spark plugs

[valjo]

hellow!

i get some spark plugs for my s2. but they arent look like orignal s2 spark plugs. They are BOSCH SILBER, F3 CS 0241-255-505. they were fit to rs2, and they should be 2 degrees colder than original ones. What should it means for my car? could anyone please explain me that a bit?

regards

I have a question too about sparkplugs: Does anyone one of you suggest copper plugs for the RS2 and if yes what model? Are they better than normal Bosch F5PUR (or something like that) and how often must they be changed?
