a lot of people say that the c&l mass air flow sample tube for 30# injectors isnt good but mine has worked perfect and is awesome but your probably not looking into that, i figured i would just it, but if you just want the cai and the true flow pipe, it is f'n great, its an huge filter that goes on your mass air and flows really good and the true flow pipe is made of cast aluminum and works great and looks sweet, i actually gained a few numbers from just the filter and pipe, i had the mass air and when my car was getting tuned i bought the c&l true flow kit and i had my tuner switch it out half way through when i had the custom dyno tune done
