Changing the spark plugs

[Rpreme]

I’m ready to change the spark plugs on my 2011. Is there a difference or advantage on using the Denso Iridium TT (4704) vs the OEM Denso iridium long life (3421)?

Thanks in advanced!

I went with the Iridium TT for the second time. Not sure if there is really any performance benefit vs the OEM. The longevity was good with the TT, 120K miles, not that there was any issue with the OEMs.
