While their performance level is almost consistent, they cater to different performance needs and engine requirements. We took time to dig into NGK V-Power vs G-Power to find out how they differ.

NGK V-Power Overview

NGK V-Power spark plugs come in a unique V-shaped design on the electrode, which enhances ignitability and reduces quenching. NGK V-Power spark plugs are known for their better fuel efficiency, improved throttle response, and overall engine performance. These spark plugs are available for various types of vehicles, including cars, motorcycles, and other gasoline-powered engines. So, are NGK V-Power spark plugs good? Let’s find out!

Key Features of NGK V-Power Spark Plugs

Trivalent Metal Plating

Trivalent metal plating is a protective coating applied to the surface of spark plugs through an electroplating process. This plating consists of trivalent metals, typically zinc. The primary purpose of trivalent metal plating is to provide a durable barrier against environmental factors such as moisture, chemicals, and heat.

Furthermore, trivalent metal plating helps to reduce the risk of seizing, which occurs when two metal surfaces become tightly bound together due to corrosion and other factors. Seizing can make it difficult to remove spark plugs during maintenance or replacement, leading to damage to the engine.

Corrugated Ribs

Corrugated ribs are raised, rib-like structures incorporated along the ceramic portion of the spark plug to prevent flashover. A flashover occurs when the spark jumps to an unintended path, leading to misfires and reduced engine performance. The ribs help to ensure that the spark travels along the desired path without straying to unintended surfaces, such as the insulator or cylinder head.

Pure Alumina Silicate Ceramic Insulator

This insulator separates the central electrode, which produces the spark, from the metal shell of the spark plug. The use of pure alumina silicate ceramic provides superior strength and better heat transfer properties. This ensures the spark plug can withstand high temperatures and thermal cycling without compromising performance.

Copper Core

Copper is an excellent conductor of both heat and electricity. When used as the core material in a spark plug, it facilitates the efficient transfer of heat away from the tip of the electrode and into the surrounding metal shell of the spark plug. It also helps dissipate excess heat generated during the combustion process, particularly in high-performance engines or under heavy load conditions.

Triple Seals

NGK V-Power spark plugs are equipped with triple seals to help maintain proper compression and prevent damage to the spark plug and other engine components. The first seal is used to prevent the escape of combustion gases from the combustion chamber.

The secondary seal serves as an additional barrier against gas and oil leakage. On the other hand, the third seal is specifically designed to prevent engine oil from seeping into the combustion chamber or onto the spark plug’s electrode.
