Hi, I am new to this website and I am relatively new to the car scene. I have a 2004 trailblazer LS, and it has the 4.2 I6. I was wondering, if there are any performance parts out there that could make my trailblazer a little bit more faster? I'm not looking for a supercharger or anything like that, I'm just looking for things to install that could give it just a little bit more power, I know a performance intake could do me some justice but thats all I really know, so if anybody has suggestions I would love to hear them because I have a hard time finding performance parts for my trailblazer. Thank you all.
