Difference Between Iridium Vs Laser Iridium
Iridium and Laser are two types of ngk spark plugs used in modern vehicles. Both have unique specifications and capabilities, and they’re both high-performance spark plugs with long lifespans. NGK manufactures the Laser ngk Iridium ix whereas Autolite manufactures the Iridium Spark Plus.
Both are compatible with the majority of engines on the market today. They do, however, have certain differences, which are described below:
Brand
Both Iridium spark plug are from a different manufacturer. The Laser Iridium is manufactured by NGL, a well-known brand in the industry. The Iridium spark plug, on the other hand, is made by Autolite, a relatively new company on the market.
Although brands are irrelevant if the product is good, some people still believe in them. As a result, they may overlook the Autolite Iridium spark plug. However, based on our testing, both are good brands that provide excellent service.
Life Expectancy
The main difference between the NGL Laser Iridium and the Autolite Iridium Spark plug is their life expectancy—while the NGL Laser has a life expectancy of 80 to 100 thousand miles, the Autolite Iridium can last up to 40 to 50 thousand miles longer than its competition.
This is a significant disadvantage for anyone wanting to purchase the Autolite Iridium spark plug. The Autolite Iridium will erupt as it approaches 40 to 50 thousand miles. If you choose this plug, it is recommended that you replace it on time.

Core Material
The Autolite Iridium and NGK Laser Iridium spark plug both have an iridium core, the world’s rarest metal.
The NGL, on the other hand, has Laser Iridium, which is a more durable coating than Iridium. The coating on an Iridium ring lasts about five years, whereas the Laser’s coating can last up to ten years.
The core substance of the two spark plugs creates a significant difference in life expectancy; this is the only reason why the NGL spark plug outlasts the Autolite spark plug.
Gap
Another factor to consider is the gap between each brand. NGL has a 0.8 mm gap, while Autolite has a 1.3 mm gap. This means that Autolite will ignite more easily than Laser Iridium, but it will also wear out faster than Laser Iridium.
Not only will the Autolite Iridium spark plug ignite quickly, but you will also want a wrench that fits the size of this plug, in order to install it without difficulty.
Heat Range
The second factor to consider is the temperature range. NGL can only withstand 6 heat ranges. However, Iridium can withstand up to 32.
This means that if you have a large heat range engine, you should use an alternative like Autolite or NGL instead of Iridium, which only supports 6 heat ranges. This makes it easier for you to decide if you want something simple or something more complicated than what other manufacturers provide.
