this thing is 3 month old now...!!!!
Fitsay was open (last time i checked was last sunday)
but i guess it's down for somereason.
it's a basic bolt in mod, i'll try to explain "how to"

1. Remove the Stock Intake System.
a. Un Clamp the rubber stock piping from the Throttle body, and unbolt the filter box. Remove.
b. Remove the Front Bumper, unbolt 2~4 screws that is holding the Resinator box(this box cancels out sounds so your car is quiet), remove the box.
c. keep the bumper off till you finish the final installation
2. Open your CAI box if it's still in it. read direction if any came with.
a. see if they fit by just matching the parts out. and put them in order.
b. clamp on the bypass and the pipings together snugly, so that you can adjust the right/perfect fitment you want.
3. Reset your ECU.
a. Unplug the negative side of the battery for 5 mins, this will reset your ECU computer, it will also erase your radio station memory on your radio.
b. you reset your ECU so your engine adjusts to the new environment, I do this ever season, 4 times a year, spring, summer, fall, winter..and every other engine mods you do. it's not so crucial, but it is good for the engine.
c. after you reset it, re-connect the neg battery wire(Black one, and it's also a Gounding, you'll find this goes to no where but to your engine mount and chasis. your whole car is a grounding) and start your engine. let IT IDLE FOR 10 mins. don't give it any gas, just idle. and turn the engine off, and give it 3 hard runs red-lining.
4. Don't forget you put everything back togerher, this is crucial
a. check all the clamps and screws, make sure they are tight.
b. put the bumper back on.

I hope that helps a bit.
