Just changed my plugs at 82K...nice results!

[DCopp]

took out my factory Champions (2001 LHS)and installed Bosch 4003 Platinum Plus($2.99 ea @ Autozone plus $1.00 per plug mail-in from Bosch) plugs and it was so simple. I had no troubles with the torx heads and was sure to use a new sharp bit with a T handle driver. Easy as pie!

Now the results...car starts faster and idles smoother so far. It also seemed that the accelerator required less effort and takeoff was instant! Very pleased so far...also Bosch has a three year warranty on this plug so another bonus.

here is a pic of the stock plugs...NOTE the one is hooked over! These all had a gap range of .070 or higher. I gapped the new ones just a hair shy of .050

Do you know of anyone in the history of the world that has ever collected on such a "warranty"? You did say it was a bonus, so you didn't let that make the buying decision for you.

I wonder if it is just coincidence that that plug is also discolored. What do you think?

DC,

Did you notice oil in the bottom of the spark plug tubes? That one that's hooked over looks like it's got dried on oil on the external portion. That oil came from somewhere.

You might want to keep an eye on it. The repair can be, uhm, rather involved.

No, I didn't notice any oil at all...I guess that is kinda weird that one plug would be like that. My car runs damn near perfectly so I am not too worried. Besides I am not sure what cylinder I took that plug out of anyways. Isn't it kinda funny though that the outer part of the plug is residued but the electrode part is normal in color? Where would the oil be coming from to get to that but not foul the plug?
