|This guide has been written to give you step by step instructions on how to replace your stock air box with the JLT Cold Air Intake (CAI) This article covers both the installation for manual transmissions AND automatic transmissions. This installation is very simple and requires only regular hand tools. It should take you around 30-45 minutes from start to finish depending on your transmission type.

The tools needed for this installation are:
|I thought we would begin by taking a look at the stock air box. There are obvious restrictions in airflow.|
|Now we can go over the parts that JLT provides for you. The most obvious is the carbon fiber inlet tubing and the high flow air filter with clamp. Next you will see the rubber coupler and two clamps (one smaller than the other).
They will also provide you with two screws for the mass air sensor. A heat shield is included but not pictured. They also include a rubber grommet and plastic fitting, for those of us with automatic transmissions, that we will go into further detail on, later in this guide.
|Begin by taking your flat head screwdriver and loosen the band clamp closest to the throttle body.|
|FOR AUTOMATICS ONLY (skip this step if you have a manual): Remove the vacuum hose by pulling back as pictured on the left.|
|Remove the crank case vent tube by pushing the gray tab back as pictured to the left and pull it off.|
|Next you will need to remove the mass air sensor which only requires you to remove two screws (top left and bottom right) as shown in the picture to the left (the bottom right screw has already been removed).|
|Then you must remove the clip that attaches the wires of the mass air sensor to the stock air box.|
|Once you remove the clip and screws, you may now pull the mass air sensor out of the stock air box as shown to the left. Set it aside.|
|Next you will need to remove the bolt retaining the stock air box to the fender with a 10mm socket (using the 6″ extension will make removal much easier).|
|Now that you have loosened the clamp, removed the vent tube and vacuum hose, removed the 10mm bolt and mass air sensor, you are ready to pull the stock air box out. Just pull up and out, it will come out with little effort.|
|If you did it right, this is what your engine compartment will look like. Congratulations! You’re half way there.|
|FOR AUTOMATICS ONLY (skip this step if you have a manual): JLT provides you with a rubber grommet and plastic fitting (they have already been installed in this picture). This will be used if you have an automatic so you may attach the vacuum hose that you pulled off a few steps ago. This is when the 3/4″ drill bit comes in handy. JLT puts a slight dent into the tubing where you will drill the hole for the grommet. When you drill the hole, be careful to go slowly so not to crack the clear coat on the tubing. Once the hole is ready, pop the grommet in and you will “screw” the plastic fitting into the rubber grommet using the adjustable wrench.|
|A rubber coupler and two large clamps have been provided to attach the tubing to the throttle body. Be sure to put the smaller clamp on before installing the coupler to the throttle body as it can not fit around the larger end of the coupler. Then you can add the second larger clamp. Keep both clamps loose.|
|You will also be provided with a heat shield. Go ahead and set it in the engine compartment as pictured to the left, but it’s not necessary to bolt it down just yet.|
|You may now install the carbon fiber intake tubing by first, sliding it through the hole of the heat shield, and then pushing the other end into the rubber coupler.|
|Now, take your flat head screwdriver and tighten down those hose clamps, but not too tight! It only needs to be snug enough to keep it leak free.|
|Once we have the tubing secure, we can move back to the heat shield and secure it. The first thing you will notice is that there is a stud (top left of picture) that you will be using to secure one end of the heat shield. Slip the stud through the hole of the heat shield.|
|You will notice that it doesn’t fit securely around the stud. I just so happened to have an extra 10mm nut that fit on the stud, so I secured it that way. This is personal preference since JLT didn’t provide a nut, but you certainly want to keep as much heat away from the filter as possible. I mean, that is the point of a heat shield, right?!|
|Next take that 10mm bolt you removed earlier and tighten it back down to finish securing the heat shield.|
|Now you’re ready to put the mass air sensor into the new intake tubing. JLT did a great job at keeping a very clean look. The sensor sits flush to the tubing and all you need to do is screw in the two screws provided by JLT. You will also want to tighten down the clamp on the filter at this point.|
|Clip the vent tube back into place.|
|FOR AUTOMATICS ONLY (skip this step if you have a manual): Remember the fitting you drilled a hole for and installed a few steps ago? Slip the vacuum hose over the fitting.|
|CONGRATULATIONS!!! You did it! You can now reap the rewards of owning this fabulous intake. BUT before you start the car up, make sure you have everything tightened down and secured and you have removed all extra parts and tools out of the engine compartment. Now start it up and enjoy!|
