How do I change out my spark plugs?

I can see the wires going in, but do I have to take off the intake??

Which are the best to replace the old ones with?

 

The best plugs for our cars are the ones that came from the factory, regular NGK platinums.

 

Spark Plugs are very sensitive thing, if I were you I would have a mechanic change them. I changed them myself but its a long story.

 

You can definitely change those plugs yourself if you are moderately mechanically inclined or can just follow instructions.
Check out this link, it has step-by-instructions:

Good luck and stick with NGK plugs.
