i've been using the trick flow street heat intake for a little over two years now, with only one slight compalint. it came with those damned 12 point bolts. i replaced them with good old fashioned hex bolts from home depot, and i took the two long upper intake bolts and ground a notch into them and touched them up so they look like regular flat head screws. i used nitrous on the car with the stock intake and with the trick flow, and on top end i noticed a major difference with the trick flow intake. it absolutely howls on top end. you'll be happy with it. i don't plan on changing it regardless of what future mods i do - unless of course i come across a deal that's too good to be true.
