10mm socket
socket extension
small flathead or pick

#1 remove silver engine cover: just pull it up from the back, there's just 2 "*****" that it snaps in and out of

#2 remove front plastic cover: this is held on with 5 clips. you just need to stick a small pick or screw driver in to the inner circle and pry it up, once that inner circle pulls up a little, you can pul the whole clip out

#3 remove the intake "y" collector: there's 2 hoses at the top you need to pull off (held in with spring loaded bands), the part on each side that connects to the air filter box is attached with 2 hose clamps (10mm bolt) and 2 tabs (just pull the rubber out and over the tabs to pull it towards you on each side). there's also a wire that is connected with a push in tab on the right side of the y collector, be sure to disengage that wire before you tug the y collector out. now you can pull the whole Y collector out.

#4 remove the stock intake resonator: there's a single 10mm hose clamp that you'll remove at the middle of the neck. losen the clamp and pull the old tube out and replace it with the new noise generator.

#5 reinstall: make sure that you align the little "spike" on the sound generator with the hole so it doesnt rattle, then be sure to re-clip the wire back in to place. everything else is just reverse of removal.
