If it is a brownish hue what does that mean?

Its normal. I wouldnt worry about it. Do you notice any issues with the car?

I would replace the plugs with something a little better than motorcrap brand. You have any mods?

i have an exhaust system and headers and cold air intake. it feels like its lagging when i get on it. idk what it could be though. i just replaced the fuel filter.

i checked the gapping of the old plugs and there off by .10, is that a big diff and can cause any trouble?

That's pretty significant. Try a .054". And stay FAR away from platinum plugs. Assuming you are NA, go with copper. Just be advised that copper plugs need to changed about every 10-15k miles.

As for the lagging, it might just be a bad batch of gas.
