Installing True Flow's XDI Air Intake on a 2008 Jeep Wrangler with a 3.8L V6
Installing an aftermarket intake system is one of the best way’s to improve your vehicle’s horsepower, torque, and throttle response. The True Flow XDI Xtreme Duty Intake features aluminum construction, mandrel-bent tubing, nilon-reinforced silicone couplers, and a foam air filter that is easily cleaned and comes with a lifetime warranty. We installed the XDI Xtreme Duty on a 2008 Jeep Wrangler with a 3.8L V6. True Flow lists the retail price for the XDI Air Intake at $359.00. Installation was very simple and can be done with simple hand tools in less than an hour.

 |  A look at the stock intake for the 3.8L V6 on our 2008 Jeep Wrangler |  First step is to disconnect the negative terminal connection on the battery |
 Unplug the sensor wire harness from the factory air tube |  Remove the rubber breather line from the stock air box |  Unscrew the clamps securing the stock air tube from the throttle body |
 Remove the stock air box and tube. The air box is not bolted in and can be removed simply by pulling it out of the factory grommets |  Remove the sensor from the factory air tube |  Install the sensor in the True Flow tube using the supplied grommet to secure the sensor from inside the tube |
 Clamp on the 2 3/4" x 3” coupler to the throttle body |  Install the True Flow tube into the open end of the coupler. Don’t completely tighten as it might need to be adjusted later |  Plug in the factory sensor wire harness |
 Remove the base of the XDI using an allen wrench |  It will require some effort to remove the base |  Remove any oil and residue from the XDI base and clamp on the True Flow filter |
 Once the filter is in place, reinstall the XDI with the supplied screws |  To install the XDI, the power steering reservoir needs to be unbolted. It only needs to be pushed aside and does not need to be completely removed |  The XDI will be bolted onto the fan shroud support, and that bolt needs to be removed first |
 Set the XDI in place |  The XDI will fit into one of the factory grommets |  The arm extending from the XDI did not quite fit exactly against the fan shroud support. Fortunately, it can be easily bent to properly fit |
 Once in place, bolt in the XDI to the fan shroud support. Make sure the XDI is securely in place and won’t come out of the grommet below |  Bolt the power steering reservoir back in place |  Install the 4” x 3” hump hose to the XDI using the supplied clamps |
 Reinstall the rubber breather line into the True Flow air tube |  Make sure that all of the clamps are completely tightened |  Reconnect the battery. Restart your vehicle and the ECM will reset and you should have no check engine light |
 The installation is complete! | | |
