Anyone use any of these parts?

I was checking out all the parts on HTTP://home.att.net/~MabuhayCarlos and was wondering how these parts would really help...so here I am asking if any of you have bought these parts and if so, how did they help you...

I'd really like to keep my car all motor...sounds better when you tell a Mustang owner you just beat him with a 2.4L engine thats not running NOS or using forced air induction...
