can anyone tell my what is causing my sparkplug to go black. i just bought some and they turned black after driving for one month[IMG][/IMG]nnesotapictures052.jpg[/IMG]

 

how many miles on those plugs? they look older than "I just bought some and they turned black". and we would need some info on the car mods, if any.

your posts are outstanding today

 

Carbon deposits will normally turn a spark plug somewhat black. Your pictures are blurry, I can't tell if its oil or carbon. Is your car consuming any oil at all?

 

these are my old one, but the new one that i got, NGK iraduim, probably got about 2,000 miles, they tuned black to. im running msd ignition, s2s3 cams with complete skunk valve train and aem cam gears

 

no oil. just dry black carbon. im thinking im might need valve adjusted. any other possiblities?

How long has it been since the car had a fresh rotor and distributor cap?
Valve adjustment couldn't hurt either.

Better gas (with detergents/premium).

 

Valve adjustment, new dist. cap and rotor might help.

In all honesty, I think the MSD ignition is overkill for your setup. The OEM ignition setup is one of your cars strong points. Hell, theres guys running 600 whp, and the OEM unit functions just fine.

 

ive had the car for 10 months now and never replace the distributor. the last time i open the distributor cap it looked fine. i don't know about the rotor though.

The cost is so low, I would replace the cap and rotor. I'm not sure what the suggested interval for replacement is, but it's common practice to change them often.

 

msd came with the car when i got it. i did hear that the oems are better but what are the pros and cons of msd

 

for sure i need valves adjustment. how can you tell if rotors are bad.

It depends how your car was tuned. Some people have had ignition issues involving detonation, misfires, and tuneability problems. There really are no pro's to having it unless your making very high WHP numbers. I'm talking way above the 600 mark.

Personally, I would sell the MSD and use the money on something else. Then again, the saying "why fix whats not broken" isn't so bad in this situation.

As far as the rotor goes, remove the Dist. Cap and inspect the rotor for signs of corrosion and wear. They cost around $10 at the local auto parts stores. Or from Acura/Honda, where I would recommend purchasing, they are $15-$20.

 

thanks, i'll see what happens.
