Best spark plugs for Vortec & Buyer's Guide (2018)

Updated November 2018

Vortec engines are an engine designed, developed, and trademarked by General Motors. Vortecs generally found in GMC and Chevrolet brand vehicles. Quite possibly the most famous example of the Vortec engine is the Chevrolet Silverado SS. The Silverado SS comes with the top of the line V8 Vortec Engine with a 5200 rpm and 345 hp rating. The Silverado SS is a popular choice for drivers hauling or driving on challenging terrains. The same engine has also been used in the luxury Cadillac Escalade. While most Escalade owners will take their vehicle off-road, Cadillac has been consistently sold for use by government official and their security details. The Vortec engines provided creates a powerful force in getting away from dangerous security situations.

Vortec engines are unique as they provide high levels of power boost competitors are incapable of producing. For people who push driving to the limit, this option is maybe one of the best available. Another reason why people who prefer Vortecs is their inclusion into some of the best selling vehicles ever. There is a substantial aftermarket with many trained professionals who know how to service this engine properly.

A car goes nowhere when the spark plugs are removed or damaged. You would be surprised by how many people do not understand this fact. A spark plug creates the actual spark that is required for an engine to function. They are also important in getting good performance from an engine. There are many issues that can come from bad spark plugs. The effects can range from acceleration misfires, unsustainable max power, and lower than expected gas mileage efficiency. In a Vortec engine manufactured by General Motors, the model of spark plugs used can be important. Vortecs are powerful engines that necessitate good components.

Electricity is to create the initial spark that ignites a pressurized mixture of fuel and air. The combustion causes a motion that for the piston to work moving up-and-down, creating the motion needed for your engine to achieve its goals of moving your vehicle.

Spark plugs are made to take extremes in heat and pressure. But they don’t last forever, after driving many miles you need to replace them. The number of miles needed before a replacement will be directly dictated by the type of spark plugs used. The material iridium is considered the best material to manufacture spark plugs. Spark plugs made of this last for the longest time period. Many of them can achieve eighty thousand miles of usage before they need to be replaced. Spark plugs made of platinum are considered a mid-level option. They don’t last as long as iridium, but they are nearly as good in almost every other aspect. The lowest levels are copper spark plugs. They don’t last nearly as long as the other two metals. Most copper plugs need to be changed at twenty thousand miles. Copper is the cheapest option so if need a replacement and your budget is tight, then there a few good ones you can choose.

For this article, I am going to assume you are not desperate for cash, and that you want to invest in giving your car the best performance possible. What was considered in making this list include material type, horsepower improvement, and changes to expected fuel efficiency This is specially tailored to the Vortec.

I quickly detailed the purposes they serve. Now you know their importance how to go about and choose the best? I did my own research, and I looked into what would fulfill the needs of most drivers. I considered various factors from cost, materials, engineering, and durability. Taking all of this into consideration, I decided on five spark plugs that I would recommend.

Many people forget why spark plugs even exist. It is just not something most people consider when they buy or decide to upgrade. Consider that big performance differences can be achieved with the proper spark plugs. I am going to list several below several ones that are solid considerations. The vast majority of spark plugs are mechanically similar. An interesting exception to this rule is the spark plugs manufactured by German firm Bosch. As detailed below, they don't have a traditional electrode design. Instead, they have a four-point electrode construction. The rest of the list all have similar engineering.

The metals sourced for the manufacture of a spark plug are important. The highest quality spark plugs are constructed with either iridium or platinum. In the case of cheaper spark plugs, copper is the main material that is used. I cannot recommend this as they just don't last as long. They typically don't last beyond twenty thousand miles of driving. Other materials can sometimes yield four times that driving distance. Iridium is generally considered the best for plugs, with platinum being considered a good mid-level option. Remember that there can be bad iridium plugs and decent copper plugs. After reading this article, do your own research on spark plugs and the manufacturers that make them.

One reason for this is the construction material of iridium that is used. Iridium is considered a gold standard with spark plugs; this feature attracts many buyers.

Iridium is a durable material. Below iridium is the use of platinum. Platinum is used mostly for mid-level products. The bottom level and cheapest are copper spark plugs. Iridium protects the electrode from wear and tear. Reliability is a benefit of this. However, the price is higher than most of the competition. This may be a consideration in your decision in your purchasing decision.

Best spark plugs for Vortec Buying Guide & FAQ

Once you decided to purchase new spark plugs, a few things you should be advised to make an informed decision. Maybe the most important question is what is the brand of vehicle you drive and if it supports a Vortec engine. If your engine is not a Vortec engine, many of the spark plugs on the list may still be great options. But you may need to study the specifications carefully. Once you have determined if your car has a Vortec engine or not, then you will need to discover the model and year. The data can help determine the best for your particular situation. Then check to see if the car has a manual or an automatic transmission. Sometimes a manual transmission is called a “stick” because you need to move a lever to change gears as you drive. Your best spark plug can be influenced by all the above mentioned.

Other considerations when purchasing.

When do you need to purchase new ones?

Here are warning signs that you need replacement spark plugs. A noticeable change is buying gas more frequently. Having bad spark plugs will drop fuel efficiency. Fuel efficiency can decline upwards of thirty percent. Vehicle jerks are an indication of faulty spark plugs installed in your vehicle. This means your engine is surging and this can be a very dangerous situation for everyone on the road. Going on, if you press on the pedal for acceleration, then this slowness could be a sign for new spark plugs. Yet another issue is a rough sounding engine. If the sound is not constant then that could be a big sign that something is wrong with your spark plugs. And finally, a vehicle that has difficulty in starting then, this is a big sign to check the spark plugs. When spark plugs are bad, they really deplete the battery of the vehicle. And the battery can be recharged inside the vehicle if the spark plugs are not sparking thus powering the ignition.
