Do Iridium spark plugs increase horsepower?
Iridium plugs take less voltage to fire which results in more coil dwell time. That translates to better combustion, lower emissions, better fuel economy and more horsepower. Lower your costs. It’s true – buying an upgraded plug does cost more than a basic spark plug.
Do NGK Iridium plugs need to be gapped?
In most cases your Iridium Power plugs do not need to be gapped. … Should you decide to re-gap your Iridium Power plug, use extreme caution as improper gapping may damage or destroy the Iridium center electrode or porcelain center.
What is the benefit of iridium spark plugs?

The ultra-fine center electrode of an Iridium Plug ensures fast ignition and improves the engine’s starting characteristics.
Are copper spark plugs better than Iridium?
Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs. In reality, copper has the best performance of all three and the worst longevity.
Do Iridium spark plugs really make a difference?
Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs. Iridium spark plugs feature a fine wire center electrode that is designed to conduct electrical energy better and increase firing efficiency.
How do I know if my spark plugs need changing?
Here are seven symptoms that let you know it’s time to replace your spark plugs.The car is hard to start. … The engine misfires. … The car gets poor fuel economy. … Rough engine idle. … Your car struggles to accelerate. … The engine is really loud. … Your ‘check engine’ light is on. … Frequency of replacing spark plugs.
What happens if you don’t replace spark plugs?
Spark plugs will deteriorate over time, so if they are not replaced, various engine issues will arise. When the spark plugs do not spark adequately, the combustion of the air/fuel mixture becomes incomplete leading to loss of engine power, and in the worst case scenario the engine will not run.
Is NGK Spark Plugs good?
The NGK 6619 Iridium IX Spark Plugs snags the top pick in our spark plug comparison because they offer the best mix of high-performance, fuel efficiency, durability, and dependability. Featuring an iridium construction, these high-quality spark plugs provide a longer lifespan than copper and platinum spark plugs.
Is NGK better than Denso?
Both the Denso and the NGK spark plugs are crafted of iridium– with metal that is a lot less conductive than copper- but has better longevity, and a capacity to work at a lower temperature. While iridium spark plugs may not be the best when it comes to performance, their longevity is second to none.
How long does NGK Iridium IX last?
40-50k milesNGK Iridium IX has an iridium center electrode, however the ground electrode is a traditional nickel construction. Therefore, the ground electrode will wear out first. NGK gives them a life expectancy of 40-50k miles.
When should I replace my NGK Spark Plugs?
NGK recommends that all spark plugs of a vehicle are removed for inspection every 10,000 km. – Best staring; – Fuel economy; – Lower operation voltage.
Should I replace all spark plugs at once?
Spark plugs are cheap, you change them in sets as you do with brakes or spark plug wires. You want all of your spark plugs to match and have nearly the same levels of electrical resistance as all of the other plugs. This make the engine run smoothly. … This gives you efficiency and as well, longevity, with your motor.
Do Motorcraft spark plugs come pre gapped?
The fine tip iridium are always pre-gapped at factory and the manufacturers specifically say that should NOT be messed with by user. The Motorcraft ones are cheap versions of Autolite Dual Platinum, they requested “no factory gapping” to their OEM (Autolite) to save costs, that’s why the gap is never exact.
