frequent questions
What you will explore here is a deeper dive into spark plug selection.
How do I choose a suitable spark plug?
It is important that a spark plug ignites the fuel at the right time and generates enough energy through combustion. It can work well in ideal conditions, that is, in hot conditions.
The question here is whether it can maintain such high performance in colder climates. Therefore, you need to consider the adaptability of spark plugs to any climate.
The next factor is which type is best for your car. There are three main types of anchor materials, including copper, platinum, and iridium.
Each type is the best option for specific cases. Copper spark plugs in particular are great on high compression but have a short life of around 20,000 miles.
Platinum spark plugs gain durability over copper spark plugs, as they can last for over 100,000 miles. In addition, the platinum material reduces the risk of deposit formation and improves flammability.
An iridium spark plug takes the life game to another level when it hits 125,000 miles. In addition, these plugs accelerate efficiently and consume economical amounts of fuel.
Of course, we all want the best, but large price differences can be a problem. The better the plugs, the more you will have to pay. Just be ready for such a date.
Along with compression, boost pressure is an important factor to check when choosing a spark plug. So copper connectors seem to have advantages here.
However, if you need a complete view, you can add the comparison of thespark plug gapwhere the spark discharge occurs. This element also contributes to the performance of the connector!
Are Bosch spark plugs good?
You can find the answer for yourself in our previous sections.
There is no question about the quality of Bosch spark plugs as they work very well even in cold conditions. This section is all about theBosch Dual Iridium Testdue to its excellent features!
The name reveals the main material, iridium, which guarantees a long service life. Add to that the four-pack design and 0.6mm fine-wire firing and the performance of a car engine.
This type of connector also reduces resistance to ground due to the copper core ground electrode and iridium inlay. Such a function does not affect the excellent performance, but reduces fuel consumption!
However, a comprehensive review requires considering its drawbacks. Prices for dual iridium spark plugs are among the highest on the market.
Also, the iridium material makes the connectors brittle if you are not careful during the installation or repair process. Another factor is combustible dust if it scratches the connectors against other components.
However, the durability of this component depends in part on its maintenance. So don't forget to check some characters e.g.oily spark plugsto keep them in the best conditions.
Bosch Platinum 4 Spark Plug Test
This spark plug has a center electrode with a significant platinum content, 75% more than Bosch platinum plugs. It also features a wear resistant nickel-yttrium alloy.
Exquisite design, allowing for different spark paths, optimizes flammability and combustion. The self-cleaning effect also contributes to a longer service life.
Bosch always tries to do what's best for its customers, so solid performance, even under harsh conditions, is what you can expect from a spark plug like this.
Another item to consider is whether it is good for a car engine. The answer is that a modern car will love Bosch plugs, but if it's a modified engine, that plug isn't ideal!
bosch iridium vs. NGK Iridium: pros and cons
These spark plugs are an amazing choice due to their clever design to optimize fuel economy and acceleration. Additionally, the iridium material extends the life of these spark plugs.
However, they are still supported in certain situations. In particular, the NGK Iridium IX spark plug will be an excellent alternative in the case of modified engines, since it is open to OEM replacement.
Meanwhile, Bosch Iridium spark plugs are not an ideal choice for older technology cars. However, it outperforms due to better features and functions.
Therefore, knowing which types of spark plugs your car is most compatible with plays an important role when choosing.
