Spark plugs are essential to the engine and play a significant role in car performance. They are always small-sized and connect to electricity through an arc-like path. Although small, they offer the spark that ignites and triggers the engine fuel producing a subtle explosion that helps the engine provide power.

There are a lot of different spark plugs in the market, but NGK and Champions tend to be the best and most competing ones. The two offer various benefits and options that render them less or more suitable for particular cars. The significant difference between the two is their heat ranges and the price. Champion spark plugs are long-lasting and do not need frequent replacements, while NGK is cheaper with good heat resistance, making them ideal sparks used by many car manufacturers.

Champion Spark Plugs vs. NGK: Major Differences


The NGK and champion spark plugs are made of different materials, while NGK uses nickel alloy with copper cores. Champions spark plugs use sintered metals produced from pressed powder metal.

Heat Dissipation Capacity

Resistance to corrosion

Champion spark plugs are designed to resist longer-term oil penetration and corrosion, while NGK offers little resistance. This is due to the fact that NGK’s alloys offer better resistance against wear and tear, as well as other environmental factors.

Comes along with Anti seizing

NGK TMP spark plugs are made out of authentic metal which doesn’t corrode, and they have an ultra seal housing to ensure that the protection against corrosion is maximized. On the other hand, Champion’s TinTac and Ultraseal housing protect Spark Plugs from corroding in any way.

Extended Shelf Life

NGK spark plugs are a big catch because they have Platinum welded to their back. This helps them last longer while also securing it from the ground. However, Champions managed to give an impressive service thanks to their copper core heat control system.

It has a small diameter central electrode that was designed to improve starting and anti-fouling.

Longer life

Champion spark plugs are built with the copper core as their centre. It allows for the precise number of heat range control that prevents them from melting and avoids malfunction. They also have an extended service life, which is likely because they use a higher-quality electrode than other brands.
