How to install a JLT Performance Next Generation Ram Air Intake on your 2003-2004 Cobra Mustang

Verify you have all of the following parts included in the kit:

(1) JLT Intake tube with PCV fitting, Vacuum Fitting, and IAT grommet, (1) Vacuum line, (1) 4.5"x2" Silicone Coupler, (1) 4.5"-4" Silicon Reducer, (1) MAF Gasket, (1) MAF Adaptor with bolts, (3) #72 Clamps, (1) #64 clamp, (1) PCV fitting cap, (1) Vacuum fitting cap, (1) 4x9” Air Filter and (1) Heat shield

1. Gather all of the following tools needed for the installation:

2. Remove your stock intake system from the throttle body to the filter housing.

Pull the thin, hard vacuum line out of the large connection on the stock intake tube.

3. Unbolt your Mass Air Flow Sensor from the filter housing, and install the MAF filter adaptor using the supplied MAF gasket and bolts shown below. Do not reuse the screen BOLTS GO THROUGH MAF AND THREAD INTO ADAPTOR.

4. Install the filter onto the MAF adaptor and the silicone reducer onto the MAF.

5. PULL the Inlet Air Temperature sensor from your stock inlet and install in the grommet on bottom side of JLT tube.

6. Install Throttle body coupler onto JLT tube, then the tube into silicone reducer making a complete unit from throttle body to filter.

7. Tuck air filter behind the headlight and lower down onto throttle body. Tighten only the clamp on throttle body.

8. Plug in IAT sensor, MAF sensor, PCV connection and vacuum line (using supplied vacuum tubing). Using the stock air box bolt, install the heat shield. If you are NOT using the PCV or Vacuum line use the supplied caps to seal the fittings.

9. Go back and make any adjustments to the tube and tighten the clamps (ONLY FINGER TIGHT). Installation is complete.

This kit includes an S&B Powerstack pre-oiled reusable air filter. The frequency you should clean your filter will depend on your driving conditions. It is recommended to check your filter at every oil change or 3,000 miles. If there is a build up of dirt as thick as the wire mesh, then it’s time to clean your filter. As dirt builds up on your filter, the restriction of the airflow also increases. More frequent cleanings will improve your fuel economy and your vehicle’s performance.
