When should i replace spark plugs and torque specs for spark plugs?

[talontsiboy24]

I replaced them 2000 miles ago should i change them again sooner then the recommended 15k mark? My car has moderate mods so i was thinkin i need to replace them before 15k? Also what are the torque specs when tightening the plugs?

Don't they have a lifetime warranty? I would hope they last a damn long time .

I wanted to buy some, but actually I got mine for free from a friend. KV85's

I didn't know, but I just looked it up. They have a 10 year warranty. I think they could last much longer though, with a warranty like that.
