What are the highest quality spark plugs?
When it comes to maintaining your vehicle's performance and efficiency, choosing the right spark plugs is crucial. Spark plugs play a vital role in igniting the air-fuel mixture in your engine, ensuring smooth operation and optimal fuel economy. With so many options on the market, it can be challenging to determine which spark plugs are the best for your car. In this article, we’ll explore the highest quality spark plugs available and what makes them stand out.
Why Spark Plug Quality Matters
Spark plugs are small but mighty components of your vehicle's engine. High-quality spark plugs can improve engine performance, fuel efficiency, and even reduce emissions. On the other hand, low-quality or worn-out spark plugs can lead to misfires, reduced power, and increased fuel consumption. Investing in the right spark plugs ensures your car runs smoothly and reliably.

Frequently Asked Questions
What is the number 1 spark plug?
The number one spark plug is always found in the number one cylinder of the engine (or the number one *rotor* in a Wankel). Look at the end of the engine closest to the accessory drive. From there, locating cylinder one is easy for any inline configuration.
Do higher quality spark plugs make a difference?
Upgraded spark plugs possess a finer centre electrode, allowing for a sharper, more concentrated spark. This promotes better combustion, improving throttle response, increased power output, and enhanced fuel efficiency.
Why are NGK spark plugs better?
NGK spark plugs feature trivalent plating. This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal.
What is the top of the spark plug?
Terminal on top that connects the spark plug to the engine ignition source to generate the high voltage current for the spark. Center stem shaft that connects the terminal to the electrode. Housing or outer shell that supports the insulator, the grounding electrode, and the threads that mount the spark plug in the ...
Is iridium or platinum better?
Iridium is even stronger than platinum. It shares the same benefits over copper as platinum, but it is said to be eight times stronger than platinum, and it has a higher melting point so it can handle the hottest, highest-performing engines.
Which is better AC Delco double platinum or iridium?
Iridium spark plugs last long and perform well but cost more than spark plugs. They work well with vehicles with electronic distributor ignition systems. Platinum spark plugs don't last as long but are far cheaper and work better with vehicles that rely on waste spark distributor ignition systems.
What is the highest quality spark plug?
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
What are the signs of a bad spark plug?
What are the signs your Spark Plugs are failing?
- Engine has a rough idle. If your Spark Plugs are failing your engine will sound rough and jittery when running at idle.
- Trouble starting. Car won't start and you're late for work… Flat battery?
- Engine misfiring.
- Engine surging.
- High fuel consumption.
- Lack of acceleration.
What is the disadvantage of iridium spark plugs?
Cons of Iridium Spark Plugs
- Iridium spark plugs are much more expensive than platinum and copper spark plugs.
- In terms of like-for-like performance, an iridium spark plug is on par with a good quality platinum spark plug, which is usually available for less money.
What are the disadvantages of iridium spark plugs?
Cons of Iridium Spark Plugs
The best models use two or three layers of iridium on the central electrode, whereas the cheapest models may use only one thin layer. These can be prone to cracks and impact damage, so for the best results, always invest in a double or triple coated spark plug.
