what is the gapping on the spark plug for the p5 (which im assuming is all the same) and can i get any platinum plug or whatever? reason being, i think all those miles without the CEL fix fouled my plugs pretty good. im leaving in about 35 minutes so i appreciate the response and im a bit busy to search cause the wife is making me take out the dogs THANKS!

.044 Is the gap. Should work, if you buy it specificaly for the p5. Otherwise you might have to set it.

Yeah , just make sure the gap is right. If there is some like deposits or burn marks they might have gone bad.

Why would your plugs be bad already thoe? No detonation from boost or anything. How many miles like 6K should be alright still. Platinum's will last longer supposedly, maybe give 1 hp.
Reading a plug pretty much follows as:
Normal-deposits will be gray to brown and slightly flaky
Any thick oily black deposits would say your engine is burnig oil and may have bad ring seals (this was the case on my Saturn, the WHOLE plug was covered in oil)
Electrodes that are black will tell you the engine is running rich.
If the Electrodes are yellow and hard/cracked then it is to lean.

What he said .
well i couldnt change them cause the auto center was closed for maintence, damn cause i was gonna change my oil to mobil one as well.
i thought because i was running so rich from the CEL i wouldve fouled the plugs. i bought bosch platinum +4, it was the best they had.

Quite possible.
bosch is s***, so is that autolite s*** or champion for that matter... s*** electrode designs... makes a lot of imports run bad... particularly noticable with turbo engines
get NGK or denso NORMAL spark plugs... none of that fancy platinum s***... they're a waste of money and add no performance... the normal s*** is cheap anyway... the gap spec is 1.0-1.1mm

nice, I was about to go get some plugs and with the imports I have had I have gotten nothin but NGK in the past, was thinkin of denso now but will just see what the local places carry, hell since I dont need em right away I might shop around online a while.
Besides switching from N/A to boost or increasing the hp significantly is there a standard time or whatever for when the plugs SHOULD be changed out?
I mean are the stock plugs bad enough that you should go ahead and change whenever you can or will it not make a single difference?
not like their expensive or anything.

I had denso iridium's in my old protege , put them in at about 20k miles. They seem to smooth out the idle, etc.
people who talk s*** about the stock spark plugs don't know anything... not only are they cheap, they're actually damn good for conventional spark plugs... they're actually NGK V-Powers according to the part numbers... and as for that iridium s***, you don't need it unless a) you like to waste money b) add more crap to your sig c) legimately have lots of engine mods to benefit from it
and if you "feel" like the car ran better with it its 1) brand new spark plugs, of course it'll run better! 2) cognitive dissonance because they wasted all this money on something fancy sounding
