    Is iridium is the electrode material, not sure what the b8 or zex means. I was hoping to get the NGK plug number, for example BK5RE-11? Anyone has a answer for the automatic transmission fluid query?
    Thanks for the quick response.

    I also need to know which is the right spark plug and tranny fluid for this same vehicle. As it turns out, mine is a JDM model with no english manuals.

    Anyone knows where i can find these manuals online?

The correct transmission fluid is ATF+4, any other trans fluid will spoil the transmission.
i use platinum spark plugs in my engine, works great.

1998 Mitsubishi Galant 1.8 GDI (EA1A model) starting problem. So it's not starting but turning engine over. Checked the spark plugs and they were oily. Cleaned them and still not firing. checked to see if...

Dude....putting 2 stroke fuel into a 4 stroke engine is just silly, but not where your problem lies. Check the coils to see if it is generating spark...if not then check the ignition module....even 'oily' the plugs should fire.

Spark plug location


They are right along the top of the engine going in behind the valve cover. They are deep down inside under the wire w/boot 2 of them have ignition coils on top of them (they are bolted down with 2 small bolts each) and have plugs plugged into them (1 each on outside edge) the other two are just beneith the rubber boots connected to the spark plug wire. Hope this helped you out. MWG
