::Im not a mechanic so if u screw somthing up, its YOUR fualt

ok so ive done 4 of these now on three gen3s and my gen4, so i figured i share the...well whatever u wanna call it.
now this example is on a gen4 V6 that already had a SIR so i had no need to relocate hoses. ill explain how to do this when it comes up. the I4 will work to but the process is a little different.
Cost: (most things can be bought at a hardware store)
3" dryer tubing- $8
heat insulation tape- $3 (used to wrap the ducting in the engine bay)
3" C clamp coupling(ineeded 2 since i had a SIR already)- $4
reusable cone filter - $25
Items needed to run hoses if needed:
2 brass hose nipples(3/4" i believe/hardware store)- about $3
hi-temp, silicone sealant - $3
Tools needed:
philips head and flat head screwdrivers (short ones will be needed for the gen3)
ratchet set w/extensions (ull mostly use 10mm)
wrenches woud be usefull but a skinny pair of pliers will do(for the fuse box)
ok so once uve organized ur parts and tools, either lift the front end and remove the drivers wheel(perfered) or turn the wheel all the way to the right.
1. disconnect battery and remove.
2. disconnect the intake tube from the airbox, pop the clips off the lid of the airbox and remove the lid and airfilter(leave intake tube in place, it holds most or all of the hoses)
3. there are 3 screws holding down the botton half of the airbox, unscrew these and remove the rest of the airbox(ull prolly need the extensions for this)
3. remove lid to main fuse box(gen3 has 2 separate boxes), then remove the screws holding the fuse box down.
4. at this point go underneith the car and remove the screws that hold on the black plastic splash/debris guards infront of the drivers wheel. should be 4 underneith and 3 in the wheel well. disconnecting the left side of the bumper would help too.
5. next pull the plastic in the wheel well aside and ull see the moisture collection/silencer. remove this screw illustrated in red. the front is held in a clip which can be pulled out when u pull the unit toward the wheel. its also slipped into the the intake which just slips off. (
the gen3 is a little tricker to get off and requiers removing 4 screws from the front and back fo the unit, ull need the short philips for this)

6. once u have removed the silencer its time to remove the remainder of the intake. the gen3 is easier to remove. the gen4 has a clip that holds it down that u can get to from under the battery tray. it takes some work but with the battery out and fusebox unbolted its pretty easy (removing in a rearward direction is the best way to get it out). this is the piece ur taking out.
7. now uve got it all out its time to run ur tubing. the gen 4 takes a little more work then the gen3 to snake it into the fender. on the gen4, make sure u release the wire harness(white clip acessable from fender) and push it OVER the tubing as u snake it into the fender. start from the engine bay and twist the tubing back and forth making sure u use ur other hand to guide it into the fender correctly from inside the fender. the gen4 is a tighter fit and may dent the tubing but wont damage it. TAKE YOUR TIME, rushing it will tear the tubing and make a headache for urself for both gens.

8. use the 3" coupling C clamp to attach the filter to the tubing. easiest way is to attach the clamp to the tubing first then attach that to the filter. now i used zip ties to elevate the filter and possition it in front of the bumper vents(gen3) but u can use whatever u want to do it.
in the event that u need to run hoses, simply make a hole in the tubing and insert the threaded side of the brass hose end nipple into the tube then use silicone sealant to seal and hold it in place(epoxy works too). then just connect the hoses.
replace the fuse box and battery and fire her up. if all hoses are plugged up right then ull have no codes and will be taking in cooler air for a fraction of the cost of prebuilt CAI.
thats about it. its ghetto and doesnt look the best but its the cheapest and in some cases one of the only ways to do a CAI. ive hd this same setup on 2 gen3s for over 2 years each and ive never had a problem.
