spark plugs

^^ Yeah, I misunderstood her post too. But I agree, run too rich and the plugs foul up. The reason for running rich is to protect the engine from preignition, but that means that you need colder plugs, which end up fouling quicker. What boost pressure are you running? Reduce it slightly, which means you shouldn't need to run as rich and you can also go to a slightly cooler plug.

Effects of boost, running too rich, fouls the plugs real quick.
That's why most boosted car run copper plugs and change them very often.
I rem my old car killed the platinum ones in under 2,000km.
If you get the car tuned for the plugs you shouldn't have as much issue though.

Yeah as arrong said, fuel is different, but your prob not sparkign the fuel due to your plugs fouling and its flooding the engine

i dont really understand wats goin on all i noe is i have to change them alot

oil change every 5000 and looked like sprak change every 2500
the car got retuned on wednesday with the plugs so im hopin this is better
my first tune was with platinum plugs which failed fast

What spark plugs are running now? The exact part number if possible. Also, what are your AF ratios?
