Following the 122nd Ordinary General Meeting of the Shareholders on 24 June 2022, NGK SPARK PLUG announces major news with its decision to change its English language company name to 'Niterra'.

U-Groove spark plugs meet original equipment replacement intervals and original specifications on your Toyota. Select Toyota models feature the distributor-less Toyota Direct Ignition System (TDI).

The design of the two brands also differs, with NGK using a nickel alloy with copper cores, while Champion spark plugs use sintered metals produced from pressed powder metal. In terms of heat dissipation capacity, Champions feature better performance and prolonged usage in even higher temperature conditions.

Iridium Spark Plugs Are More Efficient

Iridium spark plugs are better at starting engines than other types of spark plug because the spark is highly concentrated in the central electrode, and consequentially requires less voltage to operate.

NGK Iridium IX has an iridium center electrode, however the ground electrode is a traditional nickel construction. Therefore, the ground electrode will wear out first. NGK gives them a life expectancy of 40-50k miles.

On November 11 1936, NGK SPARK PLUG Co., Ltd. was founded in Nagoya, Japan with a start-up capital of one million yen. Only a year later, the young company already began delivering its first spark plugs; the cornerstone for future growth.

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.

Who is the number one spark plug company in the world? ›

For this reason, Denso plugs won't last longer than NGK units but they will be better at producing powerful sparks. On the other hand, NGK plugs will be a standard replacement for their platinum alternatives. They require less maintenance and provide a more stable and consistent performance than a Denso.

NGK spark plugs feature trivalent plating. This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal.

Accordingly, the global brand NGK Spark Plug Co. LTD. also will begin operating under the English tradename Niterra Co., Ltd on April 1, 2023. “It is an exciting time in the long and storied history of NGK Spark Plug.

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.

What is 1st position in spark plugs? In most engines the number one spark plug is in the number one cylinder which is the forward most cylinder at the front of the engine. In V engines the cylinders are offset from side to side.

Typically the heat range for NGK Spark Plugs varies from 2-11. This number indicates the thermal characteristics of a spark plug, or how 'hot' or 'cold' a spark plug is. The term hot/cold is commonly used to describe whether a spark plug heats up easily (hot) or whether it provides resistance to heating up (cold).
