Time for new plugs?

[Calabria]

Ive had my car since March 07 at 106k, now its Sept.08 with 122k. I dont have any records of when the plugs where changed last, but im thinking new plugs are needed pretty soon. When my car is cold, it kinda 'knocks' or doesnt right when gassing it, but when its warmed up after a good 3-4min of driving around, its sounds normal. Plugs...yea or nea?

most likely "your" suppose to get 100k out of a set of plugs...

Change them and make sure they're gapped correctly, while you're at it I'd change the fuel filter and a few other things, but thats just me being anal.

Ya, i was thinking about chaning the fuel filter. My plugs might be from the factory...yikes.

Doesnt hurt to change them.

Bosch f6dtc. Great plugs. And I do not know how long factory plugs are supposed to last, but 100k are some endurance plugs. The f6dtc are good to 25k and do not need gapping. One step colder. I drove fine with them with and without a flashed ECU. BT guys love them too.
