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.

What’s better NGK or Denso?

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.

Can spark plugs increase horsepower?

When you change your worn-out spark plug with fresh spark plugs, you’ll notice a much faster engine response when driving. While spark plugs don’t technically increase your engine’s horsepower, they bring it back to its optimal combustion level.
