BTW people dont buy those E-3 spark plugs that cost like $15 each. Complete waste of money. Put them into my prizm. Actually made the car work worse. Less power/same mpgs.
Electricity takes the path of least resistance, having multiple electrodes doesn't do shiz for a standard engine. Direct injection engines have a slight benefit to them but that is only due to the spray pattern inside the combustion chamber.
Putting in new spark plugs will do nothing but reduce any misfires that your previous plugs could have made.
The E3 Plugs show they explode inside to outside, this is not true, as the fuel would have to be sprayed right onto the spark plug to make that happen. If that were true the spark plug would foul.
It probaly made the prizm run worse because the gap was not correct. The gap could also not be adjusted by you.
