Spark Plugs, WTF
so i hit 40000km yesterday (24854 miles), and the weather was amazing today, so i decided to change my spark plugs to Bosch Platinium. easy job, but the Stock Sparks are sooo rusted. Is this normal for only 40 000 ? i mean the dealership only says to change them every 80 000km. so is it my driving or is it that the OEM plugs are crap ?
i changed my plugs 2 weeks ago for the first time since i'v had it and my car has 50k on it,they looked just like that too i also got the bosch plugs as well and it made a nice differance.next time i will get the iridiums when i can spend 50 bucks on plugs

Rep Power: 0 dont get bosch, car idling is very bad because they are a i think a european company, and your putting them in an import car? doesnt make sense does it? My vibrations went away as soon as I changed to denso iridiums. OMG so much better.

Dude, look a the tips. Those look burnt - as in either your car was running too lean, or your running too hot of a plug.....maybe try one grade cooler plug.

Bad plugs can reduce gas mileage. Mine were bad at 18K, all black. I suspect the car is running rich because of all the carbon. Good thing I'm getting it tuned soon.

Rep Power: 316 Spark plug analysis. This should help determine why the plug is fouling.

Rep Power: 0 Also, the plugs have had a good amount of time to sit in that aluminum head. and aluminum rusts 
. So here is was you should do. Ask for some spark plug compound that helps it resist in rusting, that way it is easier to pull next time.

Those spark plugs look fine. They looked burned, because they are. Why? Its in the combustion chamber. Duh. What happens in a combustion chamber? Fire. If the car is lean, it will be a lighter shade of brown. Rich, darker black. speckled usually means detonation. Also a statement like: "dont buy bosch, theyre a european company, and putting that in an import car is bad" is completely and utterly retarded. If its a european company, wouldnt that have to be imported too?! just like a BMW is an import. Its a european import not a japanese import. Since when have only asian cars been considered imports? And generally "Rust" as its called, is oxidized Iron (III). Also known as iron oxide. Aluminum oxide is not generally called rust in any sense of the term. Granted it is a similar chemical reaction. http://news-service.stanford.edu/new...minum-517.html has some good info about it.
