What Are the Differences Between Denso and NGK?
The main differences between Denso and NGK are their price and product availability. NGK spark plugs are generally cheaper than Denso spark plugs, although the margin isn’t much. Also, Denso has more than 200 subsidiary companies, while NGK only has 35 production plants.
Both spark plugs are known for their impressive quality and performance compared to other options on the market. They also differ in other ways, and here’s a more detailed account of their differences.
– Technology Used
Denso spark plugs are known for their unique design, which sets them apart compared to other options on the market. The plugs utilize a 360-degree construction made with iridium, which is a strong and durable material, and it allows the plug to last long. Denso spark plugs also have a low voltage requirement and high ignitability. With that being said, you won’t need to worry about losing power.
Another thing to note about the Denso design is that it has a twin-tip design, which allows the collaboration of platinum and titanium for a more robust spark. NGK does not apply this type of technology, but they are also ahead of most of its competitors.
The NGK spark plug utilizes a trivalent plating design that is resistant to moisture, corrosion, and chemicals. Basically, these spark plugs are designed to provide a better performance, especially in cases where there’s a need to go beyond limits.
– Product Line
Both companies also differ in the product catalogs they offer, even though they have so many amazing products in their respective collections. The two companies feature iridium spark plugs and platinum spark plugs, both of which are very durable and designed to last long.
However, in terms of diversity, NGK has a slight edge, and this is because of the ruthenium plugs they offer. These plugs feature the latest technology and enhance their performance and efficiency.
In addition to spark plugs, both brands also offer other vehicle parts in their collection. Denso takes the lead in this case, with more parts like engine cooling components, ignition coils, filters, sensors, and more. On the other hand, NGK only offers cutting tools, sensor parts, sensors, ignition coils, and wire sets in their collection.
Most spark plugs are placed under the same category when it comes to their lifespan. This mostly depends on the materials they are made from. For example, platinum plugs can last between 40,000 to 80,000 miles, while copper spark plugs can last between 20,000 and 40,000 miles. Durable materials like iridium and platinum can last up to 100,000 miles.
Denso and NGK spark plugs also follow this guideline. However, the focus of NGK plugs is on performance, and as such, they are more prone to wear and tear than Denso. Performance plugs will generally wear sooner than other plugs.
– Heat Range
As mentioned earlier, spark plugs facilitate the transfer of heat from the combustion chamber. Heat ranges describe the amount of heat that the plug disperses, and this is an area where the two plugs are different. When it comes to heat dispersion, there are only two types of plugs, which are hot plugs and cold plugs.
Hot plugs are designed to disperse heat at a faster rate, making them the ideal option for passenger vehicles. On the other hand, cold plugs transfer heat faster, and they gain more application in performance engines. With that being said, the heat range of Denso plugs is within the range of 9-37, where 9 is the hottest and 37 is the coldest. The heat range of NGK plugs is 2-12.
Basically, Denso plugs are the cold types, which makes them ideal for high RPM vehicles, while NGK plugs are mostly applied in passenger vehicles because they are hot plugs.
Denso spark plugs are more expensive than NGK spark plugs. However, this is not a limiting difference for Denso plugs because people still buy the plugs for other features they offer. For example, NGK plugs don’t last as long as Denso plugs because they are performance plugs.
It’s up to you to decide whether to pay more for a more durable plug and avoid changing your plugs regularly or less for a high-performance plug that is likely to wear out quickly.
It’s not easy to determine which spark plug is the best because they are both made from durable and high-quality materials. Also, both plugs are designed to improve vehicle performance. Denso and NGK are among the most popular brands on the market today, and the best depends on your preference.
A Denso plug will last longer than the NGK plug, which is why you’re likely to pay more for the Denso plug. In terms of performance, the NGK spark plug is the winner.
Another thing to note is that NGK boasts of ruthenium spark plugs, which use advanced technology to offer premium performance. All of these are factors to consider before determining which brand is the best for you.
