Without a spark, a fire cannot be started. The spark plug, a tiny but incredibly important part that enables internal combustion, ignites the fire in the majority of cars and trucks. Your engine creates energy by conducting thousands of little explosions every minute, unless you drive a diesel or a battery-powered vehicle. Maintaining the performance of your engine will be greatly aided by using the right spark plug for the job.
Although they all do the same difficult task, not every engine need a spark plug for it. Modern gasoline direct-injection engines are more efficient than ever, and the design and composition of spark plug electrodes have changed to keep up with engine needs. Spark plugs with iridium, platinum, or other equivalent noble metal coating and wire tip electrodes that have been laser welded are made to maximize performance. Modern spark plugs are frequently durable enough to last 100,000 miles or more before they require maintenance, in contrast to the previous century, when they frequently needed to be cleaned or changed every 15,000 miles or less. This is made possible by vastly improved modern computer-controlled ignition systems.
The engine’s design has a significant impact on the “optimal spark plug,” but cost and performance are also crucial considerations. Older engines with less sophisticated fuel management are well-suited for standard (and frequently less expensive) spark plugs composed of less exotic metals like nickel, but it doesn’t work the other way around.
Our compilation of the best spark plugs outlines the top possibilities, but it’s up to you to identify the correct component number for the year, make, and model of your car. Pay close attention to the engine specifications as some cars come with a variety of engines. Additionally, to help you make sure you’re obtaining the right plug for your car, the majority of manufacturers include application charts and cross-reference documents on their websites.

List of Top 5 Best Spark Plugs in 2022 on Amazon.com
#1 AC Delco original equipment
The greatest spark plugs for any engine are the ones that were originally installed, and these AC Delcos were one of the most well-known and productive engines of all time. The 100 millionth small-block Chevrolet V8 engine was produced by General Motors in 2011, but the company didn’t stop there. It makes perfect sense to use original equipment replacement components, especially for a vital and affordable component like a spark plug.
What We Like:
- Original equipment requirements
- Performance and factory fit
- superior robustness to aftermarket
What We Don’t Like:
- confused about part numbers from the past, looking for the proper fit
- Pricey compared to aftermarket alternatives
- Be on the lookout for fakes and imitations.
#2 TT Denso Iridium
Original equipment spark plugs don’t necessarily require a trip to the dealer, and there are other options besides AC Delco (see above). All of the aftermarket parts that Denso provides to automakers across the world meet or exceed the original equipment standards. Twin tip electrode technology, originally developed by Denso for high-end luxury and exotic cars, is now available for economy runabouts like a Ford Fiesta ST with these Iridium TT spark plugs. The Iridium TTs are made for a correspondingly wide range of vehicles, so finding a part that fits is simple.
What We Like:
- reaches or surpasses OEM quality
- sophisticated twin tip technology
- enhanced efficiency and performance
What We Don’t Like:
- availability issues in some locations
- a higher cost than a non-twin tip
- Market for parts is flooded with counterfeiters
#3 Diamondfire E3
The Diamondfire ring electrode, a patented invention of the E3 engineering team, combines the benefits of conventional j-shaped electrodes and surface electrodes for better combustion. For anything from lawn and garden tools to passenger cars, E3 supplies spark plugs. So test one in the old lawnmower or install a set in a Chevy pickup and make your decision.
What We Like:
- Ground electrode with a patent for better combustion
- a variety of applications and part numbers
- unbiased testing and race-proven
What We Don’t Like:
- Performance entails a higher price.
- Some automobiles do not support this.
- Your results may vary.
#4 Spark Plugs NGK
NGK is a great option for standard electrode and noble metal wire tipped spark plugs due to its consistently high quality, extensive applications catalog, and time-proven performance. These common copper core plugs from NGK, an OEM provider, were standard equipment on the majority of Japanese cars, SUVs, and motorbikes from the 1960s through the 1980s. We have also used them successfully for many years in older vehicles from other nations. Look around for the other common NGK plugs; they are all of great quality if unit 7634 does not match your vehicle.
What We Like:
- OEM quality that is consistent and factory-fit
- Performance that is reliable and predictable
- Outstanding value and toughness
What We Don’t Like:
- not as long-lasting as platinum or iridium
- Not suggested for more recent engines
- standard non-wire tip electrode
#5 Winner Copper Plus
Champion spark plugs provide reliable performance for both daily drivers and the fastest automobiles in the world. Additionally, lawnmowers and gardening tools require maintenance, and this popular Champion Copper Plus spark plug keeps tiny engines operating at their peak efficiency. Standard spark plugs are a favorite for springtime tune-ups because they’re inexpensive enough to buy a few more for upcoming seasons.
What We Like:
- premium traditional spark plug
- For many tiny engines, the part number
- affordable price and reliable performance
What We Don’t Like:
- Not all tiny engines are appropriate
- less resilient than platinum or iridium
- Popular enough to warrant imitation
