What is the disadvantage of iridium spark plugs?
Iridium spark plugs are often praised for their durability and performance, making them a popular choice for modern vehicles. However, like any automotive component, they come with their own set of disadvantages. In this article, we’ll explore the downsides of iridium spark plugs to help you make an informed decision for your vehicle.
1. Higher Cost Compared to Other Spark Plugs
One of the most significant disadvantages of iridium spark plugs is their cost. Iridium is a rare and expensive metal, which makes these spark plugs more expensive than traditional copper or platinum options. While their longevity may offset the initial investment for some, the upfront cost can be a deterrent for budget-conscious car owners.
2. Potential for Overkill in Older or Low-Performance Engines
Iridium spark plugs are designed for high-performance and modern engines that demand precision and efficiency. If you’re driving an older vehicle or one with a low-performance engine, the benefits of iridium spark plugs may not justify their cost. In such cases, a more affordable option like copper spark plugs might suffice.
3. Risk of Misfires Due to Wear
Although iridium spark plugs are known for their durability, they are not immune to wear and tear. Over time, the fine electrode can degrade, leading to misfires or reduced engine performance. Regular maintenance and timely replacement are essential to avoid these issues.
4. Installation Challenges
Due to their delicate design, iridium spark plugs require careful handling during installation. Improper installation can damage the fine electrode, reducing the spark plug’s effectiveness and lifespan. This makes professional installation a better option, which can add to the overall cost.
- Iridium spark plugs are more expensive than other types.
- They may not provide noticeable benefits in older or low-performance engines.
- Wear and tear can lead to misfires over time.
- Installation requires precision to avoid damage.
While iridium spark plugs offer excellent performance and longevity, these disadvantages highlight the importance of considering your vehicle’s specific needs and your budget before making a decision. If you’re unsure whether iridium spark plugs are the right choice for your car, consult with a trusted mechanic or auto service professional.
Frequently Asked Questions
Do iridium spark plugs improve gas mileage?
Switching to iridium spark plugs can considerably improve the mileage of the gasoline vehicles on the highway. This change comes from the fact that you now have a better ignition profile to ensure the efficient burning of the fuel.
What went wrong with iridium?
Because Iridium's technology depended on line-of-sight between the phone antenna and the orbiting satellite, subscribers were unable to use the phone inside moving cars, inside buildings, and in many urban areas. Moreover, even in open fields users had to align the phone just right in order to get a good connection.
Can I replace copper spark plugs with iridium?
Many newer cars cannot operate as designed using copper-core spark plugs, and they will experience issues with dependability. Most cars that take copper spark plugs can use iridium plugs, but they need to be the right size, voltage, and heat range. Only use spark plugs that are compatible with your engine.
Are iridium spark plugs good for older engines?
Yes, it is.
Also, older vehicles may well be suffering such problems as reduced ignition coil performance. An iridium spark plug with low required voltage uses the energy of the coil effectively for efficient combustion of the air-fuel mixture.
Do iridium spark plugs really make a difference?
Iridium is an extremely durable metallic element, which makes it a great fit as the material for spark plugs. The main property of the iridium spark plugs is that their electrode material comes with a high melting point. They offer a complete combustion and ensure a better performance.
What is the life expectancy of iridium spark plugs?
100,000 miles
Recommended Spark Plug Replacement Intervals:
Platinum Spark Plugs: Platinum spark plugs have a longer lifespan and may last up to 60,000 miles or more before replacement is necessary. Iridium Spark Plugs: Iridium spark plugs are known for their durability and longevity, often lasting up to 100,000 miles or more.
Which is better, an iridium or platinum spark plug?
To actually answer your question, iridums are better than platinum. Iridum is a harder metal, so it holds up better than platinum for long service intervals and iridum is a much better electrical conductor than platinum, making for a better spark.
What is the best spark plug for a Briggs and Stratton engine?
Briggs & Stratton Platinum Plug
The Long Life Platinum Spark Plug is better because it's specially designed for easy starts and long lasting performance in outdoor power equipment powered by today's 4-cycle engines.
What is the problem with iridium spark plugs?
This is potentially different from what advertising companies suggest, but the other metals are, unfortunately, not as conductive in general as copper is. Platinum and iridium plugs are more likely to overheat, which causes damage to the plug components and can compromise the delivery of the spark to the engine block.
What is the best spark plug for older engines?
Copper spark plugs
Copper spark plugs are also often used in older (pre-1980s) vehicles with a distributor-based ignition system. The nickel-alloy outer material used in the copper spark plug isn't as hard as other metals so it wears down more quickly with the high pressure and heat created in the cylinder of the engine.
