New plugs

Yesterday I changed out my bosch platinums with less than 3000 miles on them and was completely unsatisfied. I got the NGK TR55 and when I started it up to take a drive it was fine until I left my driveway (wasn't warm yet and it was below freezing) in third gear it made this weird noise coming from the passenger side front, sounded kind of like an exhaust leak then it went away. Sounded like a truck. When it warmed it ran great, I haven't driven it today when it is cold so I don't know if it will do it again. Is this normal or what could be wrong?

RE: New plugs

Are all the plugs properly torqued and not cross threaded?

RE: New plugs

That sounds like the compression is blowing out from the plug. Make sure you have them all tight, right away.If not you could blow a plug and thats not fun at all.

That is what it sounded like, but today it didn't do it when it was cold. It only did it for less than a minute. I know I torqued them real good. But all is normal now, you guys think i'm fine?
