Buying Guide – What to Look for the best spark plugs for 3.5 EcoBoost?

The ignition coil sends a high-voltage current to the spark plugs. It generates the electric spark that ignites the air-fuel combination in the combustion chamber.

Getting new wires goes hand in hand with changing the spark plugs.

The high voltage current from the ignition coil to the cylinder head is frequently improperly transmitted via a worn spark plug wire.

This instrument can increase the performance of various sorts of vehicles. It includes trucks, motorbikes, and automobiles.

However, we’ve compiled a list of the best spark plugs for 3.5 EcoBoost

f150 ecoboost spark plugs


It would help if you chose a spark plug that is both cost-effective and appropriate for your vehicle and a tool that will improve the overall performance of your vehicle.


Plugs may be made from various materials, each with its advantages and disadvantages. To make a ride more enjoyable, different rides need a variety of tools.

The common types of materials are:


Even though most spark plugs include a copper core, “copper” is often used to describe the most prevalent kind. The electrodes of a conventional spark plug are held together by a nickel-alloy casing bonded to the copper core.

Copper spark plugs are more efficient in high-performance driving because they are quieter and produce less heat. 

Turbocharged engines and engines with more excellent compression ratios generally come as standard equipment.


It is a significantly more brutal metal than nickel alloy, making it more resistant to eroding. These spark plugs are known for their long life spans.

Additionally, platinum spark plugs burn deposits more efficiently and help avoid fouling because of their higher operating temperatures.


At 700° higher than platinum’s melting point, iridium is considered six- and eight-times as hard as platinum. Iridium spark plugs feature incredibly tiny electrodes while maintaining good wear resistance.

Iridium spark plugs can live up to 25% longer than platinum counterparts because of their superior strength.


Our selected instruments are lower in weight and more compact in shape and size than their predecessors. It’s simple to handle and replace them manually as necessary. 

As a result, select the one that is less in weight and will not cause you any difficulties.

The capability of heat:

Because its primary role is to generate a spark when the automobile is started, these tools can withstand extreme temperatures. 

To avoid damage, use a tool with a high tolerance for temperature changes (heat shock).

To compensate for the difficulty of starting a car in cold weather, the spark plugs are designed to function even when temperatures are below freezing.


The space between plugs can be adjusted and fixed on others, but the gap is always critical. It would help if you verified your owner’s handbook whether the retailer advises a fixed-gap plug.

If this isn’t the case, go on to another manufacturer.

Efficacy of Changing Spark Plugs

Spark plug replacement improves your vehicle’s performance and provides several other advantages. These are only a few examples:


Combustion Engine Optimum Operation:

Spark plugs ignite the air-fuel combination in the combustion chamber. Cars with outdated spark plugs might suffer from poor gas mileage and require more running power.

Your vehicle’s performance is enhanced when the spark plugs are working correctly. Investing in a new set guarantees that your engine is in good working order and saves you money in the long term.

It will save you money on fuel.

The National Institute of Automotive Service Excellence has found that a broken or outdated spark plug can reduce your car’s fuel efficiency by 30 percent.

Drivers who have a faulty spark plug might expect to pay more in the long run. Maintenance, gasoline refills, and the like were all on the list.

The engine must use more gasoline to initiate the combustion process if it doesn’t have a vital enough spark. A car’s spark plugs will eventually become less efficient as they wear out.

But adjusting them may avoid this and return your vehicle’s fuel efficiency, economy, and gas mileage to their previous state!

Seamless Performance:

Your car’s performance begins to suffer when your spark plugs wear out over time. An outdated spark plug might cause improper acceleration and engine idling.

Spark plugs used for a long time have a bigger space between the electrodes. Rough idling, sluggish acceleration, and engine misfire result from a disrupted combustion system.

When you replace your spark plugs, all of this goes gone!

Reduced CO2 Emissions:

Pressure builds up in your engine when your spark plugs are worn. New spark plugs should be installed with the proper gap for optimal performance.

According to the Environmental Protection Agency, you may significantly lower your car’s hazardous emissions by changing a worn-out spark plug.

Enhanced Power:

When you replace your old spark plugs with new ones, you’ll notice a noticeable improvement in your car’s performance.

You may not notice a gain in horsepower with a new set of spark plugs, but this is because they restore your engine to its ideal combustion level. To put it another way, your automobile will perform like new, with enhanced acceleration and fuel economy!

Bottom Line

The owner of any vehicle loves it most. They always want to take proper care of their vehicles to provide the best performance. Today we discussed the best spark plugs for 3.5 EcoBoost

Different people have different types of choices. Here we discussed the best ten from the market. Pick the most satisfactory one which you think will be appropriate for you.


Is it true that a car’s spark plug saves fuel?

Yes, these spark plugs are utilized to conserve gasoline while also increasing the engine’s efficiency.

Do radio signals able to pass through the plug or not?

Some spark plugs indeed prevent potentially dangerous radio waves.

How to adjust the spark gap?

Certain equipment will be used to modify the spacing between the spark plugs. The gaper tool may also be used to fine-tune the gap.

How often should I get my spark plugs changed?

If your car needs new spark plugs, you can do so. Consequently, the usefulness of these technologies diminishes with time.

Specific plugs may wear out or corrode over time, while others may need to be replaced more frequently in some Ford F150 engines.


What is the finest tool to use regularly?

There should be just one material utilized to make a plug that impacts the tool’s quality. As a result, you should always utilize a platinum-based spark plug for everyday use.
