Spark Plug Change

[Mahonri]

What about the E3's with diamond fire technology? Im not sure since I have not looked them up for the supra, but what I was told from a friend that races old school muscle, they work like a charm and have really nice power increases. e3sparkplugs

Update: They do have them for all years/models for the Supra. Interesting comparison that the series "Horsepower" did between the E3's and I'm not sure of the other brand.

Im not an expert, but I believe that platinum spark plugs will perform as well as E3's, so the E3 should be ok for a Supra, however, I dont know if they will outperform the Iridiums...
