Which is better Denso iridium or NGK iridium?
Which is better Denso iridium or NGK iridium?
Denso plugs are installed on almost every automobile model manufactured in Japan. The iridium used in them has a superior hardness. The electrode’s diameter in these plugs shrinks more than an NGK. For this reason, Denso plugs won’t last longer than NGK units but they will be better at producing powerful sparks.
Which plug is better platinum or iridium?
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
Are ruthenium plugs better than iridium?
Iridium spark plugs are the better choice for high-performance engines, while Ruthenium spark plugs are a good option for most applications. Both materials offer durability and resistance to corrosion, making them a good choice for most vehicles.
Which Iridium spark plug is best?
NGK 6619 Iridium IX Spark Plugs snagged the top pick in our spark plug comparison because they offered 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.
Which NGK plug is hotter?
On NGK spark plugs, the lower the number the hotter the plug (higher numbers are colder). Thus, your NGK BR9ES is colder than a BR8ES.
What does the R mean in NGK plugs?
Resistor
[R] Resistor – If an R is present, this indicates a resistor type spark plug. Resistor type spark plugs reduce the amount of radio frequency interference (RFI) that can cause ignition misfires and static on the radio.
What spark plug is better than iridium?
The platinum increases the durability of the plug, adding 100,000 miles to its service life. Platinum spark plugs can generate more heat than their iridium counterparts, ensuring lesser buildup of debris. This kind of spark plug is best if you have a new car equipped with an electronic distributor ignition system.
What is the difference between NGK iridium and Laser Iridium?
These two plugs perform similarly, due to their fine-wire tip design, but the service interval is different; the Laser Series are typically designed to last 80 to 100 thousand miles, where as the Iridium IX® spark plugs are designed to last 40 to 50 thousand miles.
Who makes the best spark plugs in the world?
