SRT-4 Engine Upgrade: Hoses and Air Intake Show-Car Engine Dress-Up, Part 4 of 4 From "Tricked Out" episode DTRK-306

	Before
	After

In this final phase, Andrew completes the engine upgrades by covering the air intake with wrap that will not only add some shine under the hood, but will also insulate the pipe from turbo heat to allow for a nice cold, dense air charge. He also adds shine by wrapping existing hoses in braided wrap and split loom.

Materials and tools needed for the final phase of this project:

utility knife
supplied metallic tape
drip pan
heat shield wrap
braided wraps
split loom
silicone tubing

Steps:

• The first step is to remove the air intake. The hose clamp at the turbo gets removed and two vacuum lines need to come off as well. Unplug the air temperature sensor, and loosen the mounting bracket nut near the air filter (figure A) to allow the intake to pull out.

• At a worktable, pull off the air filter and then lay the wrap along the tube.
  

• Cut a small slit for the mounting bracket to fit through, and then pull the wrap tight over where the sensor hole is and cut out a hole around the grommet (figure B).

• Use a utility knife to carefully tuck the fabric underneath the grommet (figure C).

• Continue covering the intake with heat wrap, securing it with the attached hook-and-loop closure and cutting out the access holes as you go.
  Then cut off the excess wrap and secure it on each end with the supplied metallic tape.

• Finish by sliding on the air filter, and then take the intake back to the car and reinstall it (figure D), being sure to hook up all the lines and sensors correctly.

• Now that the intake is on, you can add some more touches of silver and red to the car by adding braided stainless steel sheaths to the existing hoses. You can pick up a kit that includes several sizes to fit various hoses and lines.

• Begin with the radiator hose. First loosen the radiator cap.

• Open the petcock valve to drain about a gallon of coolant into a drip pan so the hoses on top of the engine won't be full.

• Next, release the hose clamps, pull the radiator hose off of the car on each end, and drain the hose into the drip pan.

• Take off the old hose clamps and remove any existing sleeves, then work the braided sleeve over the length of the hose and cut off the end.

• The hose clamps go back on, and then the sleeve is trimmed to the very end. The clamps are covered by end clamps that slide right on (figure E).

• Do this on both sides, and then attach the hose back to the car.

• The overflow hose get the same braided steel treatment.

• Once the hoses are covered, you can top off the coolant.

• Silver wire loom can be cut to size to cover many of the other lines like the air-conditioning line and any others that are visible on the top layer of the engine (figure F).

Important: Included in this summary are the steps in this automotive procedure as shown in the episode. These steps are general guidelines that are applicable to most vehicles. With any particular car or truck, there may be procedures, specifications, settings, tolerances, components, etc. that are specific to that vehicle. There are also variations according to the type and brand of upgrade-kit you select. Always consult your vehicle's service manual when undertaking significant automotive repairs, and read and follow the manufacturer's directions and precautions that come with your kit or replacement parts.
