Does iridium spark plugs increase power?

Iridium spark plugs can enhance engine performance by providing a more reliable spark due to their superior conductivity and higher melting point compared to traditional spark plugs. This can lead to improved combustion efficiency, better throttle response, and potentially increased power output. However, the extent of the power increase may vary depending on the vehicle and other engine conditions, so the benefits might not be significant for all applications. Overall, while they can contribute to better performance, they are not a guaranteed power booster.
