How to Install JLT Ram Air Intake on your F-150

1. Verify you have all of the following parts included in the kit:
(1) JLT tube with IAT and PCV fittings, (1) 3.5 x 2" Silicone Coupler, (1) 3-3.5" x 3" Silicone Reducer,
(4) #56 Clamps, (1) 4x12” Oval Air Filter, (1) MAF Adaptor with bolts, (1) MAF Gasket, (1) MAF Wire Harness
Extension, (1) Section of 3/4” Hose, and (1) Section of 5/8” Hose (2) Small Clamps

2. Gather all of the following tools needed for the installation:
5/16 Nut Driver, 10mm Open End Wrench, 11mm Open End Wrench, Wire Cutters/Strippers, Regular Screwdriver

3. Remove the stock intake from the throttle body to the air box.

4. Disassemble the stock air box in order to remove the MAF sensor.
Shown in picture below:

5. There are 4 bolts holding the MAF sensor in the air box. Unbolt the MAF and pull wire harness through the hole. Once the MAF is out, bolt the JLT supplied Billet MAF adaptor to the MAF with the supplied bolts and gaskets.

6. Install the silicone reducer and coupler onto the JLT pipe. This is to connect to the throttle body. Note, the larger fitting on JLT pipe will be closest to the throttle body. Install MAF unit in silicone coupler making sure the plug is pointing down as shown in the picture below.

8. Install air filter on MAF adaptor making sure it’s fully seated against the back of the adaptor.

9. Pull the IAT sensor from the stock inlet pipe and install into the hole in the JLT filter
It will fit a little loose, but this is not a problem.

10. Now install the assembly onto the throttle body.

11. Using supplied ¾” hose, connect the larger IAC line to the JLT fitting and the PCV hose to the second (forward most) fitting. Note; we have included a piece of 5/8” hose as we have been advised that it may be needed to connect the PCV hose in some models. Also note, we include extra hose so you will have to cut it to fit.

12. Use included MAF wire harness to plug in your MAF sensor and reinstall your engine cover.

13. Installation is complete.
