SleeperZ Intake How-To;
Parts Needed;
2.75" to 2.75" 90 degree silicone elbow
2.75" to 3.00" 45 degree silicone elbow
atleast 16" of 2.75" stainless steel or aluminum pipe
Quantity 4 - 3.25" (or larger) pipe clamps (can be worm drive or t-bolt)
Duct Tape
Part Sources;
For silicone couplers -
AJ-USA.com
For pipe & silicone couplers -
atpTurbo.com
For pipe - your local exhaust shop
For duct tape - you should already have some
Procedure;
1) Pull off all the stock intake parts, set them aside
2) Remove the 4 big bolts sticking up from the TB
3) Drill a 2.75" round hole in the airbox where the stock trianglular shaped accordian tubing connects to it
4) Drill a 2.75" round hole in the fender where the stock trianglular shaped accordian tubing connects to it
5) Install 90 degree elbow on the TB
6) Install MAF on airbox
7) Install 45 degree elbow on the MAF
8) Install assembled airbox (with MAF and silicone elbow) into stock location on car
9) Measure distance from 90 degree elbow to 45 degree elbow, add 1"
10) Measure distance from hole in airbox to hole in fender, add 1"
11) Cut (or have cut) 2 pieces of pipe in the required lengths
12) If you have a pre 98 Contour, you'll need to drill a hole in the longer segment of pipe for the IAT
13) Install the pipe clamps on the silicone couplers (2 on each coupler), do not tighten
14) Install length of pipe between airbox and fender, to hold it in place use duct tape, 1/2" of pipe should stick into airbox
15) Install length of pipe between TB and MAF, it may take some force, but it will fit
16) Tighten hose clamps
17) If you have a Pre98, screw IAT into the hole you drilled
You now have a combination short ram & cold air intake that has most of the benefits of each.
Finished product should look similiar to this;
Options To This Intake Include;
1) Install a K&N (or other high flow) panel air filter
2) Install a velocity stack onto the airbox side of the air draw tube (so it will be inside the airbox)
3) Install a velocity stack on the fender side of the air draw tube (so it will be in the fenderwell)
4) Optimize the stock airbox by removing as many of the airflow obstructions as possible
5) Relocate the IAT to the intake manifold
6) Keep the stock plenum over the TB (the Contour needs one) and use 3" pipe and 3" silicone couplers
7) Coat the pipe in a heat resistane substance (either paint, heat wrap, ceramic, etc)
Definition Of Terms;
TB = Throttle Body
MAF = Mass Air Flow sensor
IAT = Air Inlet Temperture sensor
Velocity Stack = a funnel for air
Plenum = large flat toppped plastic air reseve chamber that sits over the TB
