For the most part, a throttle body is a throttle body. It's rare that they "break", and they're pretty much so simple, it would be amazing to me if there were any gains over competitor's throttle bodies of the same size. That's a pretty good deal. I'd buy it if it were offered to me. You might want to hold off though for a 75mm if you plan to go forced induction later. I have a C&L plenum, and it's great. No problems. fit perfectly. as far as a cold air intake, i'd recommend what I'm using, the C&L tru-fit inlet pipe with 85mm mass air. It fits phenominally well, it's really well crafted, and doesnt need to use your stock crappy plastic MAF housing like a lot of other cold air intakes (like BBKs for example, what a chunk of garbage.)
