Yes; iridium spark plugs are said to be the best quality spark plugs for fuel economy with platinum spark plugs being a close second. However, any new spark plug that is gapped correctly will burn the fuel/air mixture with great fuel efficiency.
What spark plugs improve gas mileage?
Getting some fresh spark plugs can result in better gas mileage, be it a copper, platinum, or iridium plug. However, a platinum plug will likely help you get away with more miles at a lower price, providing a positive effect on your gas mileage.
Do spark plugs help fuel economy?
Spark plugs are vital for engine performance. Without the spark that ignites the air-fuel mixture in the engine's internal combustion chamber, the engine cannot generate any power. Worn spark plugs drastically reduce fuel economy and increase driver costs.
Does iridium spark plugs increase mileage?
Iridium spark plugs give you even better gas mileage, performance, reliability, and longevity than double-platinum plugs. Iridium spark plugs are perfect to use on high-performance engines.

Why is my mpg dropping?
Here are some the main causes for a sudden drop in gas mileage: Bad oxygen sensor and air filters-in all forms will affect the fuel mixture and your fuel efficiency. Incorrect tire pressure and/or poor alignment-tires that have low pressure or are out of alignment can cause a drop in fuel efficiency.
Is Iridium IX or laser Iridium better?
Go with the laser iridium. The IX only last half the amount of miles or the Laser, so you replace them at a faster rate. Even if the IX produce better gas mileage than the Laser (which would be very difficult to measure) it wont make up for cost of replacing them twice in the same amount of time as the Laser iridium's.
How long do NGK Iridium plugs last?
