2006 Nissan Sentra Question: Iridium Spark Plugs Installed: Is it bad?
Iridium spark plugs are the best plug made. many auto technicians do not like Bosch Platinum or the four prong Bosch plugs in Asian cars. The spark plugs you have if they are the right application for your car are the best and should not require changing as frequently as a standard plug. - patrick mannion
