extend the life of the plug. They are ideal for older or high-mileage vehicles, because they are better able to withstand the excessive temperatures caused by detonation. They are priced 40 to 50% less than other spark plugs, so they are a great value too!
Replacing Your Spark Plugs
Spark plugs can be a mystery to even the most seasoned mechanic. The varying voltages and materials mean it’s important to buy the right ones for your engine, and even the right heat range if your engine gets particularly hot. With so many spark plug manufacturers available today, it’s vital to have a system that keeps track of all these different specs. You don’t want to buy the wrong spark plugs and hurt your vehicle.
