Iridium plugs are a sure way to improve the combustion burn in your engine and may even smooth out minor misfires and cure running on problems.
The secret is an electrode tip made from Iridium which is a very hard material that can operate at very high temperatures (melting point 2400°C), therefor the tip can be a very small diameter, typically 0.4 - 0.6mm. This coupled with a sharp pointed side electrode provides excellent starting, better acceleration and optimum power.
