Denso Platinum TT Plugs
 

i'm gonna try a set of these...https://www.densott.com/ for my next um...experiment.

might prove to show no gain in FE, but advance auto has them for $1.99 each until the end of june. not bad for a platinum plug.

well i bought my set before the sale ended. the ground electrode part of the TT or twin tip looks like they pressed a die into the top of it to create the additional tip.

i won't be testing(installing) them right away tho because i had to purchase a couple of tires today. this obviously would interfere w/ true testing. stay tuned...

installed them last fill-up...no noticeable difference...of course.
