Spark Plug Change

[Chambers]

Yea, I would never run any Bosch plugs in a Supra of any kind, go for some NGK Iridiums, they will be a little more expensive but well worth it, they are high quality plugs. I don't have Iridiums but I have their regular plugs and set of their wires, they are both great!!

Good luck.

Be very careful with Iridiums. The slide gappers will damage them as they are soft. (that's the warning I had with them) But definitely go with Iridiums.

Are iridiums OK for NA Supras?

Yea, the NA will run them nicely.

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...
