I would like a correct name of the plug since i need a new set of wires and plugs...misfire is pretty bad.

Any real input instead of copper platinum copper platinum would make this thread more beneficial to others

3 methods to do this:

method 1 (most number of steps)
step1, remove stock plug, step 2, read name on side

method 2
use search function at the top of this page

method 3
Let me google that for you

I tried the E3's, seems to start quicker and a smoother idle with A/C on. I had a problem with the #1 cylinder though, the seat on the E3 is higher on the body then oem plug so it sits lower in the plug valley. I had to trim down the boot a bit on the plug wire.
