who do you think makes the best plugs for our cars? i was thinking pulstar iridium but i see many people use NGK

 

NGK or Denso. As long as the plugs you're using has the right spark that the car requires, then that's all you need.

I personally use NGK because they're cheaper to buy and they work great.

 

Keep in mind...The purpose of the spark plug is to provide ground for the secondary ignition circuit. Using anything other than OEM is not gonna justify anything. Just use the Nippo Denso Long Life Iridium and your good for 100k+ miles that's first recommended by OEM. Second recommended by OEM is NGK Iridium.

Denso Iridium, i wouldn't use anything else personally.

 

I just bought some Denso Iridium man are they expensive! but i installed them! replacing the original OEM ones (137000mi) and man do i feel a difference, im going to replace my plug wires with denso aswell!

 

I've been told by many of the supra guys, and techs at a local race shop that an ngk copper is best

 

i just go by whatever's printed on the little sticker under my hood.

 

There's a whole spark plug review thread in the Maintenance section if you look for it..

 

Best spark plugs for stock? I'm sure it's going to be OEM. What are they worth at the dealer these days? $15 a plug and a left side nut?

 

Denso plugs nothing more nothing less. Just because they come in a toyota box and I get them for 16 bux for all six.
