Premium spark plugs not only meet original equipment specifications, many times they exceed them.
Don’t be lured by low prices
Don’t grab the cheapest spark plug at the auto supply store: remember, you usually get what you pay for. A lower price spark plug may not have the features and performance you are looking for.
Consequences of using cheap or inferior spark plugs
Cheaper spark plugs are often lesser quality, using inferior materials that over time lose their ability to provide the spark for the combustion process. Lower grade spark plugs may not be built to original equipment specifications which can lead to many issues including decreased fuel mileage, poor acceleration, engine misfires and hard starts.
If you select lower grade spark plugs, you could be missing out on technological advancements that lead to longer life and improved performance. Lesser quality spark plugs can show signs of fouling sooner than premium plugs, meaning that you’ll have to replace them more often.
How to select a quality spark plug for your car
There are three main types of spark plugs for passenger cars: basic copper spark plugs, platinum spark plugs and iridium spark plugs. Each spark plug type offers distinct advantages and disadvantages.
The basic copper spark plug is the most common and cheapest plug available. However, due to the soft nickel-alloy outer material, copper spark plugs have a decreased lifespan of about 20,000 miles.
Platinum spark plugs boast longevity and resistance to fouling. Since platinum is harder, it holds its sharp edge much longer than a conventional spark plug, up to 100,000 miles. Platinum spark plugs come in two varieties - single and double platinum.
Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs. Iridium spark plugs also feature excellent wear characteristics. But there is a price for this precious metal. Iridium spark plugs are typically the most expensive ranging from $8 to $15 each.
Do your research to learn which spark plug is right for you. If you aren’t sure where to begin, consulting your owner’s manual is a good starting point. There you’ll learn the recommended spark plug for your vehicle. You can also consult us for guidance on selecting the best spark plug for your car.
