I have found that compared with the OEM nickel alloy electrode spark plugs, switching to Long Life Iridium plugs with a fine wire iridium-tipped center electrode, a platinum pad ground electrode, and an extended projected tip provides a noticeable performance increase. Specifically, an increase in acceleration in all modes and a quickened throttle response has been noted.
For a discussion of the factors underlying this beneficial change, I suggest the following two references:
The spark plugs I'm using now are Denso Iridium SKJ16CR-L11.
Obviously, for engines already OEM-equipped with Long Life Iridium plugs such as those in the Mazda3 or 6, this option is not available.
Happy Motoring!
