5 Best Spark Plugs for Gas Mileage and Performance

Last Updated on November 19, 2019

The spark plug is a very important part of any vehicle. It creates the electric current needed to ignite the mixture of air and gasoline that has been compressed in the combustion chamber.

There are a few different types of spark plugs on the market; some good, others not so good. If you have high-quality spark plugs in your vehicle, then you’ll allow your vehicle to get the best gas mileage and performance out of it that you can.

A spark plug that fails to generate a powerful enough electric current will either result in your engine having a weaker performance or no performance at all. Your gas mileage will also suffer from this too because the combustion chamber will require more gasoline to sustain the power needs of the engine.

Don’t let yourself fall into this trap. Take it upon yourself to purchase the best spark plugs possible for your vehicle.

Top 5 Best Spark Plugs

There are many variations of spark plugs available on the market. If you were to go to your local auto repair shop and ask for a new spark plug, they probably wouldn’t tell you what kind of spark plug they’re putting into your vehicle.

So, if you were to educate yourself on the best spark plugs around, then you’d know what to spark plug to request for your vehicle. Better yet, purchase them beforehand (you’ll save some money) and simply have the repair shop install them for you if you don’t feel comfortable doing the job yourself.

Without further ado, here are five of the best spark plugs for the money:

#1 – NGK G-Power Spark Plugs

NGK G-Power platinum alloy spark plugs are arguably the best spark plugs for the money. They offer excellent performance with greater fuel efficiency to save you money in the long run. The center electrode is a fine iridium wire while the ground electrode is made of nickel alloy. They are made to last 30,000 to 50,000 miles.

#2 – NGK Iridium IX Spark Plugs

The NGK Iridium IX plugs are high quality iridium spark plugs made for the auto enthusiast who demands better performance. They are designed to operate over a much wider heat range than the competition. They come pre-gapped but check your owner’s manual to confirm correct gap. Expect a 40,000 to 50,000 mile lifespan.

#3 – Bosch Double Platinum Spark Plugs

They may be slightly more expensive than others, but with Bosch Double Platinum plugs, you certainly get what you pay for. There’s good reason why Bosch is the OEM spark plug used by many car manufacturers. Because of the ultra fine wire design, expect better ignitability, performance, and fuel economy. Their 5-year satisfaction guarantee also says something about their long service life.

#4 – Denso Platinum TT Spark Plugs

Denso is another well respected brand when it comes to high quality spark plugs. The Denso Platinum TT plugs offer twin-tip technology with a platinum center electrode and titanium enhanced ground electrode. You’ll likely get faster starts, better fuel economy, and quicker acceleration over the lesser plugs you currently have.

#5 – Motorcraft Platinum Spark Plugs

If you have a Ford, it’s hard to beat genuine Motorcraft spark plugs. The platinum electrode plugs come pre-gapped and are the direct OEM replacement that came with your Ford car or truck. Get quieter idling, faster startup, better gas mileage, and better overall performance. Your vehicle will feel like the day you bought it.

Cost to Replace Spark Plugs (DIY vs Professional)

It is fairly simple for almost any car owner to replace bad spark plugs with new ones. Changing spark plugs yourself should only take a few minutes to do correctly. Since there is one spark plug per cylinder, a 4-cylinder car should theoretically take half the time of replacing spark plugs on an 8-cylinder.

By doing it yourself, you can save anywhere from $60 to $100 versus going to a professional mechanic. As you can see from the list above, the cost of the spark plug pieces is very inexpensive.

You could be looking at no more than $20 to $40 if you do it yourself versus $80 to $140 if you let a repair shop or dealership do the job. You’ll likely be paying at least double the parts price since spark plugs have a huge markup.
