The Best Spark Plugs in the World and Why

Where is NGK made?

NGK is a manufacturing company based out of Nagoya, Japan. The NGK Spark Plug manufacturing plant opened in Sissonville, West Virginia, in 1995. The Sissonville plant now produces oxygen sensors and spark plugs for internal combustion engines, along with ceramics and applicable products.

Is NGK an OEM?

OE-Style Spark Plugs - NGK Spark Plugs. NGK spark plugs come standard on more vehicles in North America than any other manufacturer. The OE-style spark plug line brings that original equipment spark plug to the automotive aftermarket, delivering OE fit, form, function and performance for your engine.

Is iridium or platinum better?

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.

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.

Do spark plug brands matter?

Although many motorists and technicians prefer to stick with the same brand when replacing spark plugs, there's nothing on the label that limits a particular brand of plug to a particular vehicle make or model.

Do expensive spark plugs make a difference?

This would be more accurately described as “less performance loss.” Spark plugs do not increase the performance of an engine — even spark plug manufacturers are fairly forthright about that. Noble metal plugs can perform consistently and well, which helps to maintain the engineered performance of the engine.

Are DENSO spark plugs Made in Japan?

All DENSO Spark Plugs are manufactured in Japan, Indonesia, China and USA. If a part claims to be a DENSO component but has been manufactured outside of these areas, then it is not genuine.

Is Laser Iridium better than Iridium IX?

How long do NGK iridium plugs last?

NGK gives them a life expectancy of 40-50k miles. But they have to temper their projections as driving conditions and motor modifications differ. Typically we have found you can expect 60,000 to 80,000 miles on an unaltered motor.

What's better 7mm or 8mm spark plug wires?

A more robust core provides a lower resistance path for the power, thereby allowing more power to reach the spark plugs. Additionally, the 8mm wires have a thicker outer coating that keeps the core safe from damage. These wires also have a thicker layer of suppression material.

How long does DENSO iridium last?

All Denso long life iridium spark plugs are an OEM design, made for a specific engine. Some feature a special resistor or electrode design, depending on the OE requirements. In their OE application, Denso's long life plugs can last up to 120,000 miles.

Are twin tip spark plugs better?

In technical terms: The Twin Tip design delivers far less obstruction to the spark allowing an omni-directional explosion. This minimizes the quenching effect and results in a more effective, more complete combustion.

What spark plugs are 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.

Do iridium spark plugs increase horsepower?

Yes, NGK iridium spark plugs can increase horsepower. By providing more spark to the firing tip, you combust more fuel, producing more horsepower.

What are the 3 types of spark plug?

Nowadays there are different kinds of spark plugs available in the markets to choose from i.e. copper, platinum and Iridium spark plugs. The copper spark plug is the most commonly used spark plug as it is the cheapest among the three.
