On the other hand, platinum spark plugs are usually less expensive than iridium, and they tend to perform well in normal engines, as well as engines with high-compression.
Ultimately, the best choice for you depends on your engine requirements, and your budget. Doing some research into the type of engine and spark plugs that would work best for you is often the best way to determine the best type of spark plug to use.
What are the spark plugs for horsepower?
Spark plugs provide a spark needed to ignite the air-fuel mixture in the combustion chambers of an internal combustion engine. The voltage needed for the spark to take place is created by the ignition system, and sent to the spark plug via a spark plug wire.
A spark plug is used for each cylinder in an engine, and having the correct type and amount of spark plugs is important for ensuring the engine runs efficiently and produces the correct amount of horsepower.
A spark plug’s heat range is related to its ability to dissipate heat away from the tip, and is a key factor in the performance of an engine. The heat range of the spark plug affects the performance of the engine and the ability of the spark plug to control the combustion process and eliminate pre-ignition and fouling.
If a spark plug has too low of a temperature rating, it will not stay at optimal temperatures during conditions of full power and may cause pre-ignition or over-heating. If a spark plug has too high of a temperature rating, it may cause the spark plug to become excessively cold and may leave deposits on the plug and cause fouling.
Matching the heat range to the needs of the engine along with the proper gap setting, electrode type, and spark plug design are important for maximizing horsepower and engine performance.
Do iridium plugs make more power?
Iridium plugs are known to improve the performance and fuel efficiency of an engine, although they may not necessarily make more power. Iridium plugs offer a number of advantages over traditional spark plugs, including improved spark-to-idle performance, improved fuel efficiency, and a longer service life.
The improved spark-to-idle performance is due to the fact that iridium plugs conduct electricity better than traditional plugs, resulting in a higher and more consistent spark. This in turn results in better combustion of the fuel, which leads to better fuel efficiency.
The longer service life of iridium plugs is also attributed to their improved conductivity, as they are able to withstand more heat than their traditional counterparts before deforming.
In summary, although iridium plugs may not necessarily increase the power, they do offer a range of benefits that can improve a vehicle’s performance and fuel efficiency.
How do I choose a spark plug?
When it comes to choosing a spark plug, the biggest consideration that needs to be taken into account is what type of engine your vehicle has. Different engines require different spark plugs, and using the wrong one can result in engine misfiring and very poor performance.
Generally speaking, modern petrol engines use one of two types of spark plug – copper or platinum/iridium. Copper plugs are cheaper but only last around 10,000-20,000 miles before they need replacing, whereas platinum/iridium plugs can last up to 50,000 miles.
In addition to engine type, the other main factor to consider when selecting a spark plug is its heat range. The heat range of a spark plug refers to the range of temperatures in which it can operate optimally.
Generally speaking, a hotter spark plug is better for a vehicle with a higher compression ratio, while a colder plug is better for lower compression.
When choosing a spark plug, it’s important to make sure that you select the one that’s right for your engine type, and also double-check the heat range as well. Also, consider the general wear and tear when selecting a spark plug – if you are planning on taking long trips or doing hard, off-road driving, then a spark plug with a longer life expectancy might be the better choice.
Finally, always check the manufacturer’s specifications for the exact spark plug type, heat range and any other relevant information before buying it.

What is an iridium spark plug?
An iridium spark plug is a type of spark plug that utilizes an iridium-tipped center electrode to provide superior performance compared to conventional spark plugs. The center electrode, which is responsible for sparking and igniting the air-fuel mixture in the engine’s combustion chamber, is made of iridium instead of much cheaper materials like copper or nickel.
The iridium material provides superior wear resistance and a much sharper, narrower focused spark, resulting in improved ignitability and performance. Better ignitability improves throttle response and acceleration, and the iridium spark plug’s sharper, narrower focused spark reduces the amount of unburned fuel that’s expelled through the exhaust, resulting in reduced emissions and improved fuel efficiency.
In comparison to conventional spark plugs, iridium spark plugs also have an improved energy channeling capability due to their longer insulator neck and tapered seating design, resulting in improved anti-fouling performance, improved cold starting and improved overall performance.
