agree. unless you scope your cylinder and see WAY BAD carbon there is little point. Add to that you don't destroy the carbon. you convert it to aerosol form and it all ends up in your cats.
if you have cats that are OEM you could (though only slightly) baf your cats and need new ones (codes).
no performance will be gained using seafoam.
Edit: if you are really concerned about gunk.. your MUCH better off having the intake and throttle cleaned by the NissaN\INFINITY dealership or by a GOOD tuner shop. seafoam won't clean the oil out of the oil channels in the intake .. they are separate. and unless you have a catch can it will have the customary 3-4 table spoons of dripping wet oil back in after 40 miles for hot driving.
